18 July 2026

Discovering St. Gallen: When Should You Visit?

St. Gallen is one of the most charming cities in eastern Switzerland – with a magnificent old town, the world-famous Abbey District, and a vibrant cultural scene. Whether you're planning a weekend getaway or a full week away, choosing the right time to travel can make all the difference to your stay. In this travel guide, you'll find everything you need to know for your trip to St. Gallen in 2025.

Spring in St. Gallen (March to May)

Spring is one of the most beautiful seasons in St. Gallen. Temperatures gradually rise to a pleasant 10 to 18 degrees, nature awakens, and the old town bursts into fresh colours. This period is ideal for strolling through the picturesque lanes around the Abbey Church and the Cathedral.

  • Spring highlights: Blossoms in the city park, the first terrace cafés opening in the city centre
  • Fewer tourists than in summer – a more relaxed travel experience
  • Perfect conditions for day trips into the surrounding Appenzell countryside

Those who prefer lower accommodation prices and a peaceful atmosphere will find spring just right. Book your holiday apartment early and directly to secure the best availability.

Summer in St. Gallen (June to August)

Summer is the peak season in St. Gallen – and for good reason. With temperatures between 20 and 28 degrees, the city offers ideal conditions for outdoor activities, leisurely city strolls, and cultural events.

The St. Gallen Open Air Festival

The St. Gallen Open Air, one of Switzerland's oldest music festivals, traditionally takes place at the end of June and draws tens of thousands of music lovers every year. 2025 promises another unforgettable line-up. Anyone wishing to stay in the city during the festival should book well in advance – accommodation is in high demand at this time.

  • St. Gallen Open Air: late June 2025
  • City festival and summer markets in the city centre
  • Day trips to Lake Constance or the Appenzell Alps

A private holiday apartment in St. Gallen offers you more flexibility in summer than a traditional hotel – with your own living area, kitchen, and a personal atmosphere.

Autumn in St. Gallen (September to November)

Autumn casts a spell over St. Gallen with golden hues and a distinctive quality of light. Temperatures range between 8 and 17 degrees – perfect for active exploration of the surrounding nature. Hiking through the Appenzell Vorderland is an absolute highlight at this time of year.

  • Golden autumn landscapes around St. Gallen
  • Regional wine festivals and culinary events
  • Visiting the Abbey Library without the stress of peak season

The Abbey Library of St. Gallen – a UNESCO World Heritage Site – is wonderfully peaceful in autumn and can be enjoyed to the fullest without the crowds. For culture enthusiasts, autumn is one of the very best times of year to visit.

Winter in St. Gallen (December to February)

Visiting St. Gallen in winter means experiencing a city full of magic. December brings Christmas markets, festive lighting throughout the old town, and cosy hours spent in the city's many cafés and restaurants.

Christmas Magic in the Old Town

The Christmas market around the Cathedral is considered one of the most beautiful in Switzerland. Mulled wine, artisan crafts, and festive music create a truly unique atmosphere. Winter sports enthusiasts are also well catered for: the Appenzell mountains are just a short journey away.

  • Atmospheric Christmas market in the old town (November to December)
  • Winter sports in the nearby Appenzell region
  • Peaceful atmosphere after the holidays – ideal for unwinding

The winter months of January and February are the quietest time to travel – ideal for anyone who wants to experience St. Gallen without the tourists and at attractive prices.
