Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. 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.

Pirita jõgi, a modest river running into Tallinn Bay, shows marked seasonal variation in water temperature. In spring (March–May) thaw and snowmelt typically keep the river cool, roughly 2–8 °C (36–46 °F). Summer temperatures (June–August) are milder in lower stretches and sheltered bends, commonly ranging from about 14–22 °C (57–72 °F), though shallow or slow-moving spots can warm a few degrees higher on hot days. Autumn (September–November) brings a steady decline to around 6–12 °C (43–54 °F) as air temperatures fall, and in winter (December–February) the river is often at or near freezing—around 0–2 °C (32–36 °F)—with ice cover possible in cold years.
Swimming in the Pirita river is possible in many locations, especially in summer when temperatures are most comfortable, but it is not uniformly managed as an official large bathing area. Local conditions — water quality after heavy rain, currents, submerged obstacles and vegetation, and the presence or absence of lifeguards — affect safety, so swimmers should choose well-known spots and exercise caution. Some stretches closer to Tallinn’s recreational areas are used for informal bathing and water sports, while upstream or protected sections may be less suitable or restricted to protect nature.
