How to Survive the Heat in Europe — and in Budapest
By Kata | katabudapest.com | Published Jun 25, 2026
Every summer it seems to get a little hotter here, and 2026 has been no exception. As I write this, Hungary is under a third-degree heat alert (our highest level), with daytime highs of 35–41°C / 95–106°F forecast across the country. Western Europe has been even more brutal — Spain, Portugal and France pushing past 40°C for days on end.
I've been guiding visitors around Budapest for over a decade, and I've watched far too many travellers arrive in flip-flops with no water and no plan, only to spend the afternoon feeling miserable instead of enjoying my beautiful city. So let me share the advice I give my own guests. None of it is complicated — but together it makes the difference between a holiday you love and one you survive.
First things first: book accommodation with real air conditioning
This is the one I cannot stress enough. Many European apartments and older hotels simply don't have air conditioning, because for most of our history we never needed it. That's changing fast, but the buildings haven't caught up.
When you book an Airbnb or hotel, don't just trust the listing — message the host and ask directly whether the AC works and how cold the room actually gets. A ceiling fan is not air conditioning. After a 38°C day, you need somewhere your body can genuinely recover overnight, because the heat that harms people most is the heat trapped indoors that never lets you cool down.
Hydrate — and I mean properly
Drink water constantly, before you feel thirsty. Carry a refillable bottle everywhere. The good news in Budapest: our tap water is excellent and safe to drink, so you can fill up anywhere for free. You'll also find public drinking fountains around the city, and during this heatwave the Hungarian railway company (MÁV) has even been handing out free bottled water at the main stations.
Don't forget your electrolytes
Here's the part people miss: when it's this hot and you're sweating all day, plain water isn't quite enough. You lose salts too, and that's what leaves you headachy and drained by evening. Pack a few electrolyte sachets (the ones you drop into water) or pick some up at any Hungarian pharmacy — ask for "izotóniás italpor" or rehydration salts. One in the morning and one in the afternoon works wonders.
Wear a hat — a real one
A proper wide-brimmed hat, not just sunglasses. It shades your face and neck and keeps your head measurably cooler. Light, loose, breathable clothing in pale colours helps too. You'll see locals dressed this way for a reason.

Let's explore Budapest →Don't skimp on sunscreen
It's easy to focus on the heat and forget the burn, but our UV levels in a heatwave are rated "very high." Use SPF 30–50 and reapply it every couple of hours — especially down by the river or on a boat, where there's no shade at all. Proper sunglasses with UV protection are worth packing too.
Bring an electric hand fan
This little gadget has become my favourite summer travel hack, and my guests always end up wanting one. A small rechargeable electric hand fan fits in your bag and gives you instant relief while you're waiting for a tram, queuing for a museum, or sitting at a café terrace. Inexpensive, light, and genuinely lovely on a sticky afternoon.
Plan your day around the sun
This is where a little local rhythm goes a long way:
Start early. The light is gorgeous, the streets are quiet, and the temperature is bearable. I always schedule my walking tours for the morning in high summer — by 9am the Castle District is magical and not yet an oven.
Hide during the worst hours. Our meteorological service advises staying out of direct sun between 11am and 3pm, and honestly I'd stretch that to 4pm on the hottest days. Use that window for an air-conditioned museum, a long lunch indoors, or a rest at your hotel.
Come back out in the evening. Budapest comes alive again after the sun softens. A Danube riverside stroll at dusk, with the Parliament lighting up, is one of the best things you'll do here.
Escape underground at midday
Here's a local trick most visitors never think of: go under the city. Places like the Hospital in the Rock, the Buda Castle Labyrinth, and the Pálvölgy and Szemlőhegy caves stay naturally cool — often 10–20°C — no matter how brutal it is up top. They're genuinely fascinating, and a perfect way to spend the hottest hours of the day without melting.
Skip the alcohol while the sun is up
I know, I know — Hungary has wonderful wine, and everyone wants to try pálinka. But alcohol dehydrates you, and in extreme heat that's a fast track to feeling awful or worse. Save the wine and pálinka for the cooler evening hours, with plenty of water alongside. Your body (and the next morning) will thank you.
Eat light — and try our cold cherry soup
Heavy meals make you feel the heat even more, so go lighter than usual during the day — salads, fruit, cold dishes. And here's the perfectly Hungarian way to cool down from the inside: hideg meggyleves, our chilled sour cherry soup. It's creamy, sweet-tart and served cold, and on a sweltering afternoon it's pure bliss. Order it whenever you spot it on a summer menu.
Please don't swim in random rivers
Every summer, tragically, people drown trying to cool off in the Danube or other rivers and lakes. The Danube looks calm but has strong, deceptive currents and cold undertows — it is not a swimming spot, no matter how tempting. If you want to swim, go to a proper lido (strand), a public pool, or one of our supervised thermal baths. Speaking of which…
A Budapest secret: the heat is the perfect excuse for a thermal bath
Don't think of our famous baths as a winter thing. On a scorching day, Széchenyi or Lukács with their shaded areas and cooler pools are a genuine refuge — and far safer than any river. It's the most Budapest way imaginable to beat the heat.
Or just head for the water
When the city feels like an oven, sometimes the best thing to do is get out of it. A few of my favourite ways to cool off properly:
Make a day trip to Lake Balaton. Central Europe's largest lake is only a couple of hours away, and on a hot day there's nothing better — gentle, shallow, sun-warmed water, lakeside towns, good wine on the hillsides, and a completely different pace from the city. It's the classic Hungarian summer escape. If you'd like to go, I'm very happy to help you organise it — the right town for what you're after, how to get there, and what to see along the way.
Palatinus Strand on Margaret Island. Right in the centre, set in the island's greenery, this big open-air complex was once voted among the world's most beautiful outdoor pools. Lots of pools, slides and shaded lawns — perfect for families and an easy afternoon escape. Open daily through the summer, and a short hop on tram 4 or 6 to the Margitsziget stop.
Lupa Beach — Budapest's "seaside." About 20 minutes north of the city, Lupa is a proper sandy beach with palm trees and clear lake water you can actually swim in safely. SUP, paddleboards, beach bars, the works. It's the closest thing we have to the coast, and a lovely way to spend a sweltering day.
Good news about getting around Budapest
One worry off your list: most of our public transport is air conditioned. The newer metro trains, trams and buses keep you cool between stops, so you can cross the city in comfort. The metro tunnels themselves stay refreshingly cool too. Just check the vehicle before you board on the very hottest days — the oldest carriages can still be warm.
Walk through the misting gates
During heat alerts, the city puts up misting gates at busy squares and transport hubs — arches that spray a fine, cool mist as you pass through. Most tourists walk right past without realising what they are. Keep an eye out and stroll through one; it's a tiny moment of instant relief on a baking day.
Know when to stop
Finally, please listen to your body. Dizziness, a pounding headache, nausea, or suddenly stopping sweating are warning signs of heat exhaustion — and they mean it's time to get into shade, cool down and rehydrate right away. Don't try to push through it to see one more sight. Budapest will still be here tomorrow, and I'd much rather you saw it feeling well.
