Marine Weather and Tide Forecast for Galena Park, TX

SHORT TERM
(Today through Tuesday Night)
Issued at 235 AM CDT Mon Apr 28 2025

Until the last few hours of the short term period on Tuesday night, ridging remains the name of the game of the short term forecast. As a result, we're basically just rolling right along with fair weather, onshore winds, and warm conditions. In fact, yesterday we managed to snag a daily record high minimum temperature at Galveston, to give a bit of an image of how warm our nights are right now. While not full summer, these are definitely nights that remind us that hot, muggy summer nights are nearly upon us. In the afternoon, we've tapped the brakes somewhat. This ridging is still not exceptionally strong, and we do have overnight stratus to break up. So while not as close to records as the overnight lows are, we're still managing to get up higher into the 80s than area averages are for this time of year, and that should continue today and tomorrow.

Beyond the temperatures, onshore winds continue, but I anticipate them to be a little bit stronger as we draw closer to the approaching cold front (maybe reaching? More on that in the long term) and the pressure gradient will be getting tighter. I wouldn't anticipate something that threatens any sort of wind advisory, but still looking for afternoon peak winds solidly into the teens, with some gusts into the lower half of the 20s. Though very infrequent, it does appear likely to see an occasional gust around/above 25 mph west of the Houston metro.

Finally, though fair weather is going to largely dominate this period, we do have ample moisture and persistent onshore flow that tends to have a bit of natural isentropic lift for our area. As a result, there may be some fast, brief, light sprinkles particularly at the coast in the pre-dawn and very early morning hours. Because accumulations would be just a trace and not measurable, it's not enough to really push PoPs up more than just a few percent
But
if you have a really early commute and get a sprinkle for several seconds, it won't be the biggest surprise for you.

LONG TERM
(Wednesday through Sunday)
Issued at 1225 AM CDT Mon Apr 28 2025

By daybreak Wednesday there will be an upper-level trough moving through the Four Corners region with a weak surface low developing in the Central Plains by Wednesday evening. While the main upper- level trough will be to the northwest, weak shortwaves out ahead of it, daytime heating, and plenty of moisture around could lead to some isolated showers or thunderstorms across SE Texas Wednesday afternoon. The cold front/dry line associated with the surface low will be approaching SE Texas Wednesday night into Thursday morning increasing the rain chances with it. However, as we get later and later into the Spring season/approaching summer, these cold fronts are getting weaker and weaker, and thus become less likely of fully clearing (or even entering) our area. Guidance continues to trend for this front to stall out near the Piney Woods/Brazos Valley region. This will keep the highest rain chances north of I-10 Wednesday night into Thursday morning. This boundary will be hanging around just to the north of the region through the end of the week.
There will also be passing shortwaves aloft through the weekend, which combined with the nearby boundary and abundant moisture will lead to continued rain chances through Sunday.

Warm and humid conditions will persist through next weekend. High temperatures will be in the mid to upper 80s most days for inland areas (coastal areas in the low to mid 80s). Thursday will be the warmest day as increased WAA ahead of the stalled boundary to the north will bring temperatures up into the low 90s for areas west of I-45 but north of I-10. Overnight lows will be in the upper 60s to mid 70s through the long term.

AVIATION
(12Z TAF Issuance)
Issued at 642 AM CDT Mon Apr 28 2025

Another morning with a wide range of flight conditions across the area, but all the TAF sites are currently bouncing between MVFR and VFR, depending on whether the lower deck of clouds is SCT or BKN. Expect this for a handful of hours before widespread VFR prevails, with strengthening winds 10G20(ish) out of the S/SE to follow. Gusts tail off after sundown, with stratus returning overnight along with MVFR conditions late tonight.

MARINE
Issued at 1225 AM CDT Mon Apr 28 2025

Onshore flow of 7-15kt will persist through much of this week with gusts to 20kt becoming possible Tuesday through Thursday. Low seas of 2-4ft will persist through Tuesday morning, increasing to 4-6ft Tuesday through Thursday as the winds get slightly higher. Small craft will likely have to exercise caution at times beginning Tuesday. Minimal rain chances exist through Wednesday, but an approaching boundary may bring showers and thunderstorms Thursday with additional rain chances through the weekend.

The persistent onshore flow will lead to increasing risk of strong rip currents through the week with rip current statements possibly needed by Tuesday. Abnormally high astronomical tides and the increasing onshore flow will lead to higher than normal tides with high tide on Tuesday morning rising to around 3ft above MLLW and around 3.5ft above MLLW for high tide on Wednesday.
