Alright, Rusty here again. Let’s break down what’s happening at Roca Alta. This is a reef break, and it’s an expert-only spot, so don’t even think about it if you’re not confident. It breaks fairly consistently, and the swell is coming from the ENE – that lines up with what this place likes best. The water’s around 84°, which is normal for this time of year, nothing unusual.
First up, Monday, 6th July is a dud. Stormy weather, messy cross-onshore wind, and the swell is weak. The energy is low (213). Don’t bother paddling out.
Tuesday, 7th July morning is where it starts. We’ve got a 1.8m swell from the ENE, a 9-second period, and the wind is glassy. Clean conditions, building energy (547). That’s a good session, and the morning is the window. Afternoon goes onshore, so you’ll want to be out early.
Wednesday and Thursday are just okay. Swell builds to 2.1m on Thursday, but the wind is cross-on, so the surface won’t be perfect. Still surfable, just nothing to write home about.
But then we hit the big one. Saturday, 11th July. Swell hits 2.3m, period stretches to 11 seconds, and the wind is glassy. The energy is cranking at 1291. Sunday, 12th July morning is even bigger – 2.5m, glassy, and energy at 1490. That’s legit big for a reef, only for experts. Long period at 11 seconds means the waves will have plenty of power and shape, but there will be longer waits between sets. Expect the crowd to be heavy on those days. Saturday morning and Sunday morning are the absolute best of the whole run.
Monday, 13th July afternoon turns glassy again with a solid 2.1m swell (energy 831). That’s another great session if you missed the weekend.
After that, the second week drops off. Swell stays around 1.7m to 2.0m, but the wind is mostly cross or cross-on. Nothing special. Some morning sessions on 15th and 21st July are okay, but not worth getting excited about.
So, in plain English: skip the start of the week. Tuesday morning is good. The real deal is Saturday and Sunday, 11th and 12th of July. Get after it.

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.
