*** 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
Storfjärden (Swedish: Storfjärden) in Uppsala County typically follows the seasonal temperature patterns common to lakes in this part of Sweden. During summer months the surface water usually warms to roughly 18–24 °C (64–75 °F) in sheltered shallows, occasionally reaching the mid‑20s in heatwaves. Spring temperatures rise from about 2–10 °C (36–50 °F) as ice melts and the water stratifies, while autumn sees cooling to roughly 6–14 °C (43–57 °F). In winter the lake often approaches near‑freezing conditions, with water under ice commonly around 0–4 °C (32–39 °F) where the surface is frozen; open water in cold spells will be very cold and unsuitable for prolonged exposure.
Swimming at Storfjärden is generally possible and commonly practiced in summer because many shorelines are publicly accessible and there are no universal prohibitions, but local rules, water quality advisories and private properties can restrict access in specific spots. Bathing conditions vary with depth, vegetation, weather and the absence of lifeguards, so swimmers should choose entry points with clear access, be aware of sudden depths and check current local signage or municipal information about algae blooms or contaminants. Ice swimming is practiced by experienced individuals when the ice is thick and safety measures are in place, but it is hazardous without proper precautions.
