The Lowdown
Alright, this is Rusty. Let's break down what's coming up for this spot.
It’s a slow burner. The first few days are pretty flat and choppy, nothing worth paddling out for. The story really starts to pick up toward the end of the first week, and then the second week is where the real action is.
The best window is between the 12th and the 16th of August. We’re looking at a consistent ENE groundswell with periods of 10 to 11 seconds. The combined energy is strong, starting at 904 on the 12th and peaking at 1554 on the 16th. That’s a lot of power in the water.
The top pick has to be Roca Alta. It’s a reef break, which is perfect for this kind of longer-period swell. The morning of the 13th of August is looking like a standout. You’ve got a 2.3m swell from the ENE, 10-second period, and glassy conditions. The water temp is 29° with a 0.6° anomaly, so it’s about normal for this time of year. The energy is a strong 1110. This is a wave for experienced surfers, and it can get crowded sometimes, so get there early.
Another absolute cracker is the morning of the 16th of August. The swell is at 2.5m from the ENE, the period is 11 seconds, and it’s glassy. The energy is massive at 1554. This is for experts only at that size, but if you’re up for it, the conditions are going to be pristine with the offshore wind.
The pattern is clear: the mornings are the go. The afternoons tend to get a cross-onshore wind that messes up the surface. So, plan for dawn patrols to get the cleanest waves.
Rusty.

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.
