The Lowdown

Alright, let’s be straight with you. The next couple of weeks are looking pretty gutless for most of the region. We’ve got a long stretch of tiny, weak surf and a lot of wind to deal with. The first real chance of anything worthwhile doesn’t even show up until the 13th, and even that’s a small blip. The run from now until then is a write-off, with only ankle-biters and blown-out lumps on offer. It’s the kind of spell where you’re better off doing a maintenance session on your board or sorting out your fin setup. The energy in the water is minimal, with the combined swell energy mostly sitting in the low single digits, like 2 or 3, which is as weak as it gets.

The first few days are just a tease. On the 4th, there’s a stormy vibe with a moderate offshore breeze, but no swell to speak of. The 5th and 6th bring tiny, short-period slop from the north and south, but it’s under 0.7ft and just not worth paddling out for. The conditions are clean, sure, but you can’t ride what isn’t there. This pattern of nothing continues through the 7th, 8th, and 9th, with the wind picking up out of the east-northeast, making things a bit blustery. The 9th afternoon has a fresh offshore breeze, but only a 0.3ft blip of swell. It’s all show, no go.

The middle of the week, the 10th, 11th, and 12th, remains desperate. We’re stuck with 0.3ft to 0.7ft of short-period south swell, and the energy is still in the low single digits. The wind is mostly offshore, keeping the surface clean, but the lack of any real push means it’s still not worth suiting up. The water temp at the first spot we’re looking at, Crash Boat, is sitting at 84°, which is about 1° warmer than the long-term average. So it’s a bit balmy, but that’s about the only thing that’s notable.

Now, here’s where things get a little more interesting. On the 13th, there’s a slight change. The morning is still poor, but the afternoon shows a new swell from the north with a period of 12 seconds. It’s still tiny at 0.3ft, but that longer period is a hint of something better to come. The energy reading bumps up to 6, which is still weak, but it’s the most we’ve seen. The wind is a fresh offshore, so it’ll be clean. Keep an eye on this.

The 14th and 15th are when the swell finally starts to show a pulse. The 14th afternoon has the wind cranking from the east-northeast at 28 mph, which is strong, but it’s cross-offshore. The swell is only 0.7ft from the south, but the energy is building, hitting 9 and then 10 on the 15th afternoon. This is the most push we’ve seen all week. It’s still small, but it’s a start. The 16th morning looks like the pick of the whole run. We get a 0.7ft south swell with a 10-second period and the energy finally breaks into double digits at 11. The wind is a gentle offshore breeze from the east-northeast, so it should be glassy. It’s not going to be big, but it might be the cleanest, most rideable wave of the entire window.

After that, the 17th and 18th see things fade back out. The swell drops off, the energy sinks back to the low single digits, and we’re back to square one. The 19th shows a little blip again, but nothing to get excited about.

So, what’s the honest call here? There’s really no standout day in this forecast. The best on offer is that Saturday morning on the 16th at Crash Boat. It’s a beach and reef setup that’s usually sheltered, but it’s also inconsistent, so you’ll be waiting for waves. The swell direction is from the south, which might not be the optimum west for this spot, but the clean conditions and the slightly longer period make it the least-bad option. The waves will be small, maybe ankle to knee-high, so it’s still a groveler’s session. Then the 14th and 15th afternoons have a bit more energy, but the strong wind might make it messy and more of a windsurfing or kite session than a pure paddle. With that much wind and a small, weak swell on a beach setup, it’ll likely be blown out and bumpy.

Honestly, for the next two weeks, you’re chasing shadows. The near-term is a washout, and the long-range promise for the 16th is just a glimpse of what could be. Forecasts can change, though, and with the water this warm, it doesn’t stay flat forever. Keep your board waxed and stay ready.

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.
