Marine Weather and Tide Forecast for Beaumont, TX

DISCUSSION
(Today through Monday)
Issued at 1221 AM CDT Tue Jun 9 2026

Large area of upper high pressure ridging covers the southeast US by a wide margin. Anomalously humid airmass remains in place, and beneath this high, it's very warm, very humid and rather miserable outside. So it goes for the first week of Meteorological Summer!

Little change will be had over the coming days as the pattern is rather stagnant. Some variations to the ridge over the coming days should result in 10 to 20 percent chance of afternoon showers (an isolated thunderstorm cannot be ruled out.) But largely, the next week will be a wash-rinse-and repeat kind of forecast. Each day will see temps in the 90s, and with daily RH values around 60 percent, that heat index will still come into the low 100s to as high as 108F for inland areas (where high temps will squeak into the low to mid 90s).

The longer we go into a heat wave like this, the more the heat stress acts on the body. Maintain good heat safety as much as possible each and every day: hydrate, take frequent breaks, check on those vulnerable groups around you.

As for rain chances, there are some low end PoPs from tomorrow to the end of the week. This is to account for the seabreeze showers which can make their way up and past the ridging. As the high meanders around, there could be pockets of daytime showers/iso storms to pop up later in the day. The summertime normal.

AVIATION
(06Z TAFS)
Issued at 1221 AM CDT Tue Jun 9 2026

VFR conditions with light southeasterly winds will prevail across the area tonight. Some patchy light fog/mist may develop at times tonight, more likely at AEX, but any fog that develops will dissipate quickly with sunrise. Isolated convection will be possible along the seabreeze boundary, which could bring a shower or thunderstorm to BPT/LCH/LFT/ARA in the afternoon, but confidence is too low to include in the TAFs at this time. Outside of storms, 5-10 kt southeast winds and VFR conditions are expected for all sites through the remainder of the forecast period.

MARINE
Issued at 1221 AM CDT Tue Jun 9 2026

High pressure ridge will persist over the northeast Gulf during the period brining about a prolonged period of light to breezy onshore flow, low seas and mostly clear conditions.

The ridge starts to erode slightly into the end of the work week which could help bring some low end rain chances back to the nearshore waters.



FIRE WEATHER
Issued at 1221 AM CDT Tue Jun 9 2026

Anomalously warm and humid conditions will persist over the coming days with only low to occasionally breezy south winds to offer some reprieve. High pressure settled on top of the northeast Gulf will keep majority of rain chances from the forecast, but afternoon seabreeze showers with an isolated storm or two will be possible near the coastal areas.
