Surfside Beach — Water Temperature, Sea Conditions & Trends

Water Temperature: Daily Trends, Historical Records, and Forecast

✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating.

It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

Annual Water Temperature Trend

Surfside Beach, on the upper Texas Gulf Coast, offers a wide, sandy shoreline and relatively shallow nearshore waters that respond quickly to seasonal heating and cooling. Typical sea surface temperatures vary through the year: in winter (December–February) the water commonly ranges from about 11 °C to 17 °C, with occasional cold snaps pushing temperatures toward the lower end. During spring (March–May) the Gulf gradually warms to roughly 16 °C–23 °C. Summer months (June–August) bring the warmest conditions, with coastal waters generally between 25 °C and 31 °C, peaking in July and August. Autumn (September–November) sees a steady cooling from the high summer values to approximately 20 °C–26 °C. Local factors such as wind, tides, and short-term frontal passages can cause noticeable daily variation, so those numbers represent typical seasonal ranges rather than exact forecasts.
