How to Beat Extreme Heat While Traveling: 12 Tips That Actually Work

Summer 2026 has been scorching. Europe shattered temperature records, Salt Lake City hit 109°F, and cities like Phoenix and Las Vegas saw stretches of triple-digit heat that made stepping outside feel like opening an oven. If you have travel plans this summer, whether domestic or international, you need a strategy for dealing with extreme heat that goes beyond “drink more water.”

Here are 12 tips that actually work, drawn from people who live in extreme heat cities and from travelers who survived Europe’s record-breaking summer.

Plan your day around the heat, not the other way around

The single most important adjustment you can make is timing. In most hot climates, peak heat falls between noon and 5 p.m. That window is when temperatures top out, UV index peaks, and the pavement radiates stored heat from the morning.

Phoenix and Las Vegas locals told the Salt Lake Tribune they just stay indoors during those hours. When it is 110°F outside, that is not extreme. It is survival.

For travelers, this means reworking your itinerary. Schedule outdoor sightseeing for early morning (before 10 a.m.) or evening (after 6 p.m.). Use the afternoon for indoor activities: museums, restaurants, shopping centers, or your hotel’s pool. This is not lazy planning. It is the difference between enjoying your trip and spending it recovering from heat exhaustion.

Seek out naturally cool buildings

Many European cities have an advantage that desert towns do not: thick stone buildings that have been naturally cooling people for centuries. Churches, museums, train stations, and shopping centers are often several degrees cooler than the streets outside.

When you are walking through Rome, Barcelona, or Athens in August, duck into a cathedral or a museum during the hottest part of the day. You will not just escape the heat. You will also see some of the best architecture in the world while staying comfortable.

In modern cities, look for public libraries, government buildings, and large commercial spaces with air conditioning. Most malls welcome browsers, and hotel lobbies are generally open to the public.

Carry more water than you think you need

Dehydration does not announce itself. By the time you feel thirsty, your body is already running low. Health experts say you should plan water stops every 20 to 30 minutes in extreme heat, which is more often than most people think.

A reusable water bottle is non-negotiable. In European cities, many have public fountains with potable water. In the American Southwest, gas stations and convenience stores are your refilling stations. If you are hiking or doing any outdoor activity in extreme heat, consider a hydration pack that lets you sip continuously without stopping.

One trick from experienced desert travelers: add a pinch of salt to your water or carry electrolyte packets. Plain water alone can actually dilute your sodium levels if you are sweating heavily, which leads to cramping and fatigue.

Skip heavy meals during the day

Rich, heavy food forces your body to work harder to digest, which raises your internal temperature and makes you feel sluggish. In normal weather, this is a mild inconvenience. In extreme heat, it can push you toward heat-related illness.

During the hottest part of the day, stick to lighter fare: salads, fruit, sandwiches, chilled soups, or anything that does not require your body to generate extra heat through digestion. Save the big dinner for evening when temperatures drop and your body can handle the metabolic load more comfortably.

This is also a good time to reduce alcohol and caffeine intake. Both are diuretics, meaning they make you urinate more and lose fluids faster. If you want a cold drink with lunch, water or coconut water are better choices than a beer or iced coffee.

Dress for survival, not for Instagram

This one is hard for travelers who want to look good in photos, but it matters. Dark, tight clothing absorbs and traps heat. Light-colored, loose-fitting, breathable fabrics like linen or moisture-wicking synthetics allow air to circulate and sweat to evaporate.

A wide-brimmed hat protects your face and neck far better than a baseball cap, which leaves your ears and the back of your neck exposed. Sunglasses are not just a style choice. They protect your eyes from UV damage and reduce squinting, which causes headaches.

If you are visiting a place with a strong dress code, like certain religious sites in Europe or the Middle East, plan for it. Bring a lightweight shawl or cover-up that meets requirements without adding unnecessary layers.

Use cooling tools that fit in your pocket

A small battery-powered fan or a cooling towel can make a surprising difference when you are standing in line at a museum, riding a crowded bus, or walking through a market with no shade. Cooling towels work by retaining cold water and releasing it slowly as they warm up. Wet it, wring it out, and drape it around your neck.

Portable fans have gotten better and cheaper. Some models are small enough to clip onto a bag strap or hang around your neck. They will not replace air conditioning, but they create enough airflow to lower your perceived temperature by several degrees.

These tools weigh almost nothing and take up minimal space in your bag. There is no reason not to have them.

