Marine Weather and Tide Forecast for Beaumont, TX

SHORT TERM
(Tonight through Thursday night)
Issued at 507 AM CST Tue Nov 11 2025

Surface high pressure is currently centered almost directly overhead, resulting in light northerly to calm winds and clear skies. This setup will allow for the coldest conditions of this brief cold snap, with overnight lows expected to fall into the upper 20s to 30s.

A Frost Advisory is in effect for Jefferson and S. Orange Counties as well as S. Calcasieu, S. Jeff Davis, and Cameron Parishes.
While subfreezing temperatures are not expected in these areas, frost formation is likely on exposed outdoor vegetation. Elsewhere in the CWA, a Freeze Warning remains in effect where at or below subfreezing temperatures are anticipated.

The surface high pressure will quickly shift east on Tuesday, allowing southerly flow to return by lunchtime. From Tuesday onward, we will see a rapid warming and moistening trend as a warmer Gulf airmass advects into the area. By the end of the short term, MaxTs will rebound into the mid 70s to lower 80s while MinTs only fall to the mid 50s to lower 60s. Dewpoints will also see a steep rise, but despite this increasing moisture, PoPs will remain near zero.

LONG TERM
(Friday through next Monday)
Issued at 507 AM CST Tue Nov 11 2025

The warm and dry pattern holds until the weekend, with little change expected weather wise. Temperatures will remain well above seasonal averages and rain chances will be minimal. The surface high pressure will be firmly anchored over the SE CONUS, maintaining prevailing southerly flow for several days. Flow aloft is forecast to be predominantly zonal during this period.

We can look forward to a pattern change late this weekend into early next week. By Saturday into Sunday, a cutoff upper low will be centered near the AZ/MX border. Closer to the surface, a tightening pressure gradient will form between the aforementioned high pressure to our east and low pressures advancing from the west. This gradient will lead to increasing and potentially quite gusty southerly flow. This enhanced moisture and lift may support isolated to scattered showers, particularly Sunday.

Sunday into Monday, the upper low and an associated cold front are expected to be positioned over the Southern Plains. Isolated to scattered showers and thunderstorms are anticipated ahead of and along this boundary. While it is far too early to talk about specific QPF amounts, current guidance shows high confidence in rainfall: there is at least an 85 percent chance of receiving measurable (0.01+ inches) rainfall and at least a 65 percent chance of receiving a wetting rain (0.25+ inches).
