The Lowdown
Alright folks, Rusty here. We’ve got a 16-day outlook for Roca Alta, and it’s a story of a slow build, a solid window of punchy surf, and then a fade. Let’s get into it.
The forecast kicks off with nothing worth paddling out for straight away. Conditions are marginal through Wednesday the 15th and Thursday the 16th, with that ENE swell building but being let down by messy, cross-onshore winds or stormy skies. The wave energy is moderate (469 – 1067), but the quality just isn’t there. You’ll want to wait.
The real standout arrives on Friday the 17th. This is the one to circle. Morning sees a solid 8ft swell from the ENE, with a period of 10 seconds, and the wind swings cross-offshore from the west, leaving the wave face clean. The combined energy jumps to strong (1332), and by the afternoon, the wind drops to glassy. This is excellent surf for experienced surfers, with that reef handling the long-period groundswell nicely. If you’re an advanced paddler, this is your session.
The weekend through Monday the 20th holds decent size, still in the 7ft to 8ft range, but the wind is a bit more fickle. Saturday and Sunday are a mix of onshore and cross-shore breezes, keeping the quality marginal. But Monday morning is a little gem: glassy conditions, 7ft swell, and moderate wave energy (922). It’s not the peak of Friday, but it’ll be very good.
Tuesday the 21st and Wednesday the 22nd see the swell stick around, with the energy hanging in the moderate-to-strong range (827 – 1080). Wednesday afternoon is another highlight with clean, cross-off winds and a solid 8ft swell. Again, this is for the experienced crew.
After that, the swell slowly backs off through the end of July and into the first days of August. There’s a few fun windows, like Saturday the 25th and Sunday the 26th, with clean, glassy conditions and 5ft to 6ft waves. Good for a cruise, but nothing like the punch of that Friday the 17th. The water temp is sitting around 84°F, which is pretty much average for this time of year, so no surprises there.
Crowds at Roca Alta can be a factor sometimes, so for that Friday standout, expect a few other keen surfers in the water. The reef is calling.
Stay stoked.

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.
