The Lowdown

G’day, Rusty here. Let’s break down what’s happening at The Rock-Costa Azul. Got a good stretch of waves comin’ but you gotta play the wind and size right.

First off, the water’s warm – 88°, which is a solid 5° above normal for this time of year. Feels like a steamy bath.

Starts on Monday afternoon, 31 August. Glassy conditions, 0.8m swell from the SSW, 13-second period. Moderate energy (431). Dead calm wind, clean little waves on the reef. That’s a beauty for experienced surfers.

Tuesday morning, 1 September, swell holds at 0.9m from the SSW but wind goes cross-on at 10 km/h. Small ripples, poor conditions. Afternoon drops to 0.6m with a 20 km/h cross-shore. No good.

Wednesday, 2 September, swell jumps to 2.5m in the morning from the SSE, 11-second period, onshore wind. Strong energy (1977). Then afternoon hits 3.0m from the S, 12 seconds, 2751 energy. It’s too big for this break and rough – better for kites than paddles.

Thursday, 3 September, swell stays 2-2.5m, periods around 10-12 seconds. Morning’s onshore, afternoon cross-shore at 15 km/h. Still big and bumpy.

Friday, 4 September, similar – 2-2.4m, 11-second period, onshore mornings and cross-chop afternoons.

Saturday, 5 September morning – this is your top pick. Swell drops to 1.4m from the SSW, very long 16-second period. Cross-offshore wind (15 km/h). Strong energy (1342) and the data says it’s excellent for experienced surfers. Clean and powerful. Afternoon stays clean at 1.3m.

Sunday, 6 September morning – another standout. Glassy, 1.2m from the SSW, 15-second period, light air. Clean as a whistle. Afternoon has offshore wind at 20 km/h, still clean at 1.2m.

Monday, 7 September – zero wind, glassy, 1.0m from the SSW, 14 seconds. Perfect conditions. Afternoon stays offshore and clean.

Tuesday, 8 September onward, the swell drops to 0.8-1.0m but wind turns onshore or cross-onshore 20-25 km/h. Poor or marginal conditions through to the end.

Friday, 11 September morning, we get a clean window – 1.0m from the SW, 15 seconds, cross-offshore breeze (15 km/h). Clean.

Saturday, 12 September morning: glassy, 0.9m SW. Sunday, 13 September morning: glassy, 0.7m SW. Small but clean for a quiet paddle.

After Monday, 14 September, swell drops to 0.5-0.7m with onshore winds. Not worth it.

The best days: Saturday 5 September morning and Sunday 6 September morning – solid, clean, long-period groundswell with offshore/glass conditions. For the second week, the glassy mornings on 12 and 13 September are your small but clean option. Crowds are listed as “often,” so expect company.

Rusty out.

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.
