Marine Weather and Tide Forecast for Angleton, TX

DISCUSSION
Issued at 1114 PM CDT Thu Apr 16 2026

More of the same is expected through Friday with continued warm and humid conditions thanks to southerly flow at the surface and southwesterly flow aloft. There will be bit of a tightening of the pressure gradient over us on Friday as we get sandwiched between high pressure over the eastern Gulf and a low pressure system exiting into the Central Plains to our northwest. This will lead to some gustier winds during the afternoon and evening hours, with gusts to 20-25mph possible. High temperatures continue to be in the mid to upper 80s for most of the region on Friday with overnight lows in the upper 60s to low 70s Friday night.

The aforementioned low pressure system moving into the Central Plains on Friday will continue to push eastward on Saturday with its associated cold front moving through SE Texas Saturday afternoon/evening. We may begin to see light streamer showers as early as Saturday morning, but then expecting scattered showers and isolated thunderstorms Saturday afternoon and evening ahead of an along the cold front. Moisture is expected to surge to around 1.7-1.9" ahead of the cold front, so localized downpours will be possible with any thunderstorms that develop. Minor urban and small stream flooding may occur if these thunderstorms develop over an area of poor drainage. WPC maintains a Marginal Risk (level 1 of 4) for areas along and north of I-10. Lingering moisture behind the front may lead to isolated showers sticking around the coast into Sunday morning. The FROPA will also usher in breezy northerly winds (gusts to 20-25mph in land, up to 30mph at the coast) Saturday night into Sunday afternoon.

Cooler weather is expected Sunday through Monday with daytime highs in the low 70s and overnight lows in the 50s. Southerly flow returns by Monday night leading to a gradual increase in temperatures through the remainder of the week: highs in the mid to upper 70s on Tuesday, low 80s on Wednesday, and possibly mid-80s by next Thursday.

Rain chances do return late Monday into Tuesday, and again Wednesday into Thursday, as a series weak disturbance moves across the Southern Plains into the Gulf Coast.

Another rinse and repeat forecast for this package. Southerly winds around 8-12kt will persist through the evening, then decrease to 5-8kt overnight inland and then remain near 10kt at the coast. MVFR conditions will return to the region between 5-7z with CIGs down to around 1500ft (and some scattered lower clouds possible). These conditions will persist through 15-17z on Friday when the CIGs scatter out giving way to VFR conditions that will continue through the day. The southerly wind are expected to increase back to around 10-15kt during the mid-morning, and then wind gusts to 20-25kt will develop during the late morning hours and continue through the evening. The gusts will diminish through the evening, and then the return to MVFR conditions is likely again Friday night into Saturday morning.

Small craft should continue to exercise caution as moderate south-southeasterly winds (15-20kt) and 3-5ft seas persist through Friday night. A tightening pressure gradient across the region may lead to gusts to 25kt Friday afternoon/evening, and if these gusts are frequent enough then a Small Craft Advisory may be issued.

A decrease in the winds is expected Saturday morning ahead of an approaching cold front. Scattered showers and isolated thunderstorms will be possible ahead of and along the cold front's passage. It is expected to push through the coastal waters Saturday evening into Saturday night ushering in strong north to northeasterly winds that will persist into late Sunday. Sustained winds of 20-30kt are expected with gusts to 35kt possible, which will lead to building seas of 7-10ft seas. Small Craft Advisories will be likely Saturday night into Sunday evening, but a Gale conditions cannot be ruled out. Winds gradually lower and veer through Monday with southeasterly flow expected by Monday night.

The persistent onshore winds will lead to increased wave run-up and elevated tides through Saturday (high tides running around 3-3.3ft above MLLW). There will also be a moderate to high risk of strong rip currents along Gulf-facing beaches.
