How to stay safe while traveling during extreme heat

As travelers prepare to set off on summer trips, scorching temperatures lie in wait. Above-average temperatures could be on the books this summer, according to forecasters, and a developing El Niño event could spell out warmer weather later in the year or next summer.

“The same way that we prepare for more extreme travel in the cold, we should start to consider those tips to keep us safe in the summer months,” says Dr. Alexander Azan, who is with NYU Langone Health and co-directs the Project Heatwave initiative.

Check the forecast and survey your travel companions

Before taking off, check the air temperatures for both day and night as well as the heat index, which takes humidity into account, Azan says.

If temperatures look scorching, stay flexible. Plan more strenuous outdoor activities like hiking or long walks during early morning or late evening hours, outside of peak heat windows. A midday movie, museum visit, or coffee shop break may be more suitable.

In addition to what you’re bringing, think about who you’re bringing. People with certain medical conditions or medications may be more vulnerable to heat while traveling.

Older adults, those who may be pregnant, young children, and infants are also especially susceptible—so adjust plans accordingly. Carrying a baby against your body can transfer additional heat, for example.

Pack a reusable water bottle and bring light-colored, breathable clothing that will keep you cool. Don’t forget sunscreen, sunglasses, a wide-brimmed hat, and a cooling towel. A portable fan can be useful too, but avoid using it during particularly high temperatures since it’ll just blow hot air back at you.

Keep car safety in mind during road trips

If you’re planning a road trip, get your vehicle inspected a few weeks before to make sure everything is in good condition, especially the engine cooling system and the car battery.

Pack water and snacks to keep passengers and pets energized during the drive and take breaks to hydrate and stretch—but don’t leave young children, pets, or older adults alone in the car even for a few minutes.

Keep the car as cool as possible by parking in shaded areas and using a windshield protector. When entering a steamy car, turn on the air conditioning but turn off recirculation to keep stale air from cycling. Roll down the windows a bit, then close them and turn recirculation on once the car starts to chill.

Stay flexible and recognize signs of heat illness

Travelers should be mindful of how their behavior changes on vacation. Spending long hours outdoors, participating in intense activities, or consuming more alcohol than usual can increase heat-related risks.

People often get into trouble when they ignore both environmental conditions and the warning signals their bodies are giving them. “They think they can push through. That is a mistake,” Ward says.

Look out for signs of heat illness like feeling dizzy, experiencing nausea or muscle cramps, and sweating with cool and clammy skin. If you start to feel sick, get to a shaded area and take sips of water while loosening tight clothing.

If symptoms worsen to slurred speech, falling unconscious, extreme confusion, or feeling hot to the touch, seek help immediately. That could indicate something more serious, like heat stroke.

By staying aware, taking steps to cool down, and adjusting plans where necessary, travelers can help ensure their trip remains both safe and enjoyable.
