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
O. H. Ivie Reservoir in central Texas experiences pronounced seasonal swings in surface water temperature. In spring the surface commonly warms from about 60–75°F (15–24°C) as days lengthen and inflows moderate. Peak summer surface temperatures frequently reach 75–95°F (24–35°C) on hot afternoons, while cooler nights and wind can reduce that somewhat. In autumn the surface tends to fall back into a 50–70°F (10–21°C) range as air temperatures cool. Winter surface readings often drop to roughly 40–55°F (4–13°C). Deeper water remains appreciably cooler than the surface, especially during summer stratification, and short-term factors such as recent rains, wind, and water releases can shift temperatures locally and rapidly.
Swimming in O. H. Ivie Reservoir is generally possible but not formally supervised; there are no widespread lifeguarded beaches and access points are primarily designed for boating and fishing. Because of heavy boat traffic in popular areas, submerged structure, variable water quality and occasional algae or debris, swimmers should exercise caution, wear personal flotation when appropriate, and avoid isolated or heavily used launch zones. Local rules or temporary advisories can restrict activities, so checking with managing authorities or signage before entering the water is advisable.
