*** 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
Vernon Lake in Louisiana typically follows the temperature patterns of shallow, inland southern lakes, with noticeable seasonal swings. In summer the surface often warms into the high 70s to high 80s °F (about 26–31 °C), especially on sunny, calm days. Spring and fall are transitional, with general ranges from roughly 60–75 °F (15–24 °C) as air temperatures moderate and inflows cool or heat the water. Winter surface temperatures commonly fall into the mid-40s to low 60s °F (about 7–16 °C), though deeper pockets may stay a few degrees warmer. Actual readings vary by depth, recent rainfall, wind, and the specific year, so these figures are approximate rather than constant.
Recreational swimming is often possible at lakes like Vernon Lake, but whether it is allowed or advisable depends on local rules, posted signage, and current conditions. Warm summer temperatures can make swimming comfortable, but hot-weather algal blooms and debris sometimes prompt advisories against entering the water. Conversely, water under roughly 60 °F (15 °C) can be uncomfortable and increase the risk of cold-related issues with extended exposure. Because many lakes lack lifeguards and may have submerged hazards or fluctuating water quality, visitors should verify local guidance and exercise caution before swimming.
