*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Västerås (Swedish: Västerås) in Västmanland County sits on the shores of Lake Mälaren, where water temperatures vary noticeably through the year. In winter the lake is usually near freezing, roughly 0–4 °C (32–39 °F). Spring temperatures climb from about 2–12 °C (36–54 °F) as the ice melts and the water warms. In summer the water commonly ranges between 16–24 °C (61–75 °F), and during warm spells surface temperatures can approach or exceed the mid‑20s °C (mid‑70s °F). Autumn sees a steady cooling to roughly 6–15 °C (43–59 °F) before the onset of ice, with local and year‑to‑year variation depending on weather and wind.
Swimming in Västerås is generally permitted and popular, with several municipal beaches and designated bathing areas maintained for public use. The municipality monitors water quality and posts advisories when there are algal blooms or elevated bacteria levels after heavy rain; lifeguards are present at some beaches during the peak season. Winter swimming or ice bathing is practised by some, but it requires proper precautions because ice thickness, water temperature and safety conditions vary. Overall recreational swimming is allowed because of public access and managed bathing sites, though users should heed posted warnings and seasonal restrictions for health and safety.
