Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. 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 Gauja River in Latvia typically shows clear seasonal variation in water temperature. In winter (December–February) surface temperatures are often around 0–3 °C (32–37 °F) and the river can freeze in places. Spring (March–May) brings a gradual rise, commonly 2–10 °C (36–50 °F) depending on meltwater and rain. Summer (June–August) is the warmest period, with typical surface temperatures of about 16–22 °C (61–72 °F) and occasional peaks near 24 °C (75 °F) in prolonged heat. Autumn (September–November) cools again to roughly 8–14 °C (46–57 °F). Local conditions such as depth, flow speed, shading and recent weather cause notable variation: shallow, slow-moving stretches warm faster while fast or shaded sections remain cooler.
Swimming in the Gauja is generally possible and frequently enjoyed in summer at designated bathing spots, but it is subject to local rules and natural hazards. Many towns and recreation areas authorize swimming and may provide supervised places, while other stretches—especially within protected park zones or near rapids, submerged rocks and strong currents—may be restricted or unsafe. Cold spring and autumn water significantly raise hypothermia risk, and winter swimming is only for experienced, well-prepared individuals using proper precautions. Visitors should follow signage, local guidance and common-sense safety practices before entering the river.
