Table - best surf conditions forecast for Roca Alta over the next 16 days.
G’day, Rusty here. Let’s break down what Roca Alta’s got in store for the next 16 days.
This is a reef break for the advanced crew, and it’s fairly consistent. The main swell is coming from the ENE, but the quality’s a mixed bag. Water temp is 84°F, which is pretty average for this time of year, so nothing wild there.
The first real standout is Friday, July 17th. The morning is dead glassy, with a 8ft swell from the ENE. The period is 11 seconds – a nice groundswell – and the combined energy is strong at 1313. This is excellent surf for experienced surfers, but at over 8ft, it’s strictly for the experts. Expect crowds, too, as it can get busy.
A lot of the other days are a bit messy with cross-shore winds and marginal conditions. The swell hangs around 6ft to 8ft most of the time. But there’s another bright spot on Tuesday, July 21st. The morning is glassy again with a 7ft ENE swell, period still 10 seconds, and energy at 908 (strong). The forecast says “expect very good surf conditions,” so that’s a solid session.
Later on, Saturday, July 25th afternoon looks clean and glassy with a 6ft swell from the ENE. Energy is moderate at 643, but it’s a nice clean option. The same morning has a clean, cross-offshore breeze with a 6ft swell and 725 energy, so that’s a good day for a double dip.
The rest of the window is mostly average – cross-shore breezes, some onshore winds, and a lot of “marginal” calls. This reef handles the long-period swell better than a beach break, but the wind is the real issue. There’s a big gap of average stuff from the 18th to the 20th, and again from the 22nd to the 24th. For a fairly consistent spot, it’s a bit of a waiting game, but things can always turn.
Mark Friday the 17th morning and Tuesday the 21st morning as the ones to chase.
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.
