Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Norrköping (in Swedish - Norrköping) sits beside freshwater courses such as Motala Ström and a number of small inland lakes in Östergötland County. Surface temperatures in these rivers and lakes follow seasonal patterns: in spring they typically range from about 2–12 °C (36–54 °F) as ice melts and water flow remains cold; in summer shallow lakes can warm to roughly 18–25 °C (64–77 °F) while flowing rivers are usually cooler, around 15–20 °C (59–68 °F); early autumn often sees temperatures fall to 8–14 °C (46–57 °F) and by late autumn into winter many still waters and slower river stretches drop toward 0–4 °C (32–39 °F), with ice cover possible. Local variations occur depending on depth, shading, inflow from tributaries and recent weather, so one spot can be several degrees different from another on the same day.
Swimming in Norrköping’s lakes and rivers is generally permitted because Swedish public access rules allow bathing in most freshwater bodies, and the municipality maintains some designated bathing sites with water quality checks and occasional lifeguards during the summer months. Caution is advised: currents, low temperatures outside summer, underwater hazards and variable water quality can pose risks. Winter ice swimming is practiced by some locally but requires careful safety measures and knowledge of ice conditions, and municipal provision is limited outside the organized bathing season.
