Water Temperature: Daily Trends, Historical Records, and Forecast

✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. 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

Surface water generally warms from near freezing in winter—around 32–40°F (0–4°C)—to spring turnover temperatures of roughly 40–60°F (4–16°C). In summer, shallow lakes commonly reach their warmest range, about 70–80°F (21–27°C) on warm afternoons, with occasional highs a few degrees above that on heat waves. By fall the surface cools back through roughly 50–65°F (10–18°C) as air temperatures drop. Actual temperatures at Tampier Lake will vary by depth, shading, inflow, and recent weather; deeper zones remain colder year-round.

Whether swimming is allowed at Tampier Lake depends on local management and water quality rather than temperature alone. Many community or county lakes permit swimming only at designated beaches when water-quality monitoring, lifeguards, or signage are in place. Authorities may prohibit or advise against swimming because of cold water and hypothermia risk (temperatures below ~60°F/15.5°C can be uncomfortable and present cold-shock concerns), bacterial contamination or harmful algal blooms, submerged hazards, or lack of safety services. For a definitive answer, check with the lake’s managing agency or posted signage before swimming.
