Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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.

The river Renaelva in Innlandet County, Norway typically runs cold for most of the year, with surface temperatures that reflect seasonal variation, weather and local flow conditions. In winter the water is near freezing, commonly around 0–4 °C (32–39 °F). During spring thaw and early summer temperatures usually rise to roughly 2–8 °C (36–46 °F) as snowmelt feeds the river. Peak summer surface temperatures in sheltered, shallow stretches can reach about 10–18 °C (50–64 °F) on warm days, while deeper or faster-flowing parts remain noticeably cooler. In autumn the river cools again, often settling between 5–12 °C (41–54 °F) as air temperatures fall and rainfall increases. Local factors such as depth, shading, recent precipitation and any upstream regulation influence these ranges.
Swimming in Renaelva is generally permitted in principle, but practical safety and conservation considerations shape where and when people choose to enter the water. The cold temperatures, even in summer, can cause cold-water shock and fatigue, and some stretches have strong currents, uneven bottoms or boat and fishing activity; these conditions mean supervised or cautious swimming is advisable. Certain areas may be managed for angling or habitat protection, so checking local signage and seasonal restrictions is recommended before swimming. Overall, recreational swimming is possible in summer in calmer sections, provided swimmers take appropriate safety precautions.
