Marine Weather and Tide Forecast for Seabrook, TX

DISCUSSION
(Rest of Tonight through Monday)
Issued at 1220 AM CDT Tue Jun 17 2025

Tranquil conditions are expected during the overnight to early morning hours with mostly clear to partly cloudy skies and low temperatures generally in the mid to upper 70s inland and the upper 70s to lower 80s along the coasts.

Slightly drier conditions expected Tuesday as the eastern edge of the mid-level ridge located over northern Mexico extends closer into Southeast TX on Tuesday and slightly lower surface PWs (between 1.4 and 1.8 inches) help limit shower and thunderstorm development during the day. Models also show the upper level trough axis moving into the LA region in the morning, allowing for the ridge to have a stronger influence. Although we are expecting lower chances of rain, there might still be enough heating and instability to support some showers and thunderstorms, in particular over areas near and south of I-10 during the afternoon to early evening hours. Stronger storms may be capable of producing gusty winds, periods of heavy rain, and small hail. The heavy rain could lead to ponding of water along roadways and poor drainage areas.

For the rest of the area, expect sunny to partly cloudy skies and southerly winds at around 10 mph. High temperatures will be in the upper 80s to lower 90s and heat indices will range between 100-105 deg F. Make sure you take extra precaution if you plan to spend time or work outdoors and practice heat safety. Take multiple breaks, limit sun exposure, and drink plenty of fluids.
Never leave children or pets unattended in vehicles. If it's too hot for your hands, then it's too hot for their paws. Rain chances decrease Tuesday evening as we loose heating and instability. The low temperatures will be slightly warmer and range between the mid to upper 70s for most of the inland areas.

An upper-level trough is expected to move across the Southern Plains Wednesday into Thursday, which may give us a better chance for rain. However, the presence of the mid-level ridge may be enough to limit most of the shower and thunderstorm development. It still looks like Thursday may be the better day for rain chances, thus, continued with the NBM solution and kept 10-30% PoPs for Wednesday and 20-40% for Thursday. The high temperatures will remain in the upper 80s to lower 90s and heat indices will be in the lower 100s. Breezy conditions is also expected mid-week as a low level jet develops over Southeast TX.

For the end of the week and into the weekend, expect a typical summer-like weather pattern with isolated to scattered showers and storms developing over the water and coastal locations during the morning hours and then expanding inland during the afternoon.

AVIATION
(00Z TAF Issuance)
Issued at 614 PM CDT Mon Jun 16 2025

Some lingering isolated thunderstorms remain over parts of SE Texas this evening, mainly near SGR. However, numerous outflow boundaries from storms earlier today continue to propagate across the area could result in variable wind shifts. These wind shifts will not last long, about 30 minutes or so, before southerly winds redevelop and persist through the rest of the period. The storms that still remain currently are expected to weaken and dissipate by sunset. Generally, VFR conditions will prevail through the period, but a period of MVFR conditions are possible at CLL, UTS, and CXO late tonight into early Tuesday morning. Scattered low cloud (around 2000ft) will reach all the way to the coast, and there could be brief periods of these clouds becoming more BKN, but generally VFR conditions will prevail for terminals along and south of I-10.

Warm and humid conditions are expected again on Tuesday, so pop-up afternoon thunderstorms will again be possible. Coverage should be less than today, but cannot out rule an isolated storm impacting a terminal at some point in the afternoon.

MARINE
Issued at 1220 AM CDT Tue Jun 17 2025

Light to occasionally moderate onshore winds and seas of 2 to 4 feet are expected throughout the next several days. Winds will slightly increase late Tuesday into late Wednesday as the pressure gradient tightens and a low level jet develops. Seas may rise to around 5 feet for the offshore waters. Caution flags will likely be needed. Persistent onshore flow will result in a high risk for strong rip currents along the Gulf facing beaches.

Chance for showers and thunderstorms can be expected each day.
Some storms could briefly lead to higher winds and elevated seas.
Brief waterspouts cannot be ruled out.
