Be prepared for any unpredictability the weather may bring during your visit. Below you will find detailed information about the current weather in Rorschach, along with up-to-date forecasts and charts.

There are no extreme heatwaves or excessively harsh frosts here, making the city a comfortable destination for travelers at any time of year. Overall, the weather is characterized by its mildness, though you should be prepared for frequent cloud cover and precipitation, which are distributed fairly evenly across the seasons.

Summers in the city are pleasant and never too hot: in July and August, the average temperature stays around +19°C, while daytime highs reach a comfortable +23°C, perfect for strolls along the promenade. Winters here are cool but not freezing; the thermometer often hovers around zero or drops slightly below, creating the typical atmosphere of the Swiss foothills.

An important feature of Rorschach's weather is the significant number of rainy days throughout the year. Even during the warmest season, from May to August, rain is a frequent occurrence (up to 18–19 rainy days per month). Tourists are advised to always have an umbrella or a raincoat handy, as clear skies can quickly turn to rain regardless of the month you choose for your trip.

The temperature regime in Rorschach is characterized by moderation and smooth transitions between seasons, which is typical for the Lake Constance region. The coldest time of year is winter, especially January, when the average temperature drops to 0.8°C. In the winter months, including December and February, the weather is quite cool: night frosts average -2°C, but during the day, the air often warms up to positive values ranging from 3°C to 6°C, making the winter here mild and tolerable.

Summers in the city offer comfortable warmth without extreme heat. The hottest month is July, with an average temperature of 19.0°C and daytime highs around 23.1°C; August is nearly identical. This time is ideal for walking and relaxing by the water, as the weather is pleasantly warm. However, even in the height of summer, nights bring a certain freshness: temperatures after dark usually drop to 14–15°C, so a light jacket might be useful for evening promenades.

Spring and autumn show a gradual change in climate. By May, average figures reach 12.5°C, and in October, they stay around 11.2°C before a noticeable cooling begins. Throughout the year, there is a moderate difference between daytime and nighttime temperatures, averaging 4–8 degrees. These fluctuations are not sharp, but tourists are advised to take them into account when planning their wardrobe for long excursions.

Precipitation in Rorschach is distributed fairly evenly throughout the year, so there is no clearly defined dry season. The proximity of Lake Constance influences the climate, keeping humidity at a stable level. Travelers should be prepared for the fact that an umbrella or waterproof clothing may be needed in almost any month of the trip.

The highest frequency of precipitation is recorded in late spring and the first half of summer. The record holder for the number of rainy days is May, when it can rain for about 19 days of the month. The summer period also remains quite wet: June and July see between 17 and 18 rainy days, while August leads in terms of total rainfall volume, which may indicate more intense summer downpours.

In winter, especially in December and January, the nature of precipitation changes. Due to lower temperatures (averaging around 0°C to 1.5°C), rain often gives way to snowfall. December, for instance, is characterized by high cloudiness, with precipitation falling on average for 18 days. Even in the "driest" months of the year, such as February and April, statistics show about 13 days of precipitation, so the possibility of rain or snow can never be completely ruled out.

The weather in Rorschach, located on the shores of Lake Constance, can be changeable, so layering is the universal solution for any season. Even in summer, sweltering heat is rare (average temperatures hover around +19°C), and a fresh breeze often blows from the lake. Therefore, in addition to T-shirts and light shirts, be sure to pack a cozy sweater, cardigan, or fleece jacket that you can easily put on or take off as the weather shifts. Comfortable shoes for long walks along the promenade are an absolute must-have.

If your trip is planned for the period from November to March, prepare for cool days: temperatures stay just above freezing, but high humidity can make it feel much colder. You will need a warm, windproof jacket, a hat, a scarf, and gloves. In summer, sunglasses and sunscreen will come in handy, as the sun by the water can be very intense. Don't forget your swimwear if you plan to visit the famous Badhütte bathing hut during the warmer months.

Special attention should be paid to rain protection. Statistics show that rainy days in Rorschach occur quite frequently throughout the year (averaging 13–19 days per month), even if the total rainfall isn't always high. Therefore, a compact umbrella or a high-quality raincoat should be in your luggage regardless of the season. A hooded windbreaker is the ideal companion for spring and autumn walks, protecting you from both the lake breeze and sudden drizzle.
