The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer at Roca Alta. This is a proper advanced reef break, and it’s exposed to the swell, so when it’s on, it’s on. The water is sitting at 84°, which is about average for the time of year, so no surprises there.
The outlook kicks off on Monday the 27th of July. We’ve got a clean 4ft swell from the ENE with a 9-second period, and the wind is glassy in the morning. That’s going to produce some good, clean waves for the advanced crew. The combined swell energy is a moderate 267, so there’s some push behind it. It’s a solid start, but the afternoon sees the wind shift onshore, and the quality drops right off.
Tuesday the 28th is a write-off with cross-onshore winds and messy conditions. Wednesday the 29th morning has a glassy start but the swell drops to 3ft with only 106 energy, so it’s surfable but very ordinary. You’re not missing much.
Now, the first real standout hits on Thursday the 30th of July. The morning brings a glassy 5ft swell from the ENE, period bumping up to 9 seconds, and the energy jumps to 324. That’s moderate energy, but with those clean conditions, Roca Alta will be offering some proper lines. This is your best bet for the first week.
Friday the 31st shows a bit more size (6ft) but the wind is cross-onshore, making it choppy. Not worth the drive.
Moving into the weekend, Saturday the 1st of August has a 7ft ENE swell with 10-second period and a cross-shore wind. The energy is high at 940, but with the wind, it’s marginal. By Sunday the 2nd, the swell drops back to 6ft, and the wind stays cross-shore in the morning, but it’s still not ideal.
The second week is a bit of a mixed bag. There’s a long gap of nothing special until Thursday the 6th of August. That morning is a beauty: glassy conditions, 6ft ENE swell, 10-second period, and a combined energy of 566. It’s looking very good, and the crowd situation is only “sometimes” an issue, so you might get it to yourself if you’re early. That’s the standout of the second week, but it’s a week and a half away, so keep an eye on the forecast.
Then we get to Monday the 10th of August. The morning is absolutely dead calm—zero wind, glassy, with a 7ft ENE swell at 10 seconds and 815 energy. That’s a strong, clean swell right on the reef. For the advanced surfer, this is a dream. It’s a promising call, but it’s far out, so don’t lock it in just yet.
Overall, the best windows are Thursday the 30th of July, Thursday the 6th of August, and Monday the 10th of August. Get on those mornings. The rest of the period is mostly average to poor, so pick your moments.
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.
