Marine Weather and Tide Forecast for Santa Fe, TX

DISCUSSION
Issued at 1251 PM CDT Tue Aug 4 2026

No significant changes were made to the ongoing forecast. With the exception of an isolated seabreeze/baybreeze shower or thunderstorm, subsidence and modest moisture levels should keep rain chances fairly low for the vast majority of the region. As the days progress Thursday into early next week, we should see heights fall just a touch across our coastal areas as the western ridge repositions just a bit further north. This, along with a developing fetch of SE llvl winds and higher PW's should allow for some better rain chances (mainly just scattered diurnally driven coverage) for our southern 2-3 tiers of counties. High temperatures should trend down a few degrees as well with the SE flow and more cloud cover. 47
