*** 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
Ömmern in Västra Götaland County typically follows the seasonal temperature patterns of small Swedish lakes. In spring the water is cold, often around 2–10 °C (36–50 °F) as snowmelt and cool air keep temperatures down. By early summer in June the surface commonly rises to about 10–18 °C (50–64 °F). The warmest period is usually July and August, when surface temperatures can reach roughly 18–22 °C (64–72 °F) on sunny years. In autumn the lake cools again to roughly 8–14 °C (46–57 °F) and in winter it often drops below 4 °C (39 °F), with ice cover possible depending on the winter’s severity.
Swimming in Ömmern is generally possible and practiced during the warmer months because public access to shores is allowed under Swedish access rights and the lake reaches comfortable temperatures in midsummer. Local conditions vary, though, so swimmers should heed any municipal bathing advisories, watch for sudden weather changes, and be cautious of cold-water shock early and late in the season. In winter swimming is only for experienced ice bathers with appropriate safety measures, as thin ice and near-freezing water present significant risks.
