You may want to think twice before going for a dip. Eight beaches across the state, including two in Galveston, reported unsafe levels of fecal bacteria more than 25% of days they were tested.

Like all natural bodies of saltwater, Galveston’s beaches do contain naturally occurring bacteria, including Enterococcus and Vibrio vulnificus. Enterococcus levels are monitored by "Texas Beach Watch," and a spike often occurs after heavy rainfall washes animal waste and runoff into the Gulf. If levels exceed safe standards, an advisory is issued (usually lasting 48 hours), but the beach is rarely closed. Vibrio vulnificus, often misleadingly called "flesh-eating bacteria," is also naturally present and thrives in warm, brackish water. While the risk to healthy individuals is extremely low (less than 0.00035% of visitors are affected), it can be dangerous for those with liver disease, diabetes, or compromised immune systems who enter the water with open cuts or sores. In 2026, the best practice is to check TexasBeachWatch.com before you go, avoid the water if you have unhealed wounds, and always rinse off with fresh water after swimming.
