*** 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
Linwood Lake in Minnesota follows the predictable seasonal pattern of northern lakes, with surface temperatures that vary widely through the year. After ice-out in spring, water typically runs cold, roughly 35–55°F (2–13°C) as the lake stratifies. By summer the surface commonly warms to about 68–78°F (20–26°C) on warm, sunny days, offering the most comfortable conditions for swimming. Early fall sees a gradual cooling to approximately 55–68°F (13–20°C), while late fall and winter bring temperatures back toward freezing; surface water under ice usually approaches 32–40°F (0–4°C), with deeper layers remaining somewhat warmer.
Swimming is generally permitted at Linwood Lake where shoreline access is available, and many visitors swim from public access points, private beaches, or docks. There are typically no statewide prohibitions on recreational swimming in natural lakes, but actual access and safety depend on local management, water quality advisories, and conditions such as submerged hazards, currents, or algae blooms. Because there are usually no lifeguards, swimmers should exercise caution, check current water-quality and access information from local authorities, and choose summer months for the warmest and safest swimming conditions.
