Alright, let’s take a look at what’s shaping up for Roca Alta over the next couple of weeks.
Alright mate, Rusty here. Right now, the surf is a bit of a mixed bag at Roca Alta. There’s some solid swell energy pushing through – we’re talking moderate wave energy bouncing around the 800 to 900 mark (794) – but the wind and general conditions are keeping things from really firing. The swell’s coming from the ENE, around 7ft, with a 10-second period, which is a decent, workable swell. The wind’s blowing cross-on or onshore most of the time, which is turning the ocean into a bit of a mess. Roca Alta is a reef break, demanding advanced skills, so you really need clean conditions. It’s not looking great for the first few days.
Thursday the 9th and Friday the 10th are pretty much write-offs. The wind is rubbish, the sky is threatening storms, and the surf is just marginal. Not worth paddling out for.
Now, Saturday the 11th is our first real standout. The morning starts with a glassy calm, mate. Zero wind. It doesn’t get any better than that for a wave. The swell is a solid 7ft from the ENE, and the energy jumps up to 890. It’s a bit of a gamble because the forecast says “moderate rain,” but if you can handle a little drizzle, the surf itself is looking very good. The afternoon cleans up even more with a light offshore wind from the SSW, and the swell bumps up to 7ft with 1071 energy. This is the window. The crowd situation here is “sometimes,” so you might have a few others out, but it’s a big enough wave to make it worth it. The water temperature is about average for July, so no need for a thick wetsuit.
Sunday the 12th still has a 8ft swell, which is getting a bit chunky, but the wind goes cross-shore and the energy is even higher at 1363. It’s a lot of water moving around, but the conditions are described as “marginal” due to tides, so it might be a bit of a puzzle to get the right bank.
After that, it gets a bit messy again from Monday the 13th through the middle of the week. The swell drops off a little, and the wind is back to being cross-on or onshore. There’s a brief window on Wednesday the 15th and Thursday the 16th where the wind goes cross-offshore and the surf is clean, but the swell size drops to 5ft – 6ft. It’s a good option for a more relaxed session, but not the big stuff of the weekend.
The second week, from the 17th to the 24th, is really inconsistent. There are a few mornings with glassy conditions, like Monday the 20th and Tuesday the 21st, but the swell is small (5ft – 5ft) and the energy is low. A couple of days, like Wednesday the 22nd, have a glassy start with a 5ft swell, but it’s not going to get the heart racing. The wind is a problem most afternoons, with onshore or cross-on breezes messing up the surface.
Honestly, for the whole 16 days, the best call is Saturday the 11th. Get out there in the morning for the glassy conditions and that 7ft ENE swell, or wait for the afternoon offshore wind. That’s the one to circle on the calendar. Sunday the 12th is a close second if you’re after a bigger wave, but you’ll need to work the tides.
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.
