*** 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
Lakes in and around Valmiera typically follow the temperate Baltic seasonal cycle, so surface water temperatures vary notably over the year. In summer, common surface readings are about 18–24 °C (64–75 °F), with occasional warm spells pushing shallow bays to 25–26 °C (77–79 °F). During spring and early summer warming and in autumn cooling, temperatures commonly sit between 4–15 °C (39–59 °F), depending on air temperatures and sunshine. Deeper water layers remain cooler year-round. In winter, lake surfaces approach 0 °C (32 °F) and lakes often freeze, with ice thickness varying by season and weather.
Swimming is generally allowed in suitable places because summer temperatures reach comfortable bathing ranges and there are designated beaches and waterfronts that support recreational use. Local authorities monitor water quality at official bathing spots and post advice or restrictions when necessary, so swimming is encouraged only where signs indicate it is safe. Caution is advised near river outflows, in undeveloped shoreline areas, and during spring thaw or after heavy rains when currents and clarity can change. Ice swimming occurs as a cultural practice but requires proper safety measures and local guidance since frozen conditions can be hazardous.
