The Lowdown
Right now, Crash Boat (Puerto Rico) is looking pretty quiet. The water is sitting at 85°, which is about normal for this time of year, so nothing weird there. But honestly, the surf is the story, and it’s a flat one.
We’re staring at a real dry spell for the next couple of weeks. From Tuesday the 15th through to the end of the month, there’s just nothing on the table. The swell energy is tiny – mostly single digits, sometimes down to just 1 or 2, with a few weak pulses up to 40 mid-week. But even that little bump is only showing 2ft at best, and it’s short-period, sloppy stuff. The winds are mostly cross-off or light, so the surface will be clean enough, but you’re chasing nothing. The combined energy stays weak throughout, often under 20, and most days it’s just a dribble. You’d be better off staying home.
There’s a little moment on the afternoon of Friday the 18th and Saturday the 19th morning where the wind turns properly offshore and the swell bumps up to 2ft from the north with a 9-second period. Still small, but at least it’s not completely dead. Then again, the energy is only around 32-40, so it’s marginal. And the 20th has a glassy morning with 1ft from the north – that’s about as good as it gets, and even then, you’re looking at ankle-biters.
The rest of the window is pretty much a write-off. A few tiny pulses of south swell late in the month, but with periods of 4-5 seconds, that’s pure chop. No push, no power. The 23rd has a moderate rain day with barely any swell, and the 27th is completely flat with zero energy. Honestly, if you’re a beginner, this is fine because there’s nothing over 5ft. But for anyone else, there’s just nothing to surf.
The one thing I’ll say: Crash Boat is inconsistent and sheltered, so this kind of flat run isn’t unusual. But it won’t stay like this forever – forecasts change, and when the north or west swells line up with that offshore wind, it’ll be on. Until then, it’s a no-go.

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.
