The Lowdown
Alright, Rusty here. Let’s break this down for the imperial heads.
First thing to know: this is a tough run of surf. The only break we’re looking at is Roca Alta, a reef that needs a northeast swell. It’s a spot for experienced surfers only, and it breaks fairly consistently. Water temp is around 84°, which is totally normal for this time of year.
From Sunday the 23rd through most of the week, it’s all small and choppy. Swell is 4 to 5 feet, but the period is short—8 to 9 seconds—and the wind is mostly cross or cross-onshore. You’ll find bumpy, weak waves with energy in the moderate range, around 224 to 370. Don’t bother until things change.
The big turn happens on Friday the 28th afternoon. Swell jumps to 7 feet from ENE with a 9-second period, and the wind goes light cross-offshore from the west. That’s clean, lined-up surf with good energy at 646. This is the best session in the whole 16 days. It’s an advanced wave at this size, but if you’ve got the skill, it’ll be firing.
Saturday the 29th morning is also a good call. Swell drops to 5 feet, but the wind goes glassy from the northwest at 3 mph. That’s butter. Energy sits at 385. Crowds are possible—this spot can get some company, so paddle out early.
Everything after that drops off hard. Late August and early September are small—3 to 4 feet—with short period and onshore wind. There are a few glassy mornings, like Saturday the 5th and Sunday the 6th, but the swell is weak, energy in the 150s to 280s. These are distant possibilities, more than a week out, so don’t book your trip yet.
The only real standout is Friday the 28th afternoon. Don’t sleep on it.
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.
