This page provides information on the current water temperature in Grenada Lake, trends, monthly ranges and the forecast for the coming days.
Current Water Temperature
Water Temperature in Grenada Lake today is 29.8°C.
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
Grenada Lake, a reservoir in northern Mississippi, experiences noticeable seasonal variation in surface water temperature. In summer months surface readings commonly range from about 75–85°F (24–29°C), which most swimmers find comfortable. Spring temperatures typically climb from roughly 55–75°F (13–24°C) as warming progresses, while autumn usually cools through a similar band around 60–75°F (16–24°C). Winter conditions bring the coldest surface waters, often in the neighborhood of 40–55°F (4–13°C); although the lake rarely freezes solid, these lower temperatures can feel harsh and increase the risk associated with prolonged immersion.
Swimming at Grenada Lake is generally allowed in developed recreation areas because the reservoir is managed for multiple public uses, including boating and bathing. However, designated beaches typically do not have lifeguards, so swimming is at one’s own risk, and visitors should heed posted advisories. Boat traffic, underwater drop-offs, variable currents near inlets or the dam, and occasional water-quality advisories — such as algal blooms after heavy runoff — make choosing appropriate locations and paying attention to local notices important. In colder months, the low water temperatures make swimming unsafe for prolonged exposure, so seasonal conditions should guide any decision to enter the water.
