🥵 How to Survive a Heatwave on Vacation: 10 Tips to Stay Cool When It Gets Hot
You've saved for months and looked forward to your sunny Mediterranean holiday. But then the news breaks: a heatwave is rolling across Europe, with temperatures of 40°C (104°F) and beyond. Your dream vacation is in danger of turning into a sweaty ordeal. But don't worry: with the right strategy, you can master even extreme heat, stay safe, and still enjoy your holiday.
Forget the heat stress. This guide is your personal survival plan. We give you 10 field-tested tips—from preparation to on-site behavior and recognizing danger signs.
Preparation is Everything: What to Do Before You Travel
1. Choose Your Accommodation Wisely
You can lay the groundwork for a cool vacation right from the booking stage. A functioning air conditioner in your hotel room or holiday apartment is no longer a luxury but a necessity when traveling to Southern Europe in high summer. Read other guests' reviews carefully. Accommodation with a pool offers a welcome opportunity to cool off.
2. Pack Smart
Your clothing is your personal cooling system. Focus on:
- Light, loose-fitting clothing: Tight clothes prevent air circulation. Loose trousers, dresses, and shirts allow air to circulate.
- Light colors: White, beige, and pastel tones reflect sunlight, while black and dark colors absorb it and heat up.
- Natural fabrics: Linen and cotton are more breathable than synthetic fabrics like polyester.
- Indispensable: A wide-brimmed sun hat, good sunglasses with UV protection, and high-SPF sunscreen (SPF 50+).
The On-Site Survival Strategy: Live Like a Local
3. The Golden Rule: Live by the Rhythm of the Siesta
Do as the southerners do: adapt your daily routine to the heat. The day is divided into two active phases, interrupted by a long midday break.
The Perfect Heatwave Daily Plan:
- Early Morning (7-11 AM): Your main activity time. Go for a swim now, visit the sights, or do your shopping. The air is still fresh, the sun not yet so strong.
- Midday Heat (11 AM - 5 PM): Retreat. This is the time for a siesta in the cool hotel room, a long, leisurely lunch in the shade, or a visit to an air-conditioned museum. Avoid any physical exertion in the blazing sun.
- Late Afternoon & Evening (from 5 PM): When the most intense heat has passed, the second part of the day begins. Perfect for a city stroll, an aperitivo on the beach, or a late dinner outdoors.
4. Drink, Drink, Drink! (But the Right Things)
Dehydration is the biggest danger in the heat. Your body loses a lot of fluid and important minerals through sweating.
- Water is King: Drink regularly throughout the day, even if you don't feel thirsty. At least 2-3 liters are a must.
- What to Avoid: Ice-cold drinks can shock the stomach. Alcohol and heavily sugared drinks dehydrate the body further.
- The Electrolyte Trick: Add a pinch of salt and a splash of lemon juice to your water, or use electrolyte powder from the pharmacy to replace the minerals lost through sweat. This helps against headaches and fatigue.
5. Eat Light and Fresh
A heavy, greasy meal forces your body to do extra digestive work, which raises your internal temperature. Opt for Mediterranean cuisine: salads, fruit (especially water-rich types like watermelon or cucumber), grilled fish, and vegetables are ideal.
6. Create Your Own Cool Oasis
Keep your hotel room or holiday apartment cool.
- Darken during the day: Close curtains and blinds to block solar radiation.
- Ventilate at night: Use the cool night air to air out the apartment.
- The Towel Trick: A damp towel hung in front of an open window or a fan cools the incoming air through evaporative cooling.
7. Cooling is Everything
Take every opportunity to cool down. A lukewarm (not ice-cold) shower in between works wonders. Hold your wrists under cold water or place a damp cloth on your neck—this cools the whole body.
Know the Danger Signs: Safety First
8. Recognize the Signs of Heat Exhaustion
Heat exhaustion is a warning sign from your body that it's overloaded. The symptoms are:
- Heavy sweating, pale and cool skin
- Weakness, dizziness, headache
- Nausea or vomiting
What to do? Immediately get into the shade or a cool room. Lie down, elevate your legs. Drink plenty of water in small sips. Place cool, wet cloths on your forehead and neck. If it doesn't get better quickly, see a doctor.
9. Heatstroke is a Medical Emergency!
A heatstroke is life-threatening and requires immediate action.
Symptoms: Very high body temperature (over 40°C / 104°F), bright red, hot, and dry skin (the body has stopped sweating!), confusion, rapid pulse, possible loss of consciousness.
What to do? Immediately call emergency services (112 in Europe)! Move the person to the shade immediately, remove clothing, and cool the body with wet cloths until help arrives.
10. Plan B: Find the Cool Places
If outdoor sightseeing becomes impossible, adapt your plans. Every city offers cool alternatives:
- Air-conditioned museums, galleries, or aquariums
- Cool, old churches and cathedrals
- An afternoon at the cinema
- An underground tour (catacombs, caves)
Conclusion
A heatwave doesn't have to ruin your vacation. By adapting your rhythm, listening to your body, and treating the heat with respect, you can stay safe and still enjoy the trip. It's about working with the weather, not against it. A quick, daily look at the hourly weather forecast will help you make the most of the coolest hours of the day.
