The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Roca Alta over the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. The first real chance to get wet doesn’t come until Wednesday morning, the 22nd of July. Before that, Tuesday afternoon is a write-off – cross-on wind and marginal conditions. Wednesday morning is where it kicks off with a clean 6 ft swell from the ENE, period at 8 seconds, and a light cross-offshore breeze. The ocean’s got some energy behind it (374), and it’s looking like a solid session. The water temp is sitting at 84°F, which is about normal for this time of year, so no wetsuit needed.
The standout window for the near term is Saturday morning, the 25th of July. We’re looking at a glassy surface with that easterly breeze dropping to almost nothing. The swell holds at 5 ft from the NE, period 9 seconds, and the energy is a solid 316. This is the kind of morning where you paddle out and the only thing you hear is the water. The wind is dead calm, and the waves will be clean. Roca Alta is a reef break for advanced surfers, and it’s fairly consistent, so you can expect waves. Just keep in mind, crowds are possible here, so get out early.
Moving into the next week, there’s a bit of a lull. Wednesday and Thursday the 29th and 30th are pretty weak, with swell dropping to 3 ft and energy barely scraping 101. Not much to write home about. But then we start seeing a build-up towards the end of July and into August.
Now, the real gem in the long-range forecast is Wednesday afternoon, the 5th of August. This one is a bit far out, so take it with a grain of salt, but it’s looking promising. The swell is 6 ft from the ENE, period 9 seconds, and the energy is pumping at 519. The wind is dead flat – glassy conditions. The forecast is calling for very good surf conditions. That’s the one to circle on the calendar. It’s a reef break, so that 9 second period from the ENE will wrap in nicely. The only downside? It’s a long way off, so we’ll have to see how it shapes up.
In between, there are a few morning windows with clean conditions, like Monday the 27th of July with glassy 5 ft swell, and Sunday the 2nd of August with glassy 5 ft, but the energy is a bit lower. The 5th of August is the standout.
If you’re a beginner, keep an eye on the size. The swell tops out around 6 ft later in the period, which is getting into the more advanced territory, especially on a reef. For the rest of us, the 25th of July and the 5th of August are the days to aim for.
Stay salty,
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.
