The Lowdown

Alright, folks, Rusty here. Let's get into it. The long-range models are showing a bit of a tease for Roca Alta, but honestly, the next week and a half looks pretty grim for getting wet. We've got a lot of small, weak surf and less-than-ideal winds. You're gonna have to be patient. There's a window late in the run that has some potential, but we're not talking about a classic by any stretch.

Here’s the rundown. The water temp at Roca Alta is sitting right around 84°F, which is about average for this time of year, so you won't need the thick rubber. For the next few days, through the 29th, the surf stays small, around 5ft to 6ft, but it's mostly cross-onshore with ripples and the energy is weak, with combined swell energy between 354 and 547. It’s choppy and messy, not worth your time unless you're desperate.

There's a brief flash on Friday morning, the 28th. The swell bumps up slightly to 7ft from the ENE with a period of 10 seconds, and the wind goes glassy. That'll clean it up and it's about as good as it gets in this stretch, with energy hitting 815. Still, it's only 7ft, so it's not huge, but it's rideable and probably the pick of the first week. Don't expect any crowds to be a problem; this spot is fairly consistent, but with conditions like this, most people will be doing something else.

After that, it fades again. From the 30th through the 4th, we're looking at surf dropping from 5ft down to a dribble of 1ft. The energy drops right off, with readings from 331 down to 56. It’s a real flat spell, and with the winds mostly cross or onshore, it's a total write-off. You'd be better off finding a pool.

Then there’s a small pulse around the 5th and 6th, but the swell is short-period and the winds are all over the place. Not worth paddling out for.

Now, the interesting bit. Looking way out, around the 10th of September, we see a push of new energy. The swell height climbs back up to 4ft from the ENE with a period of 9 seconds, but the real story is the wind. On the morning of the 10th, the forecast shows a WNW wind at 9 mph, which is cross-shore, and the energy reading is 280. It's not huge, but it's more than we've seen. The afternoon turns messy again, but that morning window on Thursday the 10th could be your best bet. It’s a week and a half away, so treat it as promising but not locked in.

Overall, if you’re keen, that Friday morning on the 28th and the morning of the 10th are your windows. Everything else, you're just fighting the chop. Keep an eye on it, but don't hold your breath.

Rusty out.

Information about the Roca Alta Surf forecast

The above surf forecast table for Roca Alta provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Roca Alta can be found by selecting the local surf guide option on the grey menu. Our Roca Alta 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 (Roca Alta) 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 Roca Alta 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.
