Marine Weather and Tide Forecast for El Combate, PR

.Short Term(Today through Wednesday)...
Issued at 240 AM AST Mon Feb 9 2026

Fair weather conditions prevailed overnight, despite persistent mid-to-upper level cloud cover associated with the nearby frontal boundary. Radar transitioned into Clear Air Mode, confirming the lack of meaningful precipitation. Only a few brief trade-wind showers were observed over exposed northern coastal areas, driven by strengthening northerly to northeasterly winds, with no measurable impacts. Winds were breezy at times, averaging around 10 mph across coastal Puerto Rico and peaking near 15–20 mph across the U.S. Virgin Islands. Overnight temperatures dropped into the upper 50s across higher elevations, while coastal and island locations remained in the upper 70s, with additional cooling likely toward sunrise.

The frontal boundary will remain stalled to the southeast while high pressure moves off the U.S. East Coast into the Atlantic.
This will tighten the pressure gradient and lead to strengthening northerly to north-northeasterly winds, which will be the main hazard today, especially along exposed coastal areas. Otherwise, fair and generally dry conditions will continue, favorable for most outdoor activities. Cooler air behind the front will keep temperatures on the cool side, with some variability as the region remains between two different air masses. A strong trade-wind inversion will limit cloud growth and keep showers shallow through most of the day, though it will begin to weaken tonight. Any shower activity will remain brief and limited to windward areas, while steadier activity stays mainly over the Caribbean waters and near Saint Croix, with minor or no impacts expected over land.

High pressure will continue strengthening and shifting eastward into the central Atlantic, keeping winds as the primary concern.
Winds will turn northeasterly by Tuesday evening and increase to 20–25 knots, especially across coastal areas and higher terrain, before turning more easterly by Wednesday. Tuesday will remain cool under persistent northerly flow, with temperatures gradually warming on Wednesday as winds shift east. The trade-wind inversion will weaken significantly or nearly disappear on Tuesday as an upper-level disturbance passes, then rebuild by Wednesday. Even so, fair weather will largely persist, with only brief, wind- driven showers near the stalled frontal boundary, the Caribbean waters, Saint Croix, and windward areas. Rainfall impacts are expected to remain minimal, with strong winds remaining the dominant hazard, particularly Tuesday into early Wednesday.



.Long Term(Thursday through Monday)...
Issued at 240 AM AST Mon Feb 9 2026

A surface high-pressure system centered over the central Atlantic shifting eastward will support light to moderate southeasterly winds across the region. As the high continues to move eastwards, abundant moisture associated with the remnants of a frontal boundary will lift northward from Caribbean waters, reaching the area through at least late Friday.

By Friday, an upper-level trough will approach from the northwest, increasing atmospheric instability. The combination of southeasterly flow and deep moisture will enhance the potential for widespread showers throughout the long-term period. Precipitable water (PWAT)
analysis shows values climbing from 1.25 inches on Thursday to 1.75 inches by Friday, ranging from seasonal to above-normal climatological levels.

Consequently, morning showers are expected across eastern Puerto Rico and the U.S. Virgin Islands, followed by afternoon convective activity over central and northwestern Puerto Rico. While temperatures at the 925 mb level will remain below normal through Friday, they are expected to rise on Saturday, bringing warmer conditions back by the weekend.

MARINE
Issued at 240 AM AST Mon Feb 9 2026

A surface high pressure moving off the US coast will begin to yield moderate to fresh northerly winds through Tuesday. A weak frontal boundary will linger over the Caribbean waters and the Anegada Passage during the next few days, while another weak front moves into the offshore Atlantic waters. This will promote mostly cloudy skies across portions of the regional waters. A large, long period northwest swell will bring hazardous seas from through midweek. Small Craft Advisories are in effect for most local waters exposed to the NW swell.



BEACH FORECAST
Issued at 240 AM AST Mon Feb 9 2026

A large, long period northwest swell will gradually spread across the Atlantic waters and passages during the next few days. This swell will cause large breaking waves between 10 and 15 feet along the northwest to northeast coasts of PR, Culebra and the northern USVI. High surf conditions, life-threatening rip currents, and minor coastal flooding is expected with this large breaking wave action.
Hazardous swimming conditions will last through midweek. A Coastal Flood Advisory, High Surf Advisory, and High Rip Current Statements are in effect.

Beachgoers are urged to continue monitoring forecast updates and to follow all local advisories, warnings, and guidance from lifeguards and local officials as conditions continue to deteriorate.
