Marine Weather and Tide Forecast for Rockport, TX

DISCUSSION
Issued at 149 AM CDT Fri Apr 17 2026

Forecast remains largely unchanged with persistent warm temperatures and breezy conditions once again tomorrow. With the strengthening low pressure northwest, we will likely bump winds up a notch, but think we should still generally stay below wind advisory criteria (30mph sustained/40 mph gust)

The interesting part of the forecast begins Saturday with a relatively strong frontal boundary for this time of year, enhanced by a deep mid-level trough in the middle of the country. Showers and possibly a few thunderstorms are expected to accompany the front, but with meager cape and only marginal shear, strong storms don't look especially likely. Most of the convection will likely be elevated behind the front. Expect breezy conditions behind the font with very wind conditions along the coast and into the open waters.
Temperatures Sunday and Monday with be mainly in the 70s, and some locations may not even make 70.

The Sunday through Tuesday period could be a bit interesting with a few ingredients suggesting our rain chances remain elevated through this period. First of all, a fairly good isentropic lift pattern sets up while surface winds remain northeast to east and winds above the surface shift back around to the southeast. A weak coastal trough developing will also help to keep moisture pushing into the region. Additionally, in the mid-levels we'll a couple of shortwaves cloud enough to impact the area. Will this bring a lot of rain? Not as much as we need, but an area wide average over half an inch is definitely in the cards with localized totals more an an inch. Looking at the high end of things (10% probability of exceedance), we could see some spots of 2 inches or more.
Considering this is over a 3 day period, flash flooding concerns are unlikely at this time.

Gradually warming conditions are expected as we head through next week with dry conditions after Tuesday.

AVIATION
(06Z TAFS)
Issued at 149 AM CDT Fri Apr 17 2026

At time of issuance, a mix of VFR/MVFR CIGs is seen over South Texas, with MVFR conditions confined to eastern sites. However, brief instances of MVFR may been seen across the Brush Country around sunrise, so TEMPOS were included for COT/LRD. These conditions will persist through 15-17z on Friday when the CIGs scatter leading to VFR conditions which will continue through the afternoon and early afternoon hours. Southeasterly winds will also increase around this time, with sustained winds between 15-20 knots and gusts up to 25-30 knots. Gusts will diminish through the evening, with the return to MVFR CIGs again Friday night into Saturday morning.
