Marine Weather and Tide Forecast for Sabana Eneas, PR

.Short Term(This evening through Thursday)...
Issued at 110 PM AST Tue May 5 2026

Partly cloudy skies prevailed across the U.S. Virgin Islands and eastern Puerto Rico, including Vieques and Culebra, during the morning hours, accompanied by a few passing light showers.
Meanwhile, clearer skies dominated western Puerto Rico early in the day before gradually transitioning to partly cloudy conditions as the morning progressed.

For the rest of the afternoon and overnight hours we anticipate the development of showers and isolated lightning due to the proximity of a trough, in combination with the available moisture, diurnal heating, and local effects. This activity will mainly affect windward areas of eastern Puerto Rico and the U.S. Virgin Islands, with probabilities generally remaining in the limited to low range.
On Wednesday afternoon, localized convective activity is expected to develop once again, particularly across the northwestern quadrant of Puerto Rico. However, moisture availability will remain the primary limiting factor despite some lingering dynamical instability aloft, resulting in moderate probabilities of precipitation. These outcomes will depend on the timing and extent of drier air intrusions, which may re-establish inversion caps and suppress convection.

By Thursday, a more stable pattern is expected to take hold as drier air filters into the region, further limiting convective development. This will likely result in the least active day of the period, with low probabilities of precipitation. Only isolated, brief showers are expected across windward areas overnight, with minimal afternoon activity across the interior and western sections of Puerto Rico.

.Long Term(Friday through Tuesday)...
Issued at 450 AM AST Tue May 5 2026

East to east-northeast flow to start the period will steer patches of both drier and more humid air towards the region. Precipitable Water (PWAT) values will generally be at below normal to low end normal values for this time of the year. Available moisture will also be shallow, mainly below 800 mb. With this below normal to normal moisture and increasing subsidence (an upper level trough will be moving away from the region to start the period and mid- level ridging will build) a general reduction in shower activity and rainfall coverage is forecast. A limited heat risk is also forecast for most of the period, affecting sensitive individuals and individuals with prolonged exposure and/or inadequate hydration.
Current model guidance suggests a more easterly steering flow to start the next week, veering to become more easterly to east- southeasterly to start the next workweek and continuing to bring patches of both drier and more humid air. Up to breezy conditions will be present, particularly to start the weekend onwards.

This will result in a limited non-thundersstorm wind risk, with gusts up to around 25 mph at times at coastal and windward areas.
Unsecured items could blow around. Shower activity can continue to reach windward sectors of the islands during the morning and overnight hours while diurnal heating and local effects can promote afternoon convection over mainly interior to western PR with steering flow each day determining a more NW or SW movement.
Low concentrations of Saharan Dust will reach the area while the bulk of a Saharan Air Layer will stay south of the local islands.
Under breezy conditions, increasing temperatures and with patches of drier air approaching, the potential for elevated fire danger remains, stay tuned for any future updates.

AVIATION
(18Z TAFS)
Issued at 110 PM AST Tue May 5 2026

Mostly VFR condt are expected to prevail across all terminals.
However, brief MVFR possible with VCTS possible over TJBQ. VCSH possible over TJSJ, TIST, TISX after 05/18Z. Winds will remain around 12kts with occasional higher gusts, becoming light and variable overnight.

MARINE
Issued at 110 PM AST Tue May 5 2026

Surface high pressures and a frontal boundary over the Atlantic will promote gentle to moderate easterly to southeasterly winds through at least early Thursday, then becoming more easterly to northeasterly. By the weekend, winds are expected to increase to moderate to fresh levels across the regional waters. Seas will range between 2 and 4 feet, occasionally higher due to a combination of local wind waves and a few pulses of a small, long- period northeasterly swell spreading across the Atlantic waters.
Overall, conditions will be favorable for small craft, though operators should exercise caution at times due to wind-driven seas and passing showers that may produce locally higher winds and seas.

BEACH FORECAST
Issued at 110 PM AST Tue May 5 2026

A moderate risk of rip currents will persist along the northern and eastern beaches of Puerto Rico, as well as in northern areas of Culebra, through Thursday. Across the U.S. Virgin Islands, the risk will be moderate at St. Croix through tonight, then decrease to low through the end of the week for St. Thomas and St. John.

By Friday, conditions are expected to gradually improve in Puerto Rico as well, with a low risk prevailing across most beaches.
Remember that even when the risk is low, life-threatening rip currents can still occur near groins, jetties, reefs, and piers.
By the weekend, breezier winds will bring back a moderate risk across most beaches of the islands. For additional information and location-specific rip current details, visit weather.gov/beach/sju.
