Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 65°F (18°C) to 68°F (20°C). This is already quite warm water, which is ideal for most people. Swimming becomes comfortable, and prolonged stays in the water do not cause discomfort. This temperature is perfect for family trips and for those who prefer warmer water. It is also comfortable for water sports such as surfing or swimming. 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
Black Lake in northern Michigan follows the seasonal pattern typical of inland glacial lakes. After ice-out in spring, surface temperatures usually range from roughly 40–60°F (4–16°C) as the water gradually warms through April and May. By summer, especially in July and August, surface readings commonly reach the mid-60s to upper-70s °F (about 18–26°C), with shallow bays and protected coves sometimes warming into the low 80s °F (around 27–28°C) on hot, calm days. In autumn the lake cools back into the 50s–40s °F (10–4°C) through September and October. Winter brings ice cover and water at or just above freezing, about 32°F (0°C) at the surface under solid ice with slightly warmer but near-freezing temperatures under the ice.
Swimming is generally allowed where public access, beaches or private properties provide entry, and many people swim during the warm summer months because surface temperatures can be comfortable. Local health or park authorities may post advisories or close swim areas if water-quality issues such as algal blooms or bacterial contamination arise, so checking current conditions is wise. Cold spring and fall waters pose hypothermia and cold-shock risks, and winter ice can be hazardous for swimming or thin-ice activities, so swimmers should use caution and follow posted guidance.