Know the signs of heat exhaustion

Heat-related illness kills more people in the United States each year than any other weather event, according to the National Weather Service. The early signs are easy to miss because they mimic simple tiredness: heavy sweating, weakness, cold or clammy skin, nausea, and headache.

If you or someone in your group starts showing these symptoms, stop all activity immediately. Move to a cool, shaded area. Apply cool, wet cloths to the skin. Sip water slowly. If symptoms do not improve within 30 minutes or if vomiting begins, seek medical attention.

Heatstroke is a medical emergency. Symptoms include hot, red, dry skin (no sweating), a body temperature above 103°F, confusion, and loss of consciousness. Call emergency services immediately.

Prevention beats treatment every time. That is why the timing and hydration tips above matter.

Map your water and shade in advance

Before you head out for the day, take five minutes to look at your route on a map. Identify public water fountains, shaded parks, indoor rest stops, and air-conditioned spaces along the way. This is especially important in cities you have never visited before.

In many European cities, you can find free water fountains marked on tourist maps. In the American West, plan your stops around gas stations and convenience stores. If you are doing a walking tour, ask the guide where the shade breaks and water stops are.

This small bit of preparation prevents the common problem of being stuck on a long, exposed stretch of road with no water and no shade in sight.

Use your hotel room strategically

Your hotel room is your coolest refuge, but only if you use it right. Close the curtains or blinds during the day to block solar heat gain. If your room has a balcony, keep the door closed during peak heat hours.

Run the air conditioning before you leave in the morning so the room is cool when you return. If you do not have A/C, a fan pointed at a bowl of ice can lower the room temperature noticeably.

When you return from a hot day out, do not jump straight into a cold shower. That can cause blood vessels to constrict rapidly and make you feel worse. Instead, rinse with lukewarm water first, then gradually lower the temperature.

Protect your electronics and medications

Extreme heat damages more than people. Phones overheat and shut down. Medications can lose effectiveness. Sunscreen degrades. Chocolate melts. Batteries drain faster.

Keep your phone in the shade or in an insulated bag. If it does overheat, remove the case and let it cool naturally. Do not put it in a refrigerator or freezer, as the rapid temperature change can cause condensation inside the device.

If you carry medications, keep them in your coolest bag, not in a car trunk or a backpack sitting in the sun. Some medications, including certain antibiotics and insulin, can become less effective or even harmful when exposed to high temperatures.

Adjust your pace and expectations

This might be the most important tip on the list. In extreme heat, you cannot move at the same pace you would in mild weather. Accept that you will see fewer things each day, walk more slowly, and take more breaks.

That is not failure. That is smart travel. Trying to power through a 10-mile walking tour in 105°F heat is how people end up in emergency rooms. Slow down, drink water, and enjoy what you are doing instead of rushing through it.

Experienced travelers in hot climates tend to save their biggest outdoor activities for the first or last day, when energy is highest. The middle of the trip gets lighter plans and longer rest breaks.

Carry emergency supplies in your day bag

A small kit in your day bag can prevent a bad situation from becoming dangerous. Include:

• At least two liters of water or electrolyte drinks
• Salty snacks like pretzels or nuts to replace lost sodium
• A basic first aid kit with bandages and any personal medications
• A portable phone charger (heat drains batteries faster)
• A printed map or downloaded offline map (phones die faster in heat)
• Sunscreen with SPF 30 or higher, reapplied every two hours

This kit adds maybe a pound to your bag. The peace of mind and the actual safety benefit are worth every ounce.

Check the forecast before every outing

Weather in extreme heat zones can change quickly. A clear morning can turn into a humid, oppressive afternoon, or an unexpected thunderstorm can create dangerous flash flooding in dry areas like the American Southwest.

Before you leave your hotel each morning, check the hourly forecast. Look not just at the high temperature but at the humidity, which dramatically affects how hot it actually feels. A 95°F day with 80% humidity is far more dangerous than a 105°F day with 10% humidity.

Apps like Weather Underground or your phone’s built-in weather app give you hourly breakdowns that help you plan precisely.

Extreme heat does not have to ruin your travel plans. It just means you need to plan differently than you would for a mild-weather trip. The people who thrive in Phoenix, Las Vegas, and Mediterranean summers have spent years learning these lessons. You do not need years. You just need to follow the tips above and adjust your expectations to match the reality of the temperature.
