❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. It is important to note that these swimming tips and recommendations apply only in good weather.

*** 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
Strängnäs sits on the shores of Lake Mälaren in Södermanland, and water temperatures follow a clear seasonal pattern. In winter the surface is typically close to freezing, around 0–4 °C (32–39 °F), often with ice in the coldest months. Spring sees a gradual rise, roughly 2–12 °C (36–54 °F) as the ice melts and the water stratifies. Early summer brings milder conditions of about 12–18 °C (54–64 °F), while peak summer temperatures in July and August commonly reach 18–22 °C (64–72 °F) in sheltered bays during warm years. By autumn the surface cools again to about 10–15 °C (50–59 °F) as the water mixes and loses heat.
Swimming in and around Strängnäs is generally allowed; Swedish access rights and local bathing spots make the lake reachable for recreational use. Municipalities often monitor popular beaches for bathing water quality in summer, so swimmers should heed local advisories about bacterial levels or cyanobacteria blooms and avoid stagnant, shallow bays when warnings are posted. Cold‑water and ice swimming are practiced by some, but require appropriate safety measures such as companions, flotation aids or cut‑out ice facilities. Boat traffic and variable depths also call for caution even at warmer temperatures.
