Marine Weather and Tide Forecast for Port Aransas, TX

DISCUSSION
Issued at 123 PM CDT Fri Aug 14 2026

Beyond this afternoon's few showers and storms over the Coastal Plains from the trough riding the southwestern periphery of the ridge ushering moisture, mid-level ridging will flatten out over the southern CONUS and lead to near normal moisture, hot, and generally rain-free conditions into the middle of next week. Heat indices will peak around 110 over the Coastal Plains daily, with max temperatures ranging from 90-105 degrees and low temperatures in the mid to upper 70s. Therefore, a moderate to major risk of heat-related impacts will remain South Texas' greatest weather concern.

Heading into the latter part of next week, a mid to upper level trough is expected to push eastward across the Midwest to Great Lakes region, potentially reflecting all the way south into parts of Texas. Currently, any impacts or increased rain chances remain north of our area.

AVIATION
(18Z TAFS)
Issued at 123 PM CDT Fri Aug 14 2026

A few showers and thunderstorms are currently ongoing across the northern Victoria Crossroads and inland Coastal Plains, mainly impacting VCT over the next hour or so. Additional showers may develop westward as the seabreeze pushes through, but confidence is too low to include at this time. Breezy southeasterly winds will persist through this evening before weakening, leaving MVFR potential over VCT between 10-14Z. Diurnal winds pick up by mid to late morning hours, near the end of the forecast.
