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
Hedemora (Swedish: Hedemora) and its surrounding municipality in Dalarna have a typical inland Scandinavian climate that strongly influences lake and river temperatures. Shallow lakes and sheltered bays commonly reach surface temperatures of about 18–24 °C (64–75 °F) in peak summer (July–August), while deeper lakes warm only to about 12–18 °C (54–64 °F). Spring and early summer (May–June) see rapid warming from near 4–8 °C (39–46 °F) up to mid-teens, and in autumn (September–October) surface temperatures typically fall from around 10–15 °C (50–59 °F) down toward 4–8 °C (39–46 °F). Rivers in the area are usually cooler and more variable; summer temperatures commonly range from 8–15 °C (46–59 °F) in faster-flowing stretches, with colder pockets year-round. In winter most lakes and many rivers are close to freezing, often 0–2 °C (32–36 °F) under ice cover.
Swimming in lakes and slow-flowing rivers around Hedemora is generally allowed and common at designated beaches and privately maintained bathing spots, supported by Sweden’s public access rights (allemansrätten) and local bathing water monitoring during summer. Safety considerations—water temperature, sudden depth changes, undergrowth, currents in rivers and occasional local pollution sources—mean some places are unsuitable for casual swimming. Municipal advisories and posted signs should be followed for water quality and safety information.
