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

Snakeden Hollow’s lakes are former strip‑mine pits, so their water temperatures vary widely by season, depth, and local weather. Surface readings in spring commonly range from about 40–65°F (4–18°C) as waters warm after ice melt, while midsummer surface temperatures often reach roughly 65–80°F (18–27°C) in shallower basins. In contrast, deeper holes can remain cool even in summer, frequently holding water in the 40–50°F (4–10°C) range below the thermocline. During autumn the surface generally cools back toward 40–65°F (4–18°C), and in winter lakes may ice over with near‑freezing conditions around 32°F (0°C) where ice forms.

Swimming at Snakeden Hollow is not promoted because there are no developed public swimming beaches or lifeguarded facilities, and management emphasis is on fishing and wildlife habitat. The former‑mining topography produces steep drop‑offs, submerged rubble and brush, and cold deep water that can create dangerous conditions for casual swimmers, including risk of hypothermia and entrapment. For those considering water recreation, canoeing or fishing from boats is common, but direct contact with the water should be approached cautiously and only after confirming site‑specific rules and safety provisions.
