*** 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
Uddevalla, in Västra Götaland County, has a number of freshwater lakes and rivers inland from its coastal location. Seasonal surface temperatures in those water bodies follow a typical southern Swedish pattern: in spring (April–June) lake and slow‑flowing river surfaces commonly range from about 4–12 °C (39–54 °F) as ice melts and water cools from runoff, while in summer (June–August) sheltered lakes often warm to roughly 16–22 °C (61–72 °F) and shallow ponds can reach the upper part of that range. Rivers and fast‑flowing stretches tend to be a few degrees cooler year‑round and respond quickly to rainfall. In autumn (September–November) temperatures generally fall to around 8–14 °C (46–57 °F) before winter brings ice and near‑freezing water around 0 °C (32 °F) on lakes, with flowing rivers remaining just above freezing in many stretches.
Swimming in Uddevalla’s lakes and calmer river spots is commonly permitted and popular during the warmer months, both at maintained bathing areas and by people practising wild swimming, though access can be limited by private shoreline. Local authorities monitor water quality and may post advisories for blue‑green algae or pollution after heavy rains, so checks are recommended before entering the water. Safety considerations include colder river currents, variable visibility, and ice conditions in winter; open‑water winter swimming is practiced by some but requires caution and proper support.
