Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. 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.

Location & Local Information
Lake Ķīšezers in the Riga region is relatively shallow, which influences its seasonal water temperatures. In spring the surface usually warms from around 3–10 °C (37–50 °F) as ice melts and air temperatures rise. In summer the lake commonly reaches comfortable swimming levels, often 18–24 °C (64–75 °F) and during warm spells surface temperatures can climb to 25–27 °C (77–81 °F). In autumn the water cools again to roughly 6–12 °C (43–54 °F) as the air turns colder, and in winter the lake freezes in typical years; water immediately beneath the ice is close to 0 °C (32 °F), with only slight variations above freezing.
Swimming in Ķīšezers is generally permitted and is a common recreational activity at public beaches and shorelines, largely because the shallow nature of the lake allows it to warm in summer. However, local authorities may advise against entering the water if monitoring shows poor water quality or cyanobacterial (algal) blooms, and ice swimming should only be attempted where ice thickness and safety measures are verified by responsible bodies. As always, swimmers should heed posted warnings, avoid areas with visible pollution or scum, and consider seasonal temperature effects on comfort and safety.
