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
Lake Odessa’s water follows the seasonal pattern typical of small Iowa lakes. In winter the surface is typically at or just above freezing, around 32°F (0°C) and often ice-covered. Spring sees a steady rise from the 40s–50s°F (4–15°C) as runoff and warming air temperatures mix the water. By late spring into early summer surface temperatures commonly range from the mid-60s to low 70s°F (18–23°C), and in the warmest weeks of July and August the lake often warms to the low to upper 70s°F (22–27°C), sometimes spiking briefly into the 80s°F (27–31°C) during heat waves. Temperatures begin to decline in autumn back through the 50s–60s°F (10–16°C) before returning to near-freezing.
Swimming at Lake Odessa is generally allowed in designated recreational areas during the warmer months because the lake and its shoreline are managed for public use. However access is subject to local rules and conditions: beaches may be closed for safety, high bacterial counts, or harmful algal blooms, and ice cover makes swimming unsafe in winter. Visitors should use marked swim areas, heed posted advisories, and be aware that temperatures remain cool into late spring and decline again in fall, which can affect comfort and safety in the water.
