Marine Weather and Tide Forecast for Hackberry, LA

DISCUSSION
(Tonight through next Saturday)
Issued at 1134 PM CDT Sat Jun 13 2026

A very warm and humid night is ongoing across the region. The current temps and humidity feels more like August or late July than mid June.

The warm and moist air mass is being driven into SE TX and SW LA around the subtropical ridge stretching into the gulf from the Atlantic and ahead of a cold front that is dropping south across the plains. A weak area of low pressure over the southern gulf near Tampico, Mexico is moving inland tonight or very early Sunday/today.

Aloft, convection has been suppressed over the past couple of days by a ridge.

Today the weak gulf low will move into Northeast Mexico. Moisture will be pulled north into the local region ahead of the approaching cold front and around the subtropical ridge. The upper ridge will also be eroded by a short wave passing across the Mississippi Valley. While the day will start out warm, humid, and fairly cloud free, scattered to widespread storms are anticipated by afternoon, especially across inland areas. Lower rain chances are expected across Lower Acadiana today.

The cold front is forecast to move into the region and stall Monday into Tuesday. Very high PWAT values along and ahead of the boundary indicate that any storms that train will be capable of producing localized flooding with very high rain rates today, Monday, and Tuesday.

Tuesday into Wednesday the frontal boundary may become more diffuse, decreasing the focus for convection. However another round of heavier rain may be possible by late week. The weak low currently over gulf is forecast to drift north then northeast by mid week. While chances of any development into an organized tropical cyclone looks unlikely, heavy rain may be a concern as the plume of deep moisture passes overhead Wednesday and Thursday.
Tides along the coast may run between 1 and 2 feet above normal during the period.

MARINE
Issued at 1134 PM CDT Sat Jun 13 2026

An onshore flow of 10 to 15 kts will remain in place into mid week, however rain chances will increase as a cold front drifts in and stalls. A weak low may traverse the coastal plain from mid to late week increasing the onshore flow late Wednesday into Thursday.

FIRE WEATHER
Issued at 1134 PM CDT Sat Jun 13 2026

A weak frontal boundary will move into the region and stall near the coast during the first half of the week. This front is not expected to produce a wind shift, but it will act as a focus for numerous showers and thunderstorms from Sunday through most of that work week. Widespread soaking rains are anticipated.
