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
August in Interlaken smells of damp pine after a morning shower. Steam rises from wet cobblestones. The air shifts between a 74-degree afternoon and a 56-degree evening, so pack layers. Locals know the meadows are at their most brilliant green now. The town pulses with energy. This is clearest during the Interlaken International Street Artists Festival. Höhematte Park fills with the crackle of fire props and gasps for acrobats on dew-slicked grass. Later, the Jungfrau Marathon sends a stream of runners up the mountainside. Watch them from a train carriage, a human thread against the stone and ice. This is Interlaken at its peak. The Alps are a backdrop for human try.
Snowshoe Adventure in the Swiss Alps
otheroffers profound quiet. You must step off the summer trails onto a high-altitude snowfield. You will hear your footsteps crunch on granular August snow. The thin, sharp air hits your throat. The panorama of rock and ice feels removed from the green valleys below.
It is a rare chance to experience alpine winter's stillness in summer. This contrast defines the Bernese Oberland.
Insider tip: Wear sunglasses with full UV protection. The August sun on snow is intensely bright, even on cool days.
This month: Reliable snow in August depends on specific, elevated locations and current conditions.
Interlaken Valley Winter E-Bike Tour: Rivers, Lakes & Castles

Grindelwald -Kleine Scheidegg-Lauterbrunnen Small Group Day Trip

Scenic E Bike Tour Interlaken
adventureis defined by cool breeze from your own motion. You roll through farmland, forest, and lake shore. See the brilliant blue of Lake Thun framed by snow-dusted peaks. Hear the hum of the bike's motor on a gentle incline. Feel sun-warmed wooden planks of a covered bridge beneath your tires.

Discover Interlaken's most Photogenic Spots with a Local
othermoves beyond postcard stands. Find light on a frescoed hotel facade. See a church spire align with the Harder Kulm summit.

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.
