Planning what to wear in Switzerland in summer?
Swiss summer weather can be beautifully warm, but unpredictable- you might experience 25°C sunshine in Zurich and 10°C mountain chill on the same day. After 25 years of Swiss summers, I’ve learned that layers and versatility are key.
Quick Answer:
- Pack lightweight summer clothes (shorts, dresses, t-shirts), plus trousers
- Light jacket
- Comfortable walking shoes and hiking boots if visiting the mountains
- Swimwear for Switzerland’s famous Badi (public swimming) culture
- Layers are essential as temperatures vary dramatically between valley and mountains
This complete packing guide will help you prepare for Swiss cities, mountain villages, and everything in between, so you can focus on enjoying your trip instead of worrying about your wardrobe.
What to wear in Switzerland in summer: at a glance
| Where you’re going | Outfit | Layer | Shoes | Extras |
|---|---|---|---|---|
| City day (Zürich, Lucerne, Basel) | T-shirt or dress + shorts or skirt | Light cardigan for mornings | Sneakers or comfortable flats | Sunglasses, sun hat |
| Lake / Badi day | Swimsuit | Cover-up | Sandals or flip-flops | Towel, sunscreen, water shoes, waterproof bag |
| Mountain day trip | Quick-dry pants/leggings + moisture-wicking top | Fleece or light jacket | Trekking shoes or hiking boots | Rain jacket, sun hat, sunscreen |
| Summer hike | Quick-dry activewear + light layers | Rain jacket (always) | Hiking boots | Daypack, water bottle, hat, sunscreen |
| Evening dining | Smart-casual — jeans or dress + nice top | Light cardigan or jacket | Flats or sandals | It cools fast after sunset |
Local rule: Even in summer, always carry one light layer and a rain jacket. The mountains are always cooler, and afternoon storms appear without warning.
What to Wear Each Month
Swiss summer weather varies by month and by altitude, here’s what to expect and how to dress.
June
June is early summer, warm but not hot just yet. City temperature sit between 18-25°C (64-77°F) but mornings and evenings can still have you reaching for a light jacket. The mountains are cooler again, and some of the higher trails may still have snow. Pack a mix of summer clothes and a light jacket for the evenings. June is also when the Swiss Badi culture kicks off – the moment temperatures hit 25 °C every lake, river and pool fills ups. June days are long (sunrise is around 5.30am and sunset around 9pm), so you get more out of each day.
July
Peak summer! July, alongside August is the hottest month of the year. City temperatures regularly hit 28-32°C (82-90°F). Heatwaves above 30°C are common but usually last only a week. The majority of Swiss homes and restaurants don’t have air conditioning, so lightweight breathable clothing is essential. In the mountains, it’s cooler (15-22°C) but the sun can be really intense at higher altitudes – so sunscreen and a hat are non-negotiable. Afternoon thunderstorms are common and can appear, especially in the Alps, quickly so always carry a rain jacket, even on clear mornings.
August
Similar to July – August is hot in the cities and cooler in the mountains. August is peak holiday season in Switzerland and the Badis are packed. Towards the end of August you’ll notice evenings cooling with the first hints of autumn. If you’re hiking, this is prime season with trails fully open and conditions at their best. Pack mostly summer clothes but keep that light jacket handy for mountain days and outdoor dinners.
Weather Resources
Local weather apps are essential for planning your day, especially for finding those pauses between rain showers. I’ve written a detailed guide on the best weather apps for Switzerland that covers which apps locals actually use and how to read Swiss weather forecasts accurately. For quick checks, MeteoSwiss or Meteo Centrale are the most reliable Swiss-based forecasts.
LOCAL TIP: Swiss summer weather can really be mixed, so while the above is the best case scenario, there can be stretches of rainy, cooler periods in summer.
Complete Switzerland Summer Packing List
For the most part, all you will need for a Swiss summer are light summery outfits. Think tops and shorts, skirts and dresses made of light materials that breathe well. Swiss summers have been getting hotter – heatwaves above 30°C are now common at some point during the summer months. So pack accordingly.
Clothing Essentials
Tops & Layers
Pack breathable, lightweight layers that can be combined as temperatures shift throughout the day
-
- Light t-shirts and tank tops
- 1-2 long-sleeve shirts. The mornings can be chilly, especially in early summer or when the sun hides behind the clouds. You will be glad to have something to cover your arms. But keep it light.
- Light weight jumper, cardigan or fleece
- Lightweight jacket.
Bottoms
Switzerland is casual but practical. Versatile pieces work best.
-
- Shorts
- Long pants or jeans: I always pack a pair of long pants, especially in the mountains, even in summer. I really hope you won’t need them, but you will thank me for packing something warmer such as a pair of jeans or long pants for a random chilly day.
- Skirts or dresses
- Lightweight leggings
For Hiking/Mountains
-
- Quick dry activewear. Consider multi-purpose hiking pants that zip off into shorts. They really come into their own when the mornings start off cool and heats up by lunch. You will be grateful for the quick-dry material after a random rain storm.
- Moisture-wicking layers.
- Windproof/Water-proof jacket
Footwear Guide
As soon as the sun comes out, I love to kick off those socks and get straight into summer shoes. I mix it up between loafers, sandals and Birkenstocks on warm days. Ideally, when travelling Switzerland in summer you will need 2-3 pairs of shoes, especially if you plan to hike.
Comfortable walking shoes (essential)
-
- For: City exploring, flat terrain
- Options: shoes you can comfortably walk all day in like sneakers or flats
Hiking Shoes or Boots
-
- Sneakers? They are fine for the city, and easy hikes. But for mountain trails, wet or rocky terrain they won’t work.
- Trekking Shoes: for light hikes and stable trails
- Hiking Boots: for challenging hikes and ankle support
Casual Summer Shoes
-
- For casual evenings and trips to the Badi (swimming)
- Options: Sandals, flip-flops, Birkenstocks
Accessories & Extras
- Sunglasses (essential, the swiss sun is strong, especially at altitude)
- Sun hat
- Small backpack: is essential in summer – you’ll want it for your water bottle, rain jacket, sunscreen and storing that extra layer you will inevitably peel off by noon.
- Reusable water bottle
Swimming and Badi Essentials
Yes! Bring your swimming supplies. Switzerland may not be the first place you think of for a swimming holiday. But I promise you, there is an entire Badi culture in Switzerland and you will want to be a part of it.
But what is a Badi? Every Swiss town has at least one – a public swimming area on a lake, river or outdoor pool. From end of May till mid-September, the Badi is where Swiss social life happens. Families, friends and colleagues meet after work to swim, eat ice-cream and enjoy the long summer evenings. Don’t miss it – it’s one of the most authentic Swiss summer experiences you can have.
Badi Packing List:
- Swimsuit
- Quick dry towel
- Flip Flops or Water shoes (lakes can be rocky)
- Sunscreen
- Water-proof bag for your wet things
