Marine Weather and Tide Forecast for Port Lavaca, TX

DISCUSSION
Issued at 133 AM CDT Fri Oct 16 2026

A strong cold front can be seen via satellite and radar moving south to southeast across the Hill Country. The cold front is expected to move through S TX later this morning, finally bringing some relief from the heat. The cooler and drier conditions will be more noticeable tonight. A pleasant weekend is in store for S TX with highs in the 70s and lows in the 50s to low 60s. Temperatures begin to warm back up early next week.

Rain chances associated with the cold front will be highest across the Rio Grande Plains with up to 55% chance and across the gulf waters with up to 70% across the offshore waters. The Brush Country, Coastal Plains and Victoria Crossroads have a 15-30% chance of mainly showers. A few thunderstorms will be possible. The rain is expected to end from northwest to southeast this afternoon.

Strong north winds behind the cold front will be a concern with gusts up to 35-40 mph. A Wind Advisory is in effect across S TX starting this morning. Winds are expected to decrease below advisory levels initially across the western areas this afternoon, then across the eastern areas tonight. The islands are expected to remain at advisory levels through Saturday morning.

Gale conditions are expected later this morning as the cold front pushes offshore, and will likely continue through Saturday morning to early Saturday afternoon. Seas are forecast to build to 8-13 feet. Winds begin to relax Saturday afternoon and evening, but will remain at advisory levels through Saturday evening.

Another concern will be coastal flooding. The strong northerly winds and large seas across the gulf waters and swell periods of 8-9 seconds will likely lead to minor coastal flooding during times of high tide. A Coastal Flood Advisory is in effect this afternoon through Sunday morning. In addition, the long period swells will be conducive for a moderate rip current risk today through Saturday.
The north winds along the shore tend to negate the rip current risk, but given the long period swells and large seas, should lead to a moderate risk.
