*** 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
Hammarsjön in Skåne County is a modest inland lake whose water temperatures follow the typical seasonal pattern of southern Sweden. In winter the surface often falls to around 0–4 °C (32–39 °F) and can freeze over in cold years. Spring temperatures rise to roughly 4–12 °C (39–54 °F) as the ice melts and the sun warms the shallow margins. Summer brings the warmest conditions, commonly 16–22 °C (61–72 °F) and occasionally higher during heat spells, making swimming most comfortable then. In autumn the lake cools again to about 8–14 °C (46–57 °F) as nights lengthen and sunlight decreases.
Swimming at Hammarsjön is generally possible and often practised by locals, because Swedish public access rights (allemansrätten) allow entering and bathing in many natural waters. That said, specific access or bathing may be limited by local regulations, nature protection rules, or temporary advisories for water quality, so it is sensible to check posted signs or municipal information before planning a swim. There are typically no lifeguards, and conditions such as sudden depth changes, vegetation or cold-water shock should be considered when deciding to enter the water.
