Is August Right for You?
Weigh the advantages and considerations before booking
Advantages
- + August alpine lakes hit 20°C (68°F). Warm enough to swim in Lake Thun and Brienz without turning blue. Jump in. The cold shock never comes.
- + Paragliding thermals are strongest now. Flights stretch 30-45 minutes instead of the usual 15-20. You stay airborne twice as long. Book early.
- + Mountain huts keep full kitchens open through August. Hike hut-to-hut without carrying food. Just bring appetite. The rösti tastes better at altitude.
- + The Harderbahn funicular runs until 10:30pm. Winter shuts down at 7pm. Catch sunset from Harder Kulm at 8:45pm. The sky burns orange over the lake.
Considerations
- − The Jungfraujoch railway will be packed. August sees 7,000 daily visitors versus 2,000 in May. Queue early. Or skip it.
- − Afternoon thunderstorms roll in around 3pm 40% of days. Summit plans die after lunch. Start early. Be below tree line by 2pm.
- − Hotel rates jump to peak pricing. What costs CHF 180 in April hits CHF 280-320 for the same room. Same bed. Different season.
Best Activities in August
Top things to do during your visit
In Interlaken, August air is thick with the scent of pine resin and the damp earth that follows a mountain shower, a common occurrence in a month that sees more rainfall than any other time of year. The days are long, with temperatures often reaching the mid-seventies, inviting the clatter of hiking boots on cobblestones and the distant roar of glacial waterfalls at their most powerful. This is a month of contrasts in Interlaken, where mornings can dawn under a clear cerulean sky, only to give way to afternoon clouds that wrap around the peaks of the Jungfrau, creating a shifting, dramatic tableau. While no major festivals define the calendar, the rhythm is set by the steady flow of visitors exploring the town's emerald parks and the locals making the most of the reliable warmth before the crisp turn of autumn. Compared to the deep freeze of January, when highs barely crest freezing, August in Interlaken feels lush and alive, a peak season defined by verdant trails and the occasional taste of cool rain on the breeze.

August Events & Festivals
What's happening during your visit
Early August
Interlaken International Street Artists Festival
Acrobats, jugglers and fire-eaters take over Höhematte Park for four days. The 6pm shows are free. The 9pm 'Night of Stars' ticketed performance sells out. Local tip: bring a picnic blanket. The grass gets dew-soaked after 8pm even in August.
Late August
Jungfrau Marathon
Runners climb 1,823m (5,981 ft) from Interlaken to the Eigergletscher station. It's the world's most beautiful marathon route. Even if you're not running, the 8am start creates a human snake up the mountain. Watch from the train window. The view beats any seat in the house.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The 6:13am train to Lauterbrunnen is filled with cleaners and hotel staff. It's half-empty compared to the 7:13am tourist train. You get the same early-mountain advantage. Quieter too.
August 15 is Swiss National Day (observed). Everything closes except tourist attractions. Fireworks over Lake Thun from Höhematte are better than Geneva's. Bring a jacket. The show starts late.
Coop supermarket at Interlaken West station marks down sandwiches after 6pm. Good for next-day hiking lunches. Stock up. Save francs.
The free 'Guest Card' from your hotel gives you 10% off cable cars after 3pm. August's afternoon storms make this the smart time to go up anyway. Double win.
Avoid These Mistakes
Booking Jungfraujoch for midday. Go before 9am or after 4pm to avoid the 2-hour queue at the top station. Midday crowds crush. Early or late wins.
Wearing cotton t-shirts hiking. August humidity hits 70%. You'll be soaked with sweat AND rain by lunchtime. Cotton kills. Avoid it.
Planning outdoor activities after 2pm. Lightning risk peaks 3-5pm when storms build over the peaks. The mountains don't care. You lose.
Ignoring the 'last cable car down' times. August evenings stretch late but some routes stop at 5:30pm. Stranded hikers sleep in huts. Or worse.
