The Lowdown
G’day, Rusty here. Look, it’s a bit of a slow start for The Rock-Costa Azul, a reef setup that loves a solid S swell. The water’s sitting at 86°F, which is much warmer than usual for this time of year, so you’ll be in boardshorts from the get-go.
The first few days are pretty ordinary. Friday the 31st kicks off with a weak 3ft SSW swell at 13 seconds, but with a cross-on breeze it’s messy and blown out - the combined energy is only 388 (weak to moderate), so not much to get excited about. Saturday morning, August 1st, cleans up a bit with a light cross-off wind and a 3ft SSW swell, but it’s still small (energy 355). Sunday arvo, the 2nd, has a decent offshore breeze from the WNW at 16 mph, but the swell drops to 2ft - it’s clean but tiny. The rest of the first week is a grind: small waves, often cross-shore or onshore winds, and mostly poor to marginal conditions. The combined energy hovers between 128 and 388, telling you it’s weak.
Then we get a whisper of something better. From Thursday the 6th, the swell starts to fill in with a longer period - 18 seconds on Thursday arvo, pushing 2ft from the SSW with an energy of 500, though it’s still a bit raw with that cross-off. By Friday the 7th morning, you’ve got 3ft SSW at 17 seconds, energy 650, but it’s cross-on. The real standout is way out there, two weeks ahead: Friday the 14th of August. That morning, the swell jumps to 5ft from the SW, period 18 seconds, with glassy conditions - the energy is a solid 1233 (strong). It’s labelled excellent for experienced surfers, so that’s your best bet. Saturday the 15th arvo holds 5ft SW at 16 seconds, clean and cross-off, with energy 1016 - also excellent. The long period (18-20 seconds) means this is a proper groundswell, gold at this reef.
But here’s the thing: this is an advanced break, and when the swell gets over 5ft, as it does on Friday arvo the 14th (5ft), it’s expert-only territory. The long period will also make it a bit straight at times, but for a reef, that’s energy you can work with. Crowds are often a factor here, so expect company. The first two weeks are a write-off for anything decent, but that second-week window from August 11th onward shows promise, especially the 14th and 15th - that’s the one to circle on the calendar. Off the wind, it’s all about that SW swell direction, which matches the optimum swell from the south.
So, heads up: the next 10 days are mostly flat or weak. After that, it gets interesting. I’ll be watching the 14th closely.
Rusty.

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.
