Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. 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
Lake Carmi’s water temperatures follow a typical New England pattern. In spring, as ice melts and air temperatures rise, surface readings commonly range from about 40–60°F (4–16°C). By early summer the lake warms into the 60s°F (around 16–21°C) and in July–August surface temperatures frequently reach the 70s°F (21–27°C), occasionally climbing into the low 80s°F (27–28°C) on the warmest days. Come fall the water cools back into the 50s–60s°F (10–16°C) and by winter the surface approaches freezing, about 32°F (0°C), with ice cover preventing normal swimming. Because Lake Carmi is relatively shallow in many areas it tends to warm more quickly in summer than deeper lakes, though deeper pockets remain noticeably cooler.
Swimming is allowed at Lake Carmi, especially at the state park’s designated beach during the warmer months when temperatures are comfortable for recreational use. Access and safety are controlled by park rules and posted advisories; water quality is monitored and officials may restrict swimming if conditions such as algal blooms or poor water quality are present. In winter, ice and near‑freezing temperatures make swimming unsafe, so recreational swimming is effectively limited to the late spring through early fall window when surface temperatures are suitable.
