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
Laguna Atascosa is a shallow coastal lagoon in southern Texas within the Laguna Atascosa National Wildlife Refuge near Brownsville. Because the water is shallow and connected to coastal influences, temperatures vary with the seasons. In winter (December–February) surface water typically runs about 55–65°F (13–18°C). Spring (March–May) sees a rise into the mid 60s to around 80°F (18–27°C). Summer (June–August) is the warmest period, with waters commonly between 80–95°F (27–35°C) on hot days. In fall (September–November) temperatures generally cool back to roughly 70–85°F (21–29°C). These are approximate ranges and local weather, tides and freshwater inflow can shift values from year to year.
Swimming and casual bathing are generally discouraged in Laguna Atascosa because much of the area is managed as a protected wildlife refuge rather than a designated recreational beach. Restrictions and advisories exist to protect sensitive habitats and nesting wildlife, and the lagoon’s shallow, muddy margins can present safety and water-quality issues such as submerged hazards, bacteria and occasional alligators. Visitors interested in water recreation should consult refuge rules and use designated public access sites elsewhere that are maintained and staffed for safe swimming.
