The Gulf of Mexico is responsible for Texas beaches being warm all year. There are exceptions, however, depending on when you visit the beach, some beaches might experience lower temperatures during winter due to strong winds from the gulf. Texas beaches have a variety of water temperatures, depending on where they are located and what time it is. The water temperature is generally warmer during the summer months with temperatures ranging from the low to mid-80s to the high-80s. However, water temperatures can reach the high 80s and low 90s in certain areas, such as South Padre Island during peak season. Again, the sand temperature will vary depending on when you are there and what beach you're at. In Texas, the sand is often too hot to walk on in the summer. However, the sand temperature in winter can be cooler and more moderate.
