*** 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 Arthur, located in southwestern Louisiana, tends to have relatively warm water compared with more northerly lakes because of its shallow depth and subtropical climate. Seasonal surface temperatures commonly range from about 50–65°F (10–18°C) in winter, warming to roughly 65–80°F (18–27°C) in spring. Summer temperatures often climb into the upper 70s to low 90s °F, roughly 26–33°C, especially during heat waves, while fall typically sees a gradual cooling back into the 70s °F (21–27°C). Shallow areas and sheltered bays warm fastest, so localized surface readings can be several degrees higher than open-water averages on calm, sunny days.
Recreational swimming in and around Lake Arthur is generally possible, but conditions vary and there are typically no lifeguards or formal public swimming beaches. Local authorities sometimes advise against swimming when algae blooms, high bacteria counts, or storm runoff have degraded water quality, and boat traffic, submerged vegetation, and occasional alligators can present hazards. For safety and health, swimmers should check current local advisories or water-quality reports before entering, avoid swimming near boat channels, and be mindful that shallow, warm waters increase the risk of nuisance algae and contaminants.
