The Lowdown
Alright, Rusty here. Let’s talk about what’s cookin’ for the next couple weeks in feet and miles per hour.
Honestly, it’s a grim outlook at first. We’ve got a long lull with no surf on offer from the start up through the 7th of September. The first real chance of a wave doesn’t come until the 8th. Before that, it’s all tiny bumps, glassy mornings, and nothing worth paddling for.
Tuesday the 8th is the first real sign of life. Crash Boat (Puerto Rico) – the only break in the picture here – sees a tiny south swell, only 1ft with a short 6-second period. The combined energy is weak (11). The morning has a light cross-off breeze from the ENE at 6 mph, keeping the surface clean. It’s not much, but it’s a start.
Wednesday the 9th is a little better. The morning brings an offshore wind from the ENE at 9 mph, paired with a 0.7ft north swell that has a much longer 11-second period. Combined energy is 14. That offshore wind will clean up the little waves nicely. By the afternoon, the swell builds to 1ft from the north, 10-second period, with energy jumping to 39, but the wind goes cross-off at 16 mph, so it’ll be a bit bumpy.
Thursday the 10th is the one clear standout of the entire 16-day run. We get a 2ft north swell, 10-second period, and combined energy of 72 – moderate for this spot. The morning’s cross-off wind from the east at 9 mph keeps it rideable. It’s the best wave we’ll see. The water is warm at 86°, a little above average for early September, so you’ll be in boardies.
After the 10th, it fades fast. Friday the 11th has a brief pulse of 2ft from the SSE with a clean offshore wind on Friday afternoon, but the energy drops to 14. From the 12th onward, it’s mostly flat and glassy. By the 17th, there’s hardly a ripple.
The standout? Thursday the 10th of September. Crash Boat in the morning with that 2ft north swell, 10-second period, and light cross-off wind is the only real window of the fortnight. It’s not big, not exciting, but it’s the best on offer. Just know that when there’s a wave, Crash Boat can pack out.
Hang tight – these dry spells never last forever.

Information about the Crash Boat Surf forecast
The above surf forecast table for Crash Boat provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Crash Boat can be found by selecting the local surf guide option on the grey menu. Our Crash Boat surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Crash Boat) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Crash Boat may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Crash Boat is 4 km (2 miles) from the city of Aguadilla. If you plan a holiday in Puerto Rico, look for hotels and other accommodation in Aguadilla. Aguadilla has rooms for a wide range of budgets as well as car hire and transport links.
