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
Intermediate Lake, like many mid-Michigan inland lakes, undergoes pronounced seasonal temperature swings. In winter the surface typically approaches freezing, often around 32°F (0°C) with ice cover common; under-ice temperatures remain close to 32–39°F (0–4°C). Spring sees a gradual warming, generally from the mid-30s to mid-50s°F (about 2–13°C) as snowmelt and runoff cool the water. By summer the lake commonly reaches its warmest, often in the mid-60s to mid-70s°F (18–24°C) and on warm stretches sometimes approaching 80°F (27°C) at the shallowest, sun-exposed spots. Temperatures decline again in fall, typically falling into the 40s and 50s°F (7–15°C) as air temperatures drop and stratification breaks down.
Swimming in Intermediate Lake is allowed seasonally and is a common recreational activity where shoreline access or public beaches are present. Local rules, posted advisories, and private property rights can affect where swimming is permitted, and water-quality or algal-bloom notifications may temporarily restrict swimming. Practical considerations influence when people swim: water temperatures above roughly 70°F (21°C) feel comfortable for many swimmers, while colder springs and the near-freezing winter period make swimming impractical and potentially hazardous. As with any lake, swimmers should be mindful of sudden temperature changes below the surface, variable depths, and standard water-safety precautions.
