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
Stillhouse Hollow Lake, a reservoir near Belton, Texas, experiences a wide seasonal swing in surface water temperatures. In winter months the lake commonly cools to the 40s–50s °F (about 5–13 °C). Spring sees a steady rise, often moving into the mid‑50s to low‑70s °F (13–22 °C) as air temperatures warm and runoff increases. During summer the lake typically reaches its warmest, with surface temperatures frequently in the mid‑70s to upper‑80s °F (24–31 °C) and occasionally touching the low 90s °F (32–33 °C) on heatwave days. Temperatures fall again in autumn, commonly ranging from the low‑60s to mid‑70s °F (16–24 °C) as the season cools.
Swimming at Stillhouse Hollow is permitted but generally confined to areas designated for recreation and managed by park authorities. These areas exist because the lake is a working reservoir with boating, variable water clarity, submerged structure and seasonal vegetation that can create hazards outside marked zones. Lifeguards are infrequently provided, so swimmers should exercise caution, heed posted signage and any water‑quality advisories, and be mindful of boat traffic and sudden depth changes. In colder months the low water temperatures can increase risk of hypothermia, so many people limit swimming primarily to the warmer spring and summer periods.
