Marine Weather and Tide Forecast for Port Aransas, TX

DISCUSSION
Issued at 110 PM CST Sat Jan 17 2026

High pressure settling into the area tonight with light winds will set the stage for radiational cooling. This should allow temperatures to dip below freezing (upper 20s to lower 30s) across inland areas of South Texas and just above freezing along the coast (mid to upper 30s). Confidence on exactly how low temperatures may get are still a little iffy as models are differing from the upper 20s to low 30s. Regardless of what the low temperature ends up being, it's going to feel cold as the sun rises Sunday morning. Wind chill values (feels like temperatures) are expected to drop into the 25-30 degree range inland and 30-40 degree range along the coast.
Therefore, there is a Freeze Warning or inland South Texas.

As we head into next week, temperatures rebound to near normal levels and hang around through mid-week before warm temperatures return late this week. A coastal trough is expected to develop Tuesday night and hang around through Wednesday before moving off to the northeast Wednesday night through Thursday. This feature will finally bring rain chances back to the forecast with low (25-35%)
chances Tuesday night increasing to medium (40-65%) Wednesday before dropping back to low Wednesday night. The best chances for wide spread rain across South Texas will be Tuesday night into Wednesday with rain chances Wednesday night sticking close to the coast.
Although rain chances will increase, it doesn't appear to be beneficial rain as storm total accumulations are expected to peak near 1".
