⚠️ 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.

Location & Local Information
Maardu Lake (Maardu järv) typically follows the seasonal temperature patterns of small Estonian lakes. In winter the surface usually approaches freezing, around 0–2 °C (32–36 °F) and can be ice-covered for extended periods. Spring sees a gradual rise, roughly 4–10 °C (39–50 °F) as the water mixes and warms. In summer the lake often reaches its highest temperatures, commonly between 18–24 °C (64–75 °F) and occasionally touching 25 °C (77 °F) on warm spells, making it comfortably swimmable for many people. During autumn the water cools again to roughly 8–15 °C (46–59 °F) as daylight shortens and air temperatures drop.
Swimming in Maardu Lake is generally permitted, but suitability depends on current water quality and safety conditions. The lake is relatively shallow and can warm quickly, which may encourage algal growth; authorities monitor bathing water and can issue advisories or temporary closures if pollution or cyanobacterial blooms are detected. Facilities and designated bathing spots are limited, so access and safety features vary by location. Visitors should check local notices before swimming, avoid areas with visible scum or foul odors, and take usual lake-safety precautions such as supervising children and being mindful of changing weather and cold shock outside peak summer temperatures.
