The 10 Hottest States in the USA 2026

Do you know that Florida is the hottest US state by annual average temperature at 72.6°F. But, Texas takes the crown when only summer months are measured. That means the answer to what is the hottest state in USA depends entirely on which question you're actually asking.

Most people confidently answer Arizona. It's an understandable guess. Phoenix spends much of the summer above 100°F, Yuma regularly reaches temperatures that seem impossible outside a desert, and Arizona's reputation for heat is unmatched. But statewide climate rankings tell a very different story.

When all 12 months are counted, the southeastern states tend to be hotter than the Southwest. Florida, Georgia, Louisiana, and Mississippi stay warm throughout the year, while Arizona's mountains quietly pull its statewide average down.

That's the part most rankings never explain properly. The practical implications go beyond weather trivia. Heat affects utility bills, storm preparation, outdoor activities, and even the equipment mounted outside your home.

How These Hottest States Rankings Work

Climate rankings generally use one of two methods. Florida ranks first because it was measured using annual average temperature, which combines all 12 months into a single figure. As for Texas, it's the hottest because it's measured based on summer averages, typically June through August.

Annual averages naturally favor southeastern states such as Florida and Georgia because they remain warm even during winter. Summer-only rankings favor Texas and Louisiana because their hottest months are often more intense.

For someone comparing year-round climates, annual averages provide the more useful answer. For a traveler planning a July road trip through the Southwest, summer averages matter more.

For this research-backed article, we take annual averages as the primary ranking method because they better represent what living in a state actually feels like over the course of a year. All primary climate data is based on NOAA climate normals.

The 10 Hottest States in the USA, Ranked

Florida and Georgia share the #1 position by annual average temperature at 72.6°F, but the similarities end there. Some states earn their ranking through relentless humidity. Others rely on tropical consistency or desert extremes. The top ten may look straightforward on paper, yet each state arrives here for a different reason.

Florida

Florida wins the annual ranking because the Sunshine State simply does not cool down for long periods of time.

While other states on this list experience meaningful winters, much of Florida remains warm year-round. Northern Florida operates under a humid subtropical climate, while South Florida crosses into a true tropical climate. The result is a statewide average temperature of 72.6°F, the highest in the nation.

Summer temperatures frequently reach the low 90s, but the bigger story is consistency. Even January feels like spring compared to much of the country.

Heat is only part of Florida's identity, however. Hurricane season runs from June through November, meaning residents spend as much time preparing for storms as they do preparing for heat.

Georgia

Georgia ties with Florida at the top, but it earns that ranking through contrast rather than consistency.

Southern Georgia often feels like an extension of North Florida. Summer temperatures between 90°F and 100°F are common, and humidity remains a constant presence. Head north toward the Appalachian foothills, however, and the climate changes noticeably.

Few states demonstrate climate diversity as clearly as Georgia. The same state that delivers sweltering summer afternoons near Valdosta can offer surprisingly comfortable mountain weather near Blue Ridge.

That geographic range makes Georgia one of the most interesting entries in the top ten.

Louisiana

If this ranking measured discomfort instead of temperature, Louisiana would have a legitimate claim to first place.

The heat index defines life here. During August, air temperatures above 90°F combine with Gulf humidity to create conditions that can feel well above 110°F. In extreme cases, the heat index exceeds 120°F.

Shade helps less than people expect. Sweat evaporates poorly. Outdoor work becomes exhausting quickly.

Louisiana records around 90 days above 90°F each year, but the real challenge isn't the number on the thermometer. It's the humidity that comes with it.

Texas

Texas is the reason the hottest-state debate never truly ends. If summer alone determined the rankings, Texas would likely sit at or near the top. Cities across southern and western Texas routinely spend August between 93°F and 101°F.

The problem is size.

Texas covers more than 268,000 square miles and contains multiple climate zones. East Texas resembles Louisiana. West Texas resembles New Mexico. The Panhandle behaves differently from the Gulf Coast.

When NOAA averages all those regions together, Texas settles into fourth place. When people remember only the summer heat, they often place it first.

Both perspectives are understandable.

Hawaii

Hawaii may be the most surprising state on this entire list.

Unlike Louisiana, Texas, or Arizona, Hawaii reaches the top five without relying on extreme temperatures. Most of the islands spend the year hovering comfortably in the 70s.

Summer highs often average around 77°F. Winter barely exists by mainland standards. Temperatures almost never fall below freezing and almost never exceed 100°F.

In many ways, Hawaii represents the opposite of Arizona. Arizona produces some of the hottest temperatures on Earth. Hawaii produces some of the most consistent temperatures anywhere.

Its ranking comes from stability, not intensity.

Mississippi

Mississippi is exactly what many people imagine when they hear the phrase "hot southern summer."

