The 10 worst American States to travel to This Summer
Summer travel demand remains high across the U.S., with AAA projecting tens of millions of Americans on the road around major 2026 holiday periods and federal weather agencies again warning about heat and storm disruptions. Looking state by state, the toughest summer trips are usually tied to measurable problems such as extreme temperatures, hurricane exposure, wildfire smoke, flood risk, and peak-season crowding. This list highlights 10 states where those factors are most likely to complicate a summer visit.
Florida
Florida remains the country’s busiest summer weather risk zone because the Atlantic hurricane season officially runs from June 1 through November 30, according to NOAA. The state also logged some of the nation’s heaviest summer tourism volumes in places like Orlando and Miami, based on Visit Florida reporting from recent seasons.
Heat is also a factor. The National Weather Service regularly posts heat advisories across Central and South Florida in July and August, with heat index values often topping 105 degrees in cities such as Tampa, Orlando, and Jacksonville.
For travelers, that means a higher chance of flight delays, afternoon thunderstorms, crowded roads on I-95 and I-4, and expensive last-minute hotel changes. Florida is still one of America’s most visited states, but summer conditions are among the least predictable.
Texas
Texas covers 268,596 square miles, and summer travel problems vary sharply by region, but heat is the common thread. In recent summers, the National Weather Service issued repeated excessive heat warnings for cities including Dallas, San Antonio, Austin, and Houston, with air temperatures reaching well above 100 degrees.
The Gulf Coast adds another layer of risk. Hurricane season affects cities such as Corpus Christi, Galveston, and Houston, while inland flash flooding can shut roads quickly, according to the Texas Division of Emergency Management.
Travelers also deal with distance. A drive from El Paso to Houston is roughly 745 miles, and long road trips during peak heat can increase fuel, lodging, and safety concerns, especially during July weekend traffic.
Arizona
Arizona is one of the clearest summer avoid states because Phoenix routinely posts some of the hottest big-city temperatures in the country. In 2024, Phoenix set records for prolonged heat, and the National Weather Service has repeatedly warned that pavement and trail conditions can become dangerous even in the morning.
Outdoor recreation is the biggest issue. Popular areas near Phoenix, Scottsdale, and Tucson often face trail restrictions, wildfire concerns, or medical rescue alerts during heat spikes, according to local fire agencies and Maricopa County officials.
Even when attractions stay open, the experience can be limited. Midday sightseeing around the Sonoran Desert, Camelback Mountain, or Papago Park often becomes unrealistic when temperatures climb past 110 degrees.
Louisiana
Louisiana combines high humidity, hurricane exposure, and flood risk in a way few states do. New Orleans in particular faces repeated summer drainage and street flooding problems during intense rain events, according to the National Weather Service and local emergency management updates.
The heat is not just uncomfortable but persistent. Summer heat index readings over 100 degrees are common in Baton Rouge and New Orleans, and Gulf moisture can keep overnight lows elevated, reducing relief for visitors.
For tourists, that can mean disrupted walking plans in the French Quarter, pop-up storm delays, and higher stress for road travel along low-lying coastal routes. The state’s culture remains a huge draw, but summer can be its hardest season.
Nevada
Nevada makes this list mostly because of Southern Nevada. Las Vegas regularly posts July highs above 105 degrees, and Harry Reid International Airport handles huge visitor volumes at the same time, according to airport and local tourism figures.
Extreme heat changes how much travelers can actually do. Long walks on the Strip, day trips to Red Rock Canyon, and Hoover Dam visits can become limited during afternoon hours, especially when the National Weather Service issues extreme heat warnings.
Hotel capacity is strong, but that does not erase the climate problem. Summer visitors may find lower room rates than spring, yet the tradeoff is a city where basic outdoor movement can become difficult by midday.
South Carolina
South Carolina’s travel risks center on its coastline. Hurricane season threatens beach destinations such as Myrtle Beach, Hilton Head, and Charleston, and even near-miss systems can bring dangerous surf, heavy rain, and evacuation traffic, according to the South Carolina Emergency Management Division.
Crowding is another issue. Myrtle Beach is one of the East Coast’s busiest family beach markets in summer, and state tourism data has consistently shown major seasonal volume along the Grand Strand.
That combination can affect everything from hotel pricing to highway backups on routes like U.S. 17 and Interstate 26. Visitors may still get beach weather, but they are also taking on one of the region’s more volatile summer setups.
Alaska
Alaska lands on this list for a different reason. Summer is its prime season, but that also means sharp price pressure, limited availability, and transportation bottlenecks, especially in Anchorage, Denali, Seward, and cruise-linked ports such as Juneau and Ketchikan.
Weather still matters here too. Even in July, rain, marine delays, and changing visibility can affect excursions, while wildfire smoke has disrupted parts of Alaska during recent summers, according to state and federal fire updates.
The state’s scale is another obstacle. Alaska spans more than 663,000 square miles, and missed connections or weather shifts can have outsized effects when travelers are relying on ferries, bush flights, or fixed cruise schedules.
California
California’s summer travel appeal is obvious, but so are its risks. Wildfire season has repeatedly overlapped with peak vacation months, and Cal Fire and air quality agencies have warned that smoke can affect areas far from an active fire line.
The state also deals with crowding on a large scale. Coastal routes, national park gateways, and metro airports around Los Angeles, San Diego, and San Francisco can see major backups during July and August.
Heat adds to the strain inland. Places such as Palm Springs, Sacramento’s interior valleys, and parts of the Central Valley can post triple-digit temperatures, making California one of the most logistically uneven summer trips in the country.
Mississippi
Mississippi is often overlooked in national travel rankings, but summer conditions can be punishing. Cities such as Jackson, Gulfport, and Hattiesburg regularly see high humidity and heat index values above 100 degrees, according to National Weather Service offices serving the state.
The Gulf Coast also stays exposed during hurricane season. That affects beach travel near Biloxi and Pascagoula and can create fast-changing lodging and road conditions when tropical systems enter the Gulf of Mexico.
For many visitors, the challenge is not a lack of attractions but the weather window. Outdoor sightseeing, casino-area walking, and road trips become harder when intense heat and storm chances build almost every afternoon.
New Jersey
New Jersey may surprise some travelers, but summer here can be unusually frustrating because of density, shore traffic, and storm volatility. The Garden State Parkway and routes serving the Jersey Shore are known for major backups during peak weekends, according to state traffic reporting.
Beach demand pushes prices up in places like Cape May, Ocean City, and Point Pleasant, while thunderstorms and occasional coastal flooding can interrupt short trips. The state is also vulnerable to tropical remnants during the Atlantic season.
That makes New Jersey less about extreme wilderness risk and more about friction. A state with about 9 million residents packed into one of the nation’s smallest land areas can feel especially strained during summer peak travel.
