*** 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
Robinson Lake in Minnesota follows the familiar seasonal temperature pattern of small northern lakes. In spring the surface water typically ranges from about 40–60°F (4–16°C) as runoff and cooling weather keep temperatures low. By mid- to late summer surface temperatures commonly climb into the high 60s to upper 70s °F (20–26°C), with shallow bays warming fastest and deeper basins remaining several degrees cooler. In early fall temperatures usually fall back into the 50s–60s °F (10–18°C) as air temperatures cool. During winter the lake usually freezes; under-ice water temperatures stabilize around the mid-30s to upper 30s °F (1–4°C) while the ice surface is near 32°F (0°C).
Swimming is generally possible and frequently practiced in Minnesota lakes like Robinson Lake during the warm months when surface temperatures are comfortable, and public access or shore frontage permits recreational use. Whether swimming is officially allowed depends on local rules, ownership, posted signs and current water-quality advisories; seasonal algae blooms, low water clarity, or transient contamination can lead to advisories or temporary closures. Ice cover in winter makes casual swimming unsafe except for organized, well-supplied ice-swimming events with safety crews. As always, checking local postings and exercising standard water-safety precautions is recommended before entering the water.
