Stay Safe in the Water!
Avoid rock jetties and piers at all times. Don’t dive into unknown depths. Be aware of strong surf. And, most importantly, know the meanings of the colored flags posted at each beach denoting current water conditions and swim near a lifeguard:
| Flag Color | Condition |
|---|---|
| Conditions calm | |
| Use caution | |
| Poor air / water quality | |
| Strong winds & currents | |
| Dangerous marine life |
Why Does the Gulf Change Colors?
The water off the coast of Galveston is turbid, meaning it lacks clarity. This turbidity is a result of suspended solids in the water like sediment, plankton and microorganisms.
The Gulf and Bay floor around Galveston is shallow and covered in very fine silt. This means that wind and waves can easily disturb and suspend the silt in the water. On a calm day, the water around Galveston is actually a lovely shade of blue.

What Is That Weed?
Every year, there is a potential for large masses of Sargassum (seaweed) to wash up along Galveston’s beaches during the spring and early summer months. The name seaweed incorrectly implies that these brown algae have little value. In fact, this floating habitat provides food, refuge, and breeding grounds for an array of animals such as fish, sea turtles, marine birds, crabs, shrimp, and more. Sargassum also serves as a primary nursery area for a variety of commercially important fish such as mahi mahi, jacks, and amberjacks. And once arriving onshore, it becomes an invaluable food source for many coastal birds.
If you see seaweed floating, grab a handful and quickly shake it to see some of the distinctive, well-camouflaged creatures that call it home.