Temperatures above 90°F are common for months at a time. Humidity remains high. Winters are mild enough that snow becomes an occasional novelty rather than an annual expectation.

The state's climate lacks the dramatic extremes found in Arizona or Texas, but it compensates with persistence. Warm weather arrives early, stays late, and rarely leaves for long.

That consistency keeps Mississippi comfortably inside the top ten.

Alabama

Alabama's climate follows the familiar Gulf Coast formula of long summers, short winters, and plenty of humidity.

The Gulf of Mexico helps moderate some of the state's most extreme temperatures, preventing Alabama from climbing higher in the rankings despite spending much of the year in warm conditions.

Residents still experience lengthy stretches above 90°F during summer. Combined with humidity, those temperatures often feel significantly warmer than they appear on paper.

South Carolina

South Carolina earns its position through a blend of coastal warmth and mild winters.

The Atlantic Ocean helps maintain comfortable temperatures throughout much of the year, but summers remain undeniably hot. Coastal communities experience more moderation, while inland regions often feel considerably warmer.

Higher elevations in the northwest provide some relief, but not enough to push South Carolina out of the top ten.

Arizona

Arizona is the answer most people expect. It just isn't the correct statewide answer.

Phoenix averages above 100°F from June through August. Yuma, sitting only 141 feet above sea level, regularly experiences summer highs between 110°F and 120°F.

Those numbers sound like an automatic first-place ranking. But, if you drive north, Flagstaff sits nearly 6,900 feet above sea level and experiences winters colder than many parts of Colorado. Snowfall is common. Winter temperatures can also drop below freezing for extended periods.

This enormous elevation difference is what most rankings fail to explain. Arizona contains some of the hottest cities in the world, but it also contains mountain communities that dramatically lower the statewide average.

Average Phoenix, Yuma, Flagstaff, and the rest together, and Arizona lands ninth rather than first.

The misconception persists because people remember Phoenix and forget the mountains.

Arkansas

Arkansas rounds out the list because it experiences genuine heat while still maintaining recognizable seasons.

Summer afternoons frequently climb into the 90s, particularly in eastern portions of the state. Humidity remains high enough to make those temperatures feel even warmer.

Unlike most states above it, however, Arkansas still experiences winters cold enough for occasional snow in Little Rock and surrounding areas.

That seasonal variation is exactly what keeps Arkansas at the bottom of the top ten rather than pushing it higher as seen in NOAA climate normals and historical temperature record.

What Extreme Heat Actually Feels Like

The difference between 95°F in Phoenix and 95°F in New Orleans is enormous. One can feel manageable in the shade. The other can feel like walking into a wall of moisture.

That's because temperature alone does not determine comfort. Humidity plays an equally important role.

In humid subtropical states such as Florida, Louisiana, Georgia, Mississippi, Alabama, South Carolina, and Arkansas, the air already contains significant moisture. Your body cools itself through evaporation. When the air is saturated, sweat evaporates more slowly, making it harder to regulate body temperature.

That is why Louisiana's heat index can climb above 120°F even when the actual air temperature is much lower.

Arizona presents the opposite challenge. Much of the state is arid or semi-arid, meaning sweat evaporates quickly. Temperatures above 105°F remain dangerous, but shade and airflow provide meaningful relief because the body's cooling mechanisms still function effectively.

Storm seasons add another layer of complexity. Florida, Louisiana, Texas, and South Carolina sit directly within active hurricane corridors. Preparing for tropical storms becomes part of the annual routine. Outdoor furniture gets secured. Drainage systems get checked. Insurance policies get reviewed. These are not occasional concerns. They are seasonal responsibilities.

Energy consumption follows the heat. The warmest states in America consistently rank among the country's highest users of residential electricity because air conditioning often runs continuously from late spring through early autumn. Many newcomers underestimate their first summer utility bill simply because they have never experienced a climate where cooling is required for months at a time.

The relationship between heat and crime is less obvious but equally important. A large meta-analysis published in Environmental Health Perspectives found that higher short-term temperature exposure is significantly associated with increased violent crime rates across multiple countries and decades of research.

The mechanism is well documented by the National Library of Medicine. Heat increases physiological stress, irritability, and aggression while also placing more people outdoors, increasing opportunities for conflict.

A companion US-focused study examining 44 cities reached similar conclusions. This does not mean hot states are inherently unsafe. It does mean the conditions that create extreme summer heat also correlate with elevated security risks. Louisiana consistently ranks among the highest states for homicide rates, while Texas and Florida sit above the national median for violent crime.

For homeowners, that makes outdoor security less of a luxury upgrade and more of a practical part of living in the Sun Belt.

