*** 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 Waco, a reservoir on the Bosque River near Waco, Texas, experiences typical Central Texas seasonal water temperatures. During winter (December–February) surface temperatures commonly sit around 50–60°F (10–16°C). In spring (March–May) the water warms to roughly 60–75°F (16–24°C) as the days lengthen and runoff changes. Peak summer surface readings (June–August) often range from about 75–90°F (24–32°C), with shallow areas and heat waves pushing temperatures toward the upper end. In fall (September–November) the lake generally cools back to the mid‑60s to low‑80s°F (around 18–27°C) as air temperatures moderate.
Swimming at Lake Waco is possible in managed recreation areas, but it is subject to local rules because the reservoir also serves as a municipal water supply. The city and park authorities monitor water quality and may restrict access or issue advisories when conditions such as high bacteria counts or blue‑green algae (cyanobacteria) blooms threaten health. Visitors intending to swim should use designated swim zones where available, heed posted warnings, and take usual water‑safety precautions, since conditions and permitted activities can change with water quality, weather, and municipal policy.
