The Lowdown
Alright, let's talk surf for Roca Alta. It’s a bit of a slow grind ahead, with the swell coming from the east-northeast, which is mostly side-on this spot. We’ve got a mix of cross and cross-onshore winds, so it’s going to be a little bumpy for most of the time.
The first day or so is pretty average. Monday the 14th has some chest-high waves at 6 feet, but the period is only 10 seconds and the cross-shore wind will chop it up. The water is a warm 84°, which is about 1° warmer than average for this time of year—nothing special, just a bit more tropical. The wave energy is moderate, at 622, but the conditions are only borderline.
Tuesday drops a touch to 5 feet, with a light cross breeze. It’s not terrible, but it’s nothing to get excited about. Wednesday is the real highlight of the first week. The wind goes dead glassy, which is a game-changer. The swell is down to 5 feet, but it’s clean and has a bit of push behind it. This is the day to get wet if you want the best chance at a clean wave. It’s still not pumping, with moderate energy at 286, but it will be your best bet for a smooth, glassy session.
After Wednesday, the quality fades. The swell hangs around 4 to 5 feet, but the cross-onshore wind makes conditions pretty poor. There are a few windows of light wind, but the waves are weak and short-period. We're looking at a dry spell from Thursday the 17th through almost a week.
We see some glassy conditions again around the 22nd, but the swell has dropped to 3 feet. It’s rideable, but you’d need a longboard and a lot of patience. The energy is weak, down in the 70s. There is a slight bump around the 24th and 25th with some clean mornings and the swell getting back to just over 3 feet, but it’s still not great. Light winds are a plus, but the waves will be small and weak.
Looking further out to the end of September and into October, it’s more of the same. There are periods of clean, glassy conditions, but the swell stays small, bouncing between 2 feet and 3 feet. It’s not flat, but it’s a quiet time for the spot. There’s one small kick on Monday the 28th with a cross-offshore wind, but the swell is still only 3 feet. It’s going to take some patience to find a decent wave in the next couple of weeks.

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.
