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
The water temperature in the Lake of Pool 4 Sloughs at Pepin varies considerably through the year. During winter the sloughs hover around freezing, roughly 32–36°F (0–2°C) where ice forms and open water is rare. In spring, as runoff and warming progress, temperatures typically rise into the 40s–60s°F (4–16°C), still quite brisk for unprotected swimming. Summer brings the warmest conditions, with surface temperatures commonly between about 70–80°F (21–27°C) on average and occasionally reaching the low 80s°F (27–29°C) on hot, calm days. By autumn the water cools back into the 50s–60s°F (10–16°C) as air temperatures decline and stratification breaks down.
Swimming in the Pool 4 sloughs is physically possible in summer months, but it is not uniformly managed as a developed beach and conditions dictate whether it is advisable. Many areas are shallow, vegetated and can have murky water, submerged hazards, boat traffic and occasional algal blooms or bacterial advisories that affect safety. Access may also be restricted by private shoreline or by wetland protection. In short, the public may swim where access and local rules permit, but swimmers should check local signage and water-quality guidance, choose sheltered spots, and be mindful of cold shock outside peak summer warmth.
