Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing 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
Jelgava (in Latvian – Jelgava) sits on the Lielupe River and near several small lakes and ponds that are used for recreation. Water temperatures in these inland waters vary by season: in summer surface temperatures commonly range from about 18–24 °C (64–75 °F), with warm spells occasionally bringing shallow areas up to 25–26 °C (77–79 °F). During spring temperatures typically rise from roughly 4–14 °C (39–57 °F) as ice melts and the water warms, while autumn values fall from about 8–18 °C (46–64 °F) as cooling sets in. In winter, temperatures often approach freezing, around 0–4 °C (32–39 °F), and some smaller water bodies can freeze over during cold periods.
Swimming is generally allowed in Jelgava’s designated bathing spots when local authorities monitor and confirm acceptable water quality and safety conditions. Municipal testing for bacteria and cyanobacteria, visible pollution, and weather-related hazards determines whether a site is suitable for bathing; lifeguards or posted signs may indicate safe periods. Swimmers should avoid unsupervised areas when currents, low temperatures, poor visibility or algal blooms are present. Winter ice swimming happens occasionally but should only be undertaken at supervised, approved locations with proper equipment and knowledge of ice safety.
