Winters here are cool but not freezing, with temperatures ranging from a slight "minus" at night to low positive values during the day.

An important feature of the local climate is the regularity of precipitation throughout the year. There are practically no dry months here: the number of rainy (or snowy in winter) days varies from 12 to 19 per month, with May and December often being the wettest periods. Travellers are advised to always carry an umbrella or raincoat, as variable cloudiness and precipitation are common occurrences for Altenrhein.

Winter months here are truly invigorating, yet without extreme frosts. The coldest month is traditionally January, when the average temperature drops to 0.6°C, and night-time readings can reach -2.5°C. February and December maintain this cool trend, creating the atmosphere of a typical Alpine winter, although daytime temperatures often rise slightly above zero, making walks quite comfortable with warm clothing.

The summer season in this region of Switzerland can be characterized as exceptionally pleasant and mild.

At this time, the air warms up during the day to a comfortable 23°C, which excludes exhausting heat and humidity. June also delights with warmth, with highs around 22°C. Such weather is perfect for outdoor activities and excursions, as moderate, refreshing warmth prevails here rather than dry heat.

It is also worth noting the characteristic daily temperature fluctuations observed throughout the year. The difference between daily highs and nightly lows usually ranges from 4 to 9 degrees. For example, in spring-like April, the air can warm up to 13.4°C during the day and cool down to 3.8°C at night. Therefore, when planning a trip to Altenrhein even in the warm months, it is recommended to have a light jacket or jumper for evening walks when the sun disappears behind the horizon.

Precipitation in Altenrhein falls quite regularly throughout the year, so there is no pronounced dry season here. Thanks to the temperate climate of Switzerland, rain and snowfall are distributed relatively evenly, although their nature changes depending on the time of year. In winter, especially in December and January, when the average temperature hovers around zero or drops lower, precipitation often falls as snow. December, incidentally, is one of the gloomiest months: statistics record about 18 days with precipitation.

The spring-summer period brings warming and a change in the nature of precipitation to rain. May stands out as the month with the highest frequency of rainy days — their number can reach 19. In summer, despite comfortable temperatures of around 18–22°C, rain is also not uncommon. August sees the highest volume of precipitation compared to other months, although the rains themselves can be short-lived and refreshing.

The least rainy periods, judging by the volume of precipitation, can be called February, March, April, and November. In these months, the intensity of precipitation decreases, and the number of "damp" days varies from 12 to 15. Nevertheless, when heading to Altenrhein, travellers should always have an umbrella or waterproof jacket with them, as the weather can be changeable in any season.

When packing for Altenrhein, it is worth remembering that the weather here is temperate but quite changeable, so the best strategy when choosing clothes is the principle of layering. Even in the warmest summer months, when the temperature rises to a comfortable 20-23°C, evenings can be cool, especially by the water. Therefore, regardless of the season, be sure to put a light jumper, cardigan, or fleece jacket in your suitcase, which can be easily removed or put on if necessary.

Pay special attention to protection from precipitation and wind. According to statistics, rain here is a frequent occurrence year-round (on average from 12 to 19 rainy days per month). A high-quality waterproof jacket with a hood or a reliable raincoat will be much more practical than a standard umbrella, especially if the wind picks up from Lake Constance. Also, do not forget comfortable, preferably waterproof flat-soled shoes, ideal for long walks around the city and the surrounding area.

For a winter trip, when temperatures stay around zero or slightly above, you will need a warm jacket, hat, and gloves. In the off-season, the weather can quickly change from sunny to overcast, so sunglasses and sunscreen should always be taken with you: the sun in the mountains and near the water can be active even on cool days. Such a well-thought-out wardrobe will allow you to feel confident and comfortable, enjoying the beauty of Switzerland in any weather.
