*** 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
Täby’s inland water bodies — small lakes and slow rivers in the municipality — follow the typical temperate Swedish pattern. In spring (March–May) surface temperatures usually climb from just above freezing to about 4–12 °C (39–54 °F). Early summer and June commonly see 10–18 °C (50–64 °F), while July–August often yield the warmest surface readings around 18–23 °C (64–73 °F), occasionally reaching 24–25 °C (75–77 °F) in hot summers. Autumn brings cooling to roughly 8–14 °C (46–57 °F) in September–October, and in winter many lakes approach 0 °C (32 °F) and may freeze over.
Swimming in Täby’s lakes and rivers is generally allowed and enjoyed at designated beaches and municipal bathing spots when water quality and conditions are safe. The calm, shallow nature of many freshwater sites makes them suitable for families and casual swimmers, though lifeguards are not always present. Local authorities monitor bacterial levels and warn against swimming after heavy rain or during blue‑green algae blooms; such advisories are the main reason access may be temporarily restricted. Ice swimming is practiced by some in winter where ice and safety measures are in place, but it requires special precautions and local guidance.
