*** 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
Strømmen (Norwegian: Strømmen) in Akershus County sits near rivers and small lakes typical for the Oslo region. Water temperature in local lakes varies by season: spring surface temperatures commonly range from about 4–12 °C (39–54 °F) as ice thaws, summer highs usually reach 16–22 °C (61–72 °F) with warmest conditions in July and August, autumn cooling brings 8–15 °C (46–59 °F), and winter temperatures hover around 0–4 °C (32–39 °F) where ice cover can form. Shallow, sheltered bays warm faster and may be a few degrees warmer than exposed areas, while deeper or flowing sections stay cooler. Weather and recent sunshine strongly influence short-term variations.
Swimming is generally permitted in lakes around Strømmen and is a common summer activity at designated bathing spots, since municipalities maintain some beaches and monitor water quality. There are no universal bans, but swimmers should heed local signs about water quality, blue-green algae, or safety warnings; lifeguards are not always present. Early and late season swimming carries cold-shock risks, and winter swimming is only advisable for experienced, well-prepared individuals using proper precautions.
