The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' over the next couple of weeks.
First off, the water is absolutely roasting. We're talking 87°F, which is a massive 5°F warmer than usual for this time of year. That's a real treat, feels like a bath.
The Rock-Costa Azul is a consistent reef break that's got a bit of a Jekyll and Hyde thing goin' on for the next few days. The start of the week is a write-off. Monday morning has a risk of t-storms, and while there's a clean little 2ft SW groundswell with a nice long 13-second period, the light breeze is from the NW, so it's not quite offshore. The energy is weak. Monday afternoon and Tuesday are just a mess of poor surf, with cross and cross-on winds. Don't even bother.
The first real glimmer of hope comes on Thursday afternoon, the 6th of August. The swell picks up to 2ft from the SSW with a very long 18-second period, and the energy jumps to a moderate level. The wind goes light and cross-off from the WSW. That's a clean window. The swell is small, but that long period will give it some shape on the reef. Expect good surf conditions.
Friday the 7th is a bit of a mixed bag. The morning has a light cross-on breeze, but the afternoon cleans right up. Swell is 3ft from the SSW at 17 seconds, with strong energy. The wind goes cross-off from the WSW. It's gonna be very good, clean fun. This is a solid option for the week.
Saturday the 8th has another clean afternoon on the cards. Swell drops a touch to 3ft from the SSW, but the period is still a solid 15 seconds. The energy is still strong. The wind is light and cross-off from the SW. Expect very good surf conditions.
Sunday the 9th and Monday the 10th are marginal. The swell is still there, but the wind isn't doing us any favours. The energy is still strong, but the quality drops off.
Now, if you're looking for the true standout of the forecast, you've got to be patient. The real magic is on Friday afternoon, the 14th of August. The swell builds to 4ft from the SSW with a 17-second period, and the combined energy hits a massive level. That's a powerful, strong groundswell. The wind is a gentle cross-off from the WSW. This is going to be excellent surf conditions for experienced surfers. This is the one. The swell is over 3ft, so it's getting a bit more serious, and with that long period, the reef is going to handle it beautifully. Expect it to be a bit of a paddle out there, but the waves will be well worth it.
The following weekend is okay, but not as good. Saturday the 15th is marred by onshore winds in the morning, and the afternoon is just marginal. The best of the second week comes on Sunday afternoon, the 16th of August. The swell is 3ft from the SSW, with a 14-second period and strong energy. The wind turns offshore from the W. That's a clean, gentle offshore breeze. Expect very good surf conditions. This one's a promising call, but we're a week out, so keep an eye on it.
So, the pick of the bunch is clear: Friday the 14th afternoon is your best bet for the biggest, most powerful swell. The Rock-Costa Azul is a consistent spot, so it should handle that energy well. If you want something a bit smaller but still clean, Thursday afternoon the 6th and Friday afternoon the 7th are your go-to sessions.
Stay stoked, and I'll see you out there.

Information about the The Rock-Costa Azul Surf forecast
The above surf forecast table for The Rock-Costa Azul provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Rock-Costa Azul can be found by selecting the local surf guide option on the grey menu. Our The Rock-Costa Azul 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 (The Rock-Costa Azul) 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 The Rock-Costa Azul 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.
