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
Cut Foot Sioux Lake, located in north-central Minnesota, typically follows the seasonal temperature patterns of many forested lakes in the region. In spring (April–June) surface waters are cool, often ranging from about 40–60°F (4–15°C) as snowmelt and spring rains flush cold water into the lake. Mid-summer (July–August) is when the lake is warmest; surface temperatures commonly reach roughly 65–75°F (18–24°C) in sheltered, shallow bays, while deeper water stays cooler. Early fall (September–October) sees a steady decline to about 55–70°F (13–21°C), and by winter the lake is ice-covered with surface ice at or below 32°F (0°C) while liquid water below the ice typically sits near 39°F (4°C).
Swimming at Cut Foot Sioux Lake is generally possible and commonly practiced in warmer months, but conditions influence whether it is advisable. There are often no staffed lifeguards or developed swimming facilities, so visitors rely on natural shorelines; cold water even in summer, sudden depth changes, underwater hazards, and occasional cyanobacterial (blue-green algae) blooms can create safety or health concerns. Local advisories, posted signs, or land manager guidance should be checked before entering the water, and basic precautions—swimming with others, using flotation, and avoiding cold-water immersion—are recommended.
