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
Lake Mullutu-Suurlaht (Estonian: Mullutu-Suurlaht) is a shallow coastal lagoon on Saaremaa whose depth and sheltered character strongly influence water temperatures. In spring the surface typically warms from about 2–12 °C (36–54 °F) as ice melts and sunlight increases. By early summer temperatures often reach 15–18 °C (59–64 °F), and in the warmest weeks of July and August the lake commonly sits around 18–22 °C (64–72 °F), with sheltered bays sometimes climbing to 24–26 °C (75–79 °F) on calm, sunny days. In autumn the water cools back through roughly 8–14 °C (46–57 °F) before freezing. Winter conditions bring surface temperatures close to 0–4 °C (32–39 °F) and the lake frequently forms ice cover.
Swimming in Mullutu-Suurlaht is generally allowed and practiced by locals because it is a public natural waterbody, and the shallow basins warm quickly for summer bathing. However, the same shallowness and abundant reeds can lead to higher turbidity, vegetation and occasional algal blooms, so water quality varies by area and season; swimmers should choose clear spots and heed any local advisories. In winter, ice swimming is possible where safe, but caution is essential because ice thickness can be uneven.
