Marine Weather and Tide Forecast for Dayton, TX

DISCUSSION
Issued at 1239 PM CST Mon Dec 15 2025

We'll see one more night with readings in the 30s to low 40s under mostly clear skies and light winds. Northeast parts of the CWA may experience a light freeze, but chances are pretty low for the rest of us. Increasing cloudiness and a gradual warm-up is anticipated Tuesday-Thursday as high pressure moves away from the region and SE-S-SW winds resume off the Gulf. Look for some patchy fog development Tuesday and Wednesday nights. Mid-upper trough will move ewd across the state Tue night and Wed and should provide chances for some scattered showers across the area as well. The next cold front, not as impressive as the last, will push through the region Thursday afternoon and off the coast Thurs evening.
Southwesterly llvl flow in advance should limit overall rain chances along this boundary (not zero...but low). After a day or so of seasonable wx in its wake, we'll see another warm-up this weekend with overnight lows trending back into the 60s and daytime highs flirting with 80F. 47

Cotto

MARINE
Issued at 1239 PM CST Mon Dec 15 2025

Winds and seas will continue to diminish, and will gradually veer around to the east and southeast tonight and Tuesday as high pressure tracks away from the region. Patchy fog is a possibility in the northern bays Tuesday and Wednesday nights. Light onshore flow continues in advance of the next front expected to push off the coast Thursday night. A brief period of caution/advisory flags may be needed behind this front, but it should not be as significant in terms of winds/seas as this past front. Onshore winds resume Friday night. We will need to keep an eye out for some sea fog development this weekend as a warmer airmass returns. 47
