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

Freeport sits on the upper Texas Gulf Coast where Matagorda Bay meets the Gulf of Mexico, giving it a mix of open-ocean and protected estuarine waters. Water temperatures vary seasonally: in winter months typical nearshore readings are about 13–18 °C, spring usually warms to roughly 16–23 °C, summer brings the warmest conditions around 25–30 °C, and autumn commonly sits between 20–25 °C. These ranges reflect both bay and gulf influences, with the shallow bay often running a few degrees warmer than the open Gulf on calm days. Short-term weather swings, cold fronts or prolonged heat, can push temperatures lower or higher than these averages at times.
