❌ 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.

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
Nömmen is a small lake in Jönköping County known locally as Nömmen. Water temperatures vary by season: in spring (March–May) the surface typically warms from about 2–12 °C (36–54 °F) as snowmelt and cool air still influence the water. In summer (June–August) the lake often reaches its warmest range, commonly 16–22 °C (61–72 °F) on average, with shallow bays sometimes getting a few degrees warmer on hot, calm days. During autumn (September–November) temperatures fall back to roughly 4–12 °C (39–54 °F) as nights cool and stratification breaks down. In winter (December–February) the surface frequently drops to around 0–4 °C (32–39 °F) and the lake can ice over in cold spells, making open-water swimming uncommon and potentially hazardous.
Swimming at Nömmen is generally allowed, reflecting Sweden’s right of public access (Allemansrätten) and the many informal bathing spots around regional lakes. Whether it’s advisable depends on conditions: water quality, local rules, private shoreline, weather and ice cover should be checked before entering. There are often no lifeguards, so swimmers should be cautious of low temperatures, sudden depth changes and boat traffic. For safe enjoyment, choose sheltered, shallow areas in summer and heed local signage or municipal information about water quality and access.
