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 Walter E. Long, east of Austin, experiences typical central Texas seasonal water temperatures. In winter the surface can drop into the 40s–50s °F (about 4–13 °C). Spring warms through the 50s and 60s °F (13–20 °C) into the 70s °F (around 21–24 °C) by late spring. Summer surface temperatures commonly reach the mid- to upper 70s up into the 80s and occasionally low 90s °F (roughly 24–33 °C). In autumn the lake generally cools back through the 60s and 70s °F (16–27 °C). These values vary with weather, depth, and seasonal inflows, so actual readings at the surface can shift from year to year.
Swimming at Walter E. Long is not offered as a formal, lifeguarded beach experience; the park and lake are more frequently used for boating, fishing, and wildlife viewing. As a result, any swimming is typically at visitors’ own risk, and local rules or posted signs may restrict access in particular areas. Concerns that affect swimming suitability include variable water quality, occasional algal conditions, underwater vegetation and debris, and the lack of designated safety supervision, so people should heed signage and local guidance before entering the water.
