The wettest time in terms of frequency is late spring and early summer: May and June lead the statistics with 18 to 19 rainy days per month.

In winter, especially in December and January, the nature of precipitation changes as temperatures drop. Since the thermometer can fall below freezing during this time (to -1.6°C), rain often turns to snow. The winter months also feature a high frequency of precipitation—up to 18 days in December—creating a true Swiss winter atmosphere, although the intensity remains moderate.

Relatively "drier" months include February and September, when the number of days with precipitation drops to 12–13. In summer, during July and August, rain occurs regularly (about 16 days) but is often refreshing. Overall, it is recommended to always have an umbrella or raincoat handy when visiting Biel/Bienne, as wet weather is common here but doesn't hinder sightseeing.

The weather in Biel/Bienne can be changeable due to its proximity to the lake and the Jura Mountains, so layering is the key rule when packing. Even in summer, when daytime temperatures rise to a comfortable 23°C, evenings can be cool and windy. Therefore, in addition to T-shirts and light trousers, be sure to bring a quality windbreaker, fleece, or sweater. In winter, when temperatures hover around freezing, you won't want to be without a warm down jacket, hat, scarf, and gloves.

Pay special attention to waterproof gear: statistics show that rain is a frequent occurrence in any season (averaging 12 to 19 rainy days per month). A compact, sturdy umbrella and a light raincoat will be your best friends on this trip. If you plan on long walks, choose outerwear made of membrane fabrics that protect against both wind and sudden rain.

To explore the historic streets and picturesque waterfront of Switzerland, you'll need the most comfortable shoes possible. Opt for broken-in sneakers or flat-soled boots with a water-repellent coating. It's best to leave heels for special occasions, as the cobblestones in the historic center are not shoe-friendly. Don't forget sunglasses and sunscreen, especially if you plan on boat trips on the lake, where the sun can be very intense.
