Europe's summer heat has grown more intense in recent years — in southern Spain, Italy and Greece the temperature often reaches 38-42°C. If you travel in July-August, a heatwave seriously changes the rhythm of your holiday: wandering outdoors in the midday hours drains you and can even be dangerous. This guide tells you how to plan your day, what to wear and how to protect your health so the heat doesn't ruin your trip.
🕗 Plan the day around the heat
In southern Europe locals have long known it: the hottest period is 12:00-17:00. During those hours they rest indoors, in the shade or at home (the siesta). The same logic works for you — see the sights early in the morning (08:00-11:00) or in the evening (after 18:00), when it's hot but bearable.
Give the midday to a shaded activity: a museum, a gallery or an air-conditioned café. To avoid queues, book tickets in advance — see the skip-the-line guide.
The first slot of the day at an attraction is a double win: fewer people and still-cool air. In the evening the city comes alive — that's exactly when locals stroll.
💧 Water and protecting your body
In the heat the body loses far more fluid. Drink water regularly, before you feel thirsty — 2-3 liters a day is normal for an active day. Many European cities (Rome, Barcelona, Vienna) have free public fountains with drinking water — carry a reusable bottle and refill it.
Tap water safety varies by country — see the Europe tap water guide. A small travel first-aid kit also helps: electrolytes, sunscreen and salted water for exhaustion.
The signs of heatstroke — dizziness, nausea, stopping sweating and confusion — should never be ignored. If they appear, move to the shade immediately, wet yourself and drink water; if it worsens, see a doctor.
👕 What to wear and pack
- Light-colored, thin cotton or linen clothing — synthetics are bad in the heat
- A wide-brimmed hat and UV-protection sunglasses
- Sunscreen SPF 30+ — reapply every 2-3 hours
- Comfortable, breathable shoes — there are lots of cobblestone streets
- A reusable water bottle and a small fan
- A power bank — in hot weather a phone battery drains fast
🏖️ Where to go to escape the heat
If the heat crosses the bearable line, shift your route toward the sea or the north. On the coasts of Spain, Italy and Greece the breeze softens the temperature — for ideas, see the Europe beach destinations guide. Alpine regions and northern Europe (Scandinavia) are much cooler in summer.
When planning, remember a heatwave affects transport too — trains sometimes slow down, and air conditioning isn't perfect everywhere. For internet, get an eSIM on arrival so the weather forecast and maps are at hand.
💡 Summary
- Rest in the shade 12:00-17:00; sightsee in the morning or evening
