The Lowdown

G’day, Rusty here.

Alright, let’s have a look at what’s coming down the pipe for The Rock-Costa Azul. This is a reef setup, so it handles a bit of power, and it’s consistent – that’s a good start. The water’s sitting at 87° right now, which is 5° warmer than what you’d normally get at this time of year, so it’s a fair bit toastier than usual.

We’re starting off on Monday, the 10th of August. The afternoon is looking sweet – a 2ft swell from the SSW with a long period of 19 seconds, and a light cross-offshore breeze from the SW at 9 mph. The wave energy is moderate (548), and it’s going to be clean. That long period will really make those lines stand up nicely on the reef.

Tuesday the 11th is a bit of a downer. The morning’s junk with tricky tides, and the afternoon’s only marginal with a 2ft swell. Not the day to pull the trigger.

Wednesday the 12th has some potential, but you gotta pick the window. The morning has a cross-shore breeze, not ideal. But check out the afternoon – it goes glassy with a 3ft swell from the SW, a 16-second period, and light northwesterly wind at just 3 mph. Expect good surf conditions. The combined energy is moderate (469), and that flat wind is going to make it look like velvet.

Thursday the 13th: the morning is a cross-onshore mess, but the afternoon fires up. A 3ft SW swell, 15-second period, and a clean offshore wind from the west at 6 mph. The energy jumps to moderate (698) and it’ll be very good. That’s a solid session.

Now, Friday the 14th – this is the standout of the whole forecast. The afternoon brings a 5ft swell from the SW, a 17-second period, and clean cross-offshore winds at 6 mph. The energy hits strong at 1214. This is excellent, experienced surfer territory. For the advanced crew, this is the one to circle. The size is just right for the reef, and that long period will be pushing a lot of water.

Saturday the 15th is still very good. The afternoon has a 4ft SSW swell, 16-second period, with gentle cross-offshore breeze. Clean and punchy with moderate energy (874).

Sunday the 16th: a bit smaller at 4ft, but the afternoon goes glassy again with a 14-second period from the SW. Clean and nice, moderate energy (532). A good end to the week.

After that, from the 17th through to the 21st of August, the swell drops off a bit, staying between 3ft and 4ft. There are windows of clean surf, especially on Monday the 17th afternoon (4ft SW, 16s, clean) and Thursday the 20th afternoon (3ft SSW, 13s, moderate offshore). But nothing that really jumps out as a must-surf. The 22nd and 23rd are flat-ish and marginal, with a small uptick on Sunday the 23rd afternoon (2ft SW, 18s, offshore).

We wrap up on Monday the 24th with a glassy morning and a 2ft SW swell at 16 seconds. Then Tuesday the 25th is a write-off.

So the absolute best on offer: Thursday the 13th afternoon for that sweet offshore, and Friday the 14th afternoon for the biggest, cleanest swell of the run. The long-period swells here at the reef will be lining up nicely, but they will have longer lulls between sets, so take your time paddling out.

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.
