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
Greenleaf Lake in Oklahoma typically follows the same seasonal pattern as many small inland reservoirs in the region, with surface water temperatures that rise and fall with the air. In winter the lake can cool to roughly 35–50°F (2–10°C). Spring brings a steady warming to about 50–70°F (10–21°C) as runoff and longer days heat the shallows. Peak summer surface temperatures commonly reach roughly 75–85°F (24–29°C), and sometimes higher in heat waves, while fall usually drops back into a comfortable 55–70°F (13–21°C) range as cooling resumes.
Swimming at Greenleaf Lake is typically permitted in designated areas when conditions are safe, but it is dependent on water quality, posted regulations and safety considerations. Local authorities or the managing agency may close swimming zones during harmful algal blooms, high bacterial counts, low visibility, strong winds, or hazardous underwater conditions. Lifeguards are not always provided, so swimmers should be cautious about depth changes, submerged hazards and changing temperatures that can affect stamina. Visitors are advised to follow on-site signage and recent water-quality notices to determine whether swimming is advisable on any given day.
