❌ As of today, the minimum water temperature ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold.

*** 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
Köping, in Västmanland County, sits close to inland waters such as local lakes and the Kolbäcksån river, and water temperatures vary with season, depth and exposure. In summer, open shallow bays and sheltered lake areas typically warm to about 18–22 °C (64–72 °F), and during warm spells can reach 24–26 °C (75–79 °F). Rivers and deeper lake zones are usually a few degrees cooler, often 14–18 °C (57–64 °F) in midsummer. Spring brings a rapid warming from near 2–10 °C (36–50 °F) as ice melts, while autumn sees cooling from about 10–15 °C (50–59 °F) in early September down toward single digits. In winter the water is close to freezing, typically around 0–2 °C (32–36 °F) where unfrozen and often ice-covered for periods.
Swimming in Köping’s lakes and designated bathing areas is generally permitted; Sweden’s tradition of public access and local bathing sites make summer swimming common. Authorities commonly monitor water quality during the bathing season and post warnings if bacterial levels rise after heavy rain or pollution events. Caution is advised in rivers because of currents and colder temperatures, and ice swimming requires proper safety measures. As always, local signage and municipal guidance should be followed for safe bathing.
