While it’s one of the most popular travel destinations in the world, Europe’s summer heatwaves have become a challenge, with temperatures often going well over 40°C (104°F).
The European heatwaves of 2003 and 2019 serve as reminders of their deadly potential, with thousands affected by heatstroke, dehydration, and heart complications.

Why Summer Heat in Europe Catches Travelers Off Guard
For many travelers, especially those from North America, the intensity of European heat is surprising for one main reason: air conditioning is not as common.
Unlike in the US, where central air is standard in most homes, shops, and public spaces, many European buildings were constructed long before AC was invented. This means you may find that older hotels, apartments, restaurants, and even some public transport systems lack effective air conditioning.
This cultural and infrastructural difference is key. Travelers often expect to find relief indoors, only to discover that indoor spaces can be just as warm as outside. This makes it much harder for your body to cool down and recover after a long day of sightseeing, which is why proactive planning is so important.
Heatwaves In Europe Aren’t A Joke!
Heatwaves in Europe don’t just leave you feeling sweaty and irritated. They can be dangerous. Europe has seen some serious heatwaves in the past – let’s take a quick look at a timeline of some of Europe’s heatwaves.
The History Of Heatwaves In Europe
Europe has seen some intense heatwaves in the past 20 years.
- 2003: July – August
The heatwave of 2003 saw western Europe reaching its highest temperatures since at least the year 1540. A total of 72,000 heat-related deaths were recorded during this time. The peak temperature recorded was 47.3°C (117.1°F).
- 2006: June – July
The 2006 European heat wave reached temperatures as high as 42°C (107.6°F) throughout western Europe. A total of 3,418 heat-related deaths were recorded in just over a month.
- 2007: June – August
Mainly affecting southern Europe, the 2007 heatwave saw a peak temperature of 47.5°C (117.5°F). Over 500 deaths were recorded in Hungary, and there were major wildfires during this time. The cost of the heat wave was estimated to be around 2 million Euros.
- 2018: April – May; June – September
The heatwaves of 2018 affected many parts of central and northern Europe throughout its spring and summer seasons. A peak of 46.8°C (116.2°F) was recorded. While there’s no official toll for lives lost, the fact that freshwater fish were dying is a good indication that this heatwave (and the drought it caused) wasn’t a joke.
- 2019: June – July
Spiking at temperatures as high as 46.0°C (114.8°F), the heatwave of 2019 was so intense that Britain’s Network Rail had to impose speed restrictions because the train tracks were buckling because of the heat. A total of 3,951+ heat-related deaths were recorded.
- 2022: June – September
From June to September of 2022, persistent heatwaves made their way across Europe. The peak temperature recorded was 47.0°C (116.6°F), with over 20,000 heat-related deaths being logged.
- 2024: June – August
Since June of 2024, there have been heat waves across Europe. The peak temperature was logged at 45.7°C (114.3°F), and a total of 19 deaths were recorded.
- 2025: June – August
Southern Europe, particularly Greece and Italy, saw record-breaking tourist numbers during extreme heat alerts, leading to hundreds of emergency calls daily.
Who Needs To Be Extra Careful?
While the heatwaves are dangerous in general, there are a few groups that should be extra careful.
- Pregnant Travelers: Your body’s already working hard, so extra heat can only add to the stress.
- Elderly Travelers: As your body gets older, your ability to regulate temperature decreases. That means that the elderly are more likely to experience heatstroke.
- Travelers with Pre-existing Conditions: Conditions such as asthma, heart disease, and diabetes can worsen in extreme heats.
- Children and Babies: They are more vulnerable to heat because their bodies have more trouble regulating temperature. They can also become dehydrated much faster than adults.
Signs You Should Look Out For
There are a couple of symptoms you can look out for that may indicate a heatstroke or heat exhaustion may happen:
- Dizziness
- Light-headedness
- Headaches
- Fatigue
- Weakness
- Rapid heartbeat
- Muscle cramps

How To Stay Safe
When you’re traveling in Europe, there are some things you can do to keep cool, calm, and safe!
- Stay Hydrated: This might seem obvious, but it’s easy to forget to drink enough water when you’re out exploring. Carry a reusable water bottle and sip regularly. Avoid alcohol, as it can dehydrate you quickly.
- Take Advantage of Cool Spots: Whether it’s ducking into a museum, café, or even a park with lots of shade, give yourself breaks from the sun, especially between 11 AM and 4 PM when the heat is most intense.
- Dress Smart: Loose, lightweight, and light-colored clothing is key. Opt for breathable fabrics like cotton or linen, and don’t forget your sunscreen, a wide-brimmed hat, and sunglasses to protect from harmful UV rays.
- Monitor the Weather: Make sure to check the forecast daily so you’re aware of any heat warnings. It’s also helpful to know if your destination has air-conditioned spaces available, like restaurants, shopping centers, and public buildings, where you can cool off.
- Use Fans: Small portable fans can make a huge difference, and really help you stay cool – especially if you’re traveling on foot.
- Eat Light Foods: Avoid heavy meals, and opt to go for things like fruits, salads, and chilled snacks to keep your body cool.
How To Get Help During A Heatwave
As you plan your travel for the summer of 2026, it’s wise to keep the reality of Europe’s climate in mind. Building a flexible itinerary that allows for slow, cool afternoons can make your trip safer and more enjoyable.
If you ever feel unwell or notice unusual symptoms while traveling in the heat, it’s important to find a cool place, hydrate immediately, and rest. If your symptoms don’t improve, it’s best to see a doctor.
In Short
Traveling in Europe during a heatwave requires more than just a hat and sunscreen. Here are the key things to remember:
- Heat in Europe can feel more intense because air conditioning is not widespread.
- Vulnerable groups include the elderly, children, pregnant travelers, and those with pre-existing health conditions.
- Key symptoms of heat exhaustion include dizziness, headaches, and rapid heartbeat.
- Stay hydrated, seek out cool spots during the hottest part of the day, and wear light clothing.
- Plan your sightseeing for early mornings or evenings to avoid peak sun.
- Listen to your body and don’t push yourself on extremely hot days.

FAQs
July and August are typically the hottest months across most of Europe, especially in the southern and western regions. This is also peak tourist season, which can make dealing with the heat more challenging.
Not as common as in many other parts of the world. While modern hotels and large department stores usually have it, many smaller hotels, restaurants, and public transport systems do not. It’s always a good idea to check your accommodation’s amenities before booking.
Southern European countries like Spain, Italy, Greece, and Portugal are often the most affected by extreme summer heat. However, in recent years, heatwaves have become more common in Western and even Northern Europe, including France, Germany, and the UK.
