*** 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
Grapevine Lake, a reservoir north of Dallas–Fort Worth, experiences pronounced seasonal swings in surface temperature. In summer months surface readings commonly range from about 80–90 °F (27–32 °C) on warm days, while spring and fall typically see 55–75 °F (13–24 °C) as the water transitions with ambient air temperatures. Winter surface values can drop into the 40–55 °F (4–13 °C) range, especially after cold fronts. Deeper water remains colder year-round and the lake can stratify, so surface conditions are the most relevant for swimmers and recreational users.
Swimming is generally permitted in and around Grapevine Lake because it is managed for multiple recreational uses, including boating, fishing and shoreline activities. Many parks and boat ramps allow people to enter the water, but there are usually no lifeguards and some areas are better suited for wading than open-water swimming. Water quality advisories, algal blooms, boat traffic and seasonal temperature shifts can affect safety; for example, cold winter water increases hypothermia risk and late-summer algal events can prompt temporary closures. Visitors should choose designated recreational areas, check current advisories, and take standard safety precautions when swimming.
