*** 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 Washington in Mississippi typically follows the seasonal patterns of shallow southern lakes, with surface temperatures that rise and fall with air temperature and river influence. In winter (December–February) surface water commonly ranges from about 45–55°F (7–13°C). Spring (March–May) usually warms to roughly 55–70°F (13–21°C) as days lengthen and sunlight increases. Peak summer readings (June–August) often reach about 75–90°F (24–32°C) at the surface on hot, calm days, while autumn (September–November) generally cools back toward 60–75°F (16–24°C). Actual temperatures vary with depth, recent weather, and river flows, and small-scale factors like shading and groundwater seeps can produce local differences.
Swimming in Lake Washington is physically possible and commonly done in suitable spots, but conditions determine whether it is advisable. There are not many formal lifeguarded beaches on small oxbow lakes, and local regulations or posted advisories may restrict access at certain times for safety or water‑quality reasons. Hazards can include submerged trees and snags, boat traffic, variable currents, and occasional algal blooms or elevated bacteria after heavy rains, so swimmers should heed signage, check with local authorities about current water‑quality reports, and use caution when entering the water.
