*** 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
Gammelstadsviken, a sheltered bay by Luleå in Norrbotten County, shows clear seasonal variation in water temperature. In summer, surface temperatures typically rise to about 15–20 °C (59–68 °F), occasionally reaching low twenties (68–72 °F) during warm spells in July and August. Late spring brings cool waters around 0–8 °C (32–46 °F) as ice recedes, while early autumn sees a steady decline to roughly 5–12 °C (41–54 °F). In winter the bay is often ice-covered and the water beneath the ice hovers close to freezing, generally around 0–4 °C (32–39 °F), making regular swimming impractical for most people.
Swimming is permitted and commonly practiced in summer at beaches, piers and public bathing areas around Gammelstadsviken, provided local safety and water-quality conditions are met. Because of the bay’s northern location and brackish character, swimmers should expect relatively cool water even in midsummer and check for designated entry points and lifeguard presence where available. Winter swimming or ice-bathing is undertaken by some enthusiasts but requires prepared ice holes, safety measures and experience; otherwise the ice cover prevents normal swimming and poses significant hazards.
