*** 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 Aiviekste is a Latvian river whose water temperature changes noticeably through the year. In spring the flow is cold, typically around 2–10 °C (36–50 °F) as snowmelt and rains keep the river chilly. During summer months the shallow stretches can warm to roughly 16–24 °C (61–75 °F), although cooler temperatures persist in deeper or faster sections. In autumn temperatures generally fall back to about 6–14 °C (43–57 °F) before winter sets in; in winter the river is often near freezing, around 0 °C (32 °F), and many reaches become ice-covered.
Swimming in the Aiviekste is generally possible in summer and at informal local spots, but it is not universally supervised or regulated along the whole course. Whether it is safe depends on local conditions: water quality can vary after heavy rains or agricultural runoff, currents and submerged hazards exist, and there are locations with stronger flow near weirs, bridges or sluices. For safety, people should choose known bathing spots, heed municipal signs, avoid areas with boat traffic or fast currents, and be mindful of cold shock outside the warmest weeks. Checking recent local water-quality information and following posted guidance is recommended.
