Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. 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
Andrusia Lake in Minnesota follows the seasonal temperature patterns typical of small northern lakes. Surface temperatures in spring and early summer generally range from about 40–60°F (4–16°C) as ice melts and the water warms; by midsummer surface readings often reach roughly 68–78°F (20–26°C) on warm days, with shallow bays sometimes climbing a few degrees higher. In early fall the surface cools back toward 50–68°F (10–20°C) as air temperatures drop, and under ice in winter the water hovers near freezing, roughly 32–39°F (0–4°C). Like many lakes, Andrusia can stratify in warm months, producing warmer surface layers and much cooler deep water, so temperatures can change quickly with depth and weather.
Swimming opportunities are generally available during the ice-free season where shore access exists; recreational swimming is common because summer surface temperatures often reach comfortable ranges for bathing. Whether swimming is officially allowed depends on local access points, signage, and any temporary advisories, so visitors should observe posted rules and recent water-quality notices. Swimmers should also be mindful of variable conditions such as sudden drop-offs, cold deeper water, and occasional blue‑green algal blooms, which can prompt temporary closures for safety.
