Is there a small craft advisory for Matagorda Bay?

No advisories, warnings or watches are in effect for NWS zone GMZ330 as of the last update on this page. Advisories can be issued at any time; check the current bulletin before leaving the dock.

The nearest buoy read 85°F (29°C) at Tue 1:54 PM. Sea surface temperature at a single buoy can differ by several degrees from the water at a beach or in a shallow bay nearby.

What do the wind speeds in knots mean?

One knot is 1.15 mph. The National Weather Service issues a small craft advisory for sustained winds of roughly 22–33 knots or hazardous seas, a gale warning at 34–47 knots, and a storm warning at 48 knots and above. Exact advisory thresholds vary by forecast office and by water body — a bay reaches dangerous chop at a lower wind speed than open ocean.
