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
Allgunnen (Swedish: Allgunnen, Kalmar) is a typical lake in Kalmar County where water temperatures follow the seasonal patterns of southeastern Sweden. In early spring the surface can be close to freezing, around 0–6 °C (32–43 °F), rising in late spring to roughly 6–12 °C (43–54 °F). Summer months usually bring the warmest values, commonly 15–22 °C (59–72 °F) and occasionally reaching about 24 °C (75 °F) during heat waves. In autumn the surface cools again to roughly 8–14 °C (46–57 °F), and in winter the lake may ice over or hover near 0 °C (32 °F). Local factors such as depth, inflow, and weather can shift these ranges from year to year.
Swimming in Allgunnen is generally allowed, reflecting Sweden’s tradition of public access and informal bathing at suitable shores. Many people swim there in summer when temperatures are comfortable, and some practice ice swimming in winter where conditions and safety measures permit. Access can be limited by private property, protected areas, temporary algae blooms or water-quality advisories, so it is sensible to check local signs and conditions before entering the water and to observe standard safety precautions for temperature and depth.
