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
Round Rock, Texas, is located near several rivers and lakes that offer recreational opportunities, though the city itself is not known for extensive natural swimming areas. One of the primary water features in the area is Brushy Creek, which flows through the city and provides opportunities for activities such as fishing and kayaking. However, swimming in Brushy Creek is not a common practice due to the variability in water quality, especially after rainstorms. The water temperature in the creek typically ranges from 60°F to 75°F (16°C to 24°C), with the warmer temperatures reaching their peak during the summer months.
For those looking for more suitable places to swim, Round Rock is located close to several larger lakes. Lake Georgetown, just a short drive away, is a popular destination for outdoor activities, including swimming. The water temperature in Lake Georgetown can rise to 75°F to 85°F (24°C to 29°C) in the summer, making it a pleasant spot for swimming, boating, and fishing. The lake offers designated swimming areas, where the water is cleaner and more conducive to swimming compared to some of the nearby creeks. In addition to lakes and rivers, Round Rock also has several community pools, which are a safe and popular choice for residents seeking a swim during the hot Texas summers.
