Marine Weather and Tide Forecast for Beaumont, TX

SHORT TERM
(Today through Thursday night)
Issued at 407 AM CDT Tue May 13 2025

Upper low has moved off to the northeast and now sits near Nashville, TN. That leaves us with dry, northwesterly flow and beneath the subsident edge of the system. Ridging has also developed across the north central Gulf, bringing about southerly winds.

Moisture will return in force today, in fact it's already increased by about 3F at the office overnight. Increased humidity, combined with clear skies and dry air aloft, will result in very warm temperatures today through the rest of the short term period.
Expect highs in the mid to upper 80s along coastal areas to low 90s inland. The range in temps won't really change, but it's going to feel warmer each day to the next.

Over the next several days, there will be increase in winds as the pressure gradient tightens between Gulf high and passing frontal systems to the north. A light breeze will be possible today, but tomorrow should be breezy to even gusty at times thanks to a passing shortwave in east Texas. Current forecast winds on Wednesday are borderline for Wind Advisory. One has not been issued at this time but may come with a later forecast update.

Cloud cover appears to return late Wednesday into Thursday with this passing system, however this does not appear to impact temperatures in any appreciable way.

LONG TERM
(Friday through Tuesday)
Issued at 407 AM CDT Tue May 13 2025

High pressure remains staunchly in charge of the forecast through the longterm period. Previously, there were low end rain chances on Saturday, but latest guidance has trended upper ridging stronger than before. This shunts rain chances further north, and ultimately out of the forecast area.

Temperatures in the low to mid 90s can be expected each day, with no improvement in moisture. This means we're looking at a prolonged period of very very hot weather, relative to this time of year.

See Climate section for more information regarding the hot weather.

AVIATION
(18Z TAFS)
Issued at 1224 PM CDT Tue May 13 2025

The pressure gradient between an area of low pressure over the southern plains and a high pressure area over the eastern gulf will keep southerly flow elevated overnight before increasing further Wednesday with guts of up to 30 knots possible by late Wednesday morning. SCT fair weather cu this afternoon will give way to mostly clear skies overnight and a few high clouds Wednesday morning.

MARINE
Issued at 407 AM CDT Tue May 13 2025

Southerly flow has returned with high pressure expanding westward from Florida. A weak shortwave is expected to move across east Texas and west Louisiana from this afternoon into Wednesday. This is expected to bring about strong gradient winds and thus a Small Craft Advisory has been issued for 0 to 60 NM waters from tonight into Wednesday afternoon. Ridging builds in fully through the mid week, with a dry forecast through the rest of the work week.
Periods of elevated winds will be possible with the passing of low pressure systems to the north.

CLIMATE
Issued at 407 AM CDT Tue May 13 2025

Heat Risk is a somewhat new product (still experimental) that is now picking up more interest. It combines many factors such as how unusually above- normal temps are, forecasted humidity, time of year, the duration of this unusual heat and if these temperatures pose an an elevated risk to the population (such as heat stroke or stress). The Heat Risk over the area increases to Moderate (level 2 of 5) starting Thursday then increases to Major (Level 3 of 5) for some areas Friday and beyond.

Moderate impacts can be: impacts possible to both those sensitive to heat, especially without AC or proper hydration, and to those in some health systems and heat-sensitive industries.

Major impacts can be: impacts to anyone without effective cooling or hydration and expected impacts to some health systems, heat- sensitive industries and infrastructure.

Some offices have suggested decreasing local Heat Advisory criteria in order to properly inform the public, considering heat indices are not expected to reach traditional criteria. This is a possibility and will be discussed internally.

No matter, please please prepare for an extended period of unseasonable and impactful heat for at least the next 7 days.
