*** 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 Blackshear, a reservoir in south-central Georgia, experiences noticeable seasonal shifts in surface water temperature. During winter months the surface commonly cools to roughly 40–55°F (4–13°C). In spring temperatures rise into the mid‑50s to mid‑70s°F (13–24°C) as air temperatures warm and runoff changes. Peak summer surface temperatures frequently reach the mid‑70s to upper‑80s°F and can occasionally climb toward 90°F (24–32°C and up to ~32°C), making the warmest weeks most comfortable for bathing. In autumn the lake typically cools back into the 60s and low‑70s°F (16–23°C) before entering winter decline. These are general ranges; thermal conditions vary with weather, depth, and local inflow.
Swimming is permitted in many of the lake’s recreation areas and at facilities that manage beaches or boat‑launch zones, but it’s governed by local rules and posted signage. Authorities may restrict or advise against swimming because of boat traffic, submerged hazards, water temperature, or water‑quality concerns such as bacterial contamination or algal blooms, so swimmers should use designated beach areas, heed warnings, and avoid cold‑water immersion in winter unless wearing protective gear. Lifeguards are not always present, so exercising caution and checking current local advisories before entering the water is recommended.
