*** 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 Bastrop, a reservoir in central Texas, typically experiences a wide seasonal swing in surface water temperatures. In winter the lake often cools to roughly 45–55°F (7–13°C). Spring temperatures climb into the mid-50s to low 70s°F (13–22°C) as air temperatures warm. In summer the surface commonly reaches the mid-70s to upper 80s°F (24–31°C), and during heat spells can approach the low 90s°F (32–34°C). Fall sees a gradual cooling back into the 60s–70s°F range (16–24°C). Deeper water remains cooler year-round, so experienced boaters and divers can encounter noticeably lower temperatures below the surface.
Swimming is generally permitted at Lake Bastrop and the lake is used for recreational activities including shore and boat-based swimming, but there are few if any lifeguarded public beaches and some shoreline is privately owned or restricted. Because it is a managed reservoir rather than a designated municipal swim beach, swimmers should heed posted advisories, watch for algae blooms or water-quality notices, and be aware of submerged hazards and sudden drop-offs. Comfort for casual swimmers is usually best when surface temperatures are above about 70°F (21°C), although individual tolerance varies.