Keeping Your Home Secure in a High-Heat State

According to Pinkerton Research, summer is both the season when security risks increase and when outdoor security equipment is placed under the greatest strain. Higher temperatures and prolonged sun exposure can affect the performance and durability of surveillance systems.

At the same time, crime patterns tend to shift during the summer months, making effective deterrence even more important. National studies have consistently shown that visible security cameras reduce crime, which means homes with clearly visible surveillance are significantly less likely to be targeted.

The challenge is that deterrence only works IF the equipment remains operational.

Many outdoor cameras carry an "outdoor-rated" label but are tested only to withstand high temperatures between 104°F and 113°F (40°C–45°C). In states like Arizona, Texas, Louisiana, and Florida, a camera mounted on a west-facing wall can experience surface temperatures 20°F to 30°F higher than the surrounding air temperature.

The specifications that matter most in hot climates are:

• Temperature tolerance range up to 55°C (131°F)
• IP66 weatherproofing
• Local storage options
• Reliable operation during power outages

Pro Tip: If you're new to weather ratings, the Reolink guide on IP66 weatherproofing explains why dust resistance and protection from high-pressure water matter just as much as heat tolerance in hurricane-prone regions.

For renters or homeowners who do not want to run cables immediately, a solar-powered battery security camera is usually the easiest starting point.

The Reolink Argus 4 Pro is particularly well suited to hot-climate deployment. It operates up to 55°C (131°F), carries an IP66 rating, runs from a 5000mAh rechargeable battery, and supports the optional solar panel. In states averaging 250+ sunny days annually, solar charging can dramatically reduce maintenance requirements.

For homeowners installing a permanent system, the Reolink RLC-823A offers a different approach. It uses PoE (Power over Ethernet) rather than battery power and combines 4K resolution, 5× optical zoom, 360° pan, 90° tilt, and auto-tracking. Such a package of functions ensure you get a complete field of view and enables you to attain a stable and clear footage, whenever required. The same IP66 weatherproofing and 55°C operating specification make it suitable for the hottest states on this list.

Placement matters almost as much as camera choice. Mounting cameras under eaves, soffits, or shaded overhangs can reduce surface temperatures substantially. Shade often lowers equipment temperatures by 20°F or more, extending lifespan and reducing thermal stress.

For most homes, the highest-priority positions remain:

• Front door
• Driveway
• Main side access path

Storm season creates a separate security challenge.

Ready.gov recommends property owners to secure entry points ahead of hurricanes, yet the security risks created by evacuation are often underestimated. Empty homes and abandoned neighborhoods have historically led to increased criminal activity after major storms.

The most common failure point for surveillance systems during these events is not wind damage. It is power loss.

Cloud-dependent cameras frequently stop recording once electricity and internet service fail. Battery-powered cameras with onboard microSD storage continue recording locally even when connectivity disappears.

For long-term resilience, the Insurance Institute for Business & Home Safety promotes its FORTIFIED Home standard, which focuses on stronger roofs, improved sealing, and better storm resistance.

For homeowners in Florida, Louisiana, Texas, and South Carolina, combining resilient construction with weather-rated surveillance equipment creates a far more durable security strategy than relying on either one alone.

Conclusion

Florida wins the annual-average debate. Texas wins the summer-only debate. Arizona contains the hottest cities but not the hottest statewide climate. Once the methodology question is settled, the more important takeaway is understanding what life in these states actually involves.

Heat affects everything from utility bills and hurricane preparation to outdoor comfort and home security. For people relocating to the Sun Belt, planning for those realities matters far more than memorizing a ranking table.

FAQs

What is the hottest state in the USA?

Florida is the hottest US state by annual average temperature at 72.6°F, while Texas leads when only summer months are measured. Both answers are technically correct because they use different methodologies. The top ten is dominated by southern and southeastern states, with no Midwestern or Northeastern state making the list.

Why isn't Arizona the hottest state?

Arizona contains some of the hottest individual cities on Earth, but its statewide average is lowered dramatically by elevation. Phoenix and Yuma experience extreme desert heat, while Flagstaff sits nearly 6,900 feet above sea level and experiences snowy winters. Averaging those climates together places Arizona ninth rather than first.

What is the difference between humid heat and dry heat?

In Arizona, sweat evaporates quickly and shade provides meaningful relief. In Louisiana or Florida, humidity slows evaporation and makes the same temperature feel far more uncomfortable. This difference is why a 95°F day in New Orleans often feels significantly worse than a 95°F day in Phoenix.

Is it safe to live in a hot state?

Safety varies far more by city and neighborhood than by statewide averages. While some of the hottest states rank above the national median for violent crime, many communities within those states are exceptionally safe. Outdoor cameras, motion alerts, and smart home security systems have become a standard part of home setup across much of the Sun Belt.
