The Lowdown
Alright folks, Rusty here. Let’s break down what’s on offer for Coronation Beach.
We’ve got a solid run of SW groundswell coming through, and the real standout is Thursday morning, the 20th of August. We’re talking a clean 8 ft SW swell, with a 16-second period, and a light cross-off breeze from the ESE at 9 mph. The combined energy is pumping at 3710 (moderate to strong energy), and the water temp is 67°, which is about average for this time of year. This is the one to aim for – powerful, clean, and for experienced surfers only.
Before that, Wednesday morning the 19th is also solid: 8 ft SW, 15-second period, with a cross-off wind from the SE at 6 mph. Combined energy is 2465 (moderate energy). Crowds are possible, so keep an eye out.
Friday morning the 21st is another cracker: 8 ft SW, 15-second period, and true offshore wind from the E at 9 mph. Combined energy 2547 (moderate energy). That’s a morning of clean, peeling lines.
The swell drops off over the weekend, with Sunday the 23rd looking small and messy at 5 ft with a 14-second period and southerly wind making it choppy.
Monday the 24th morning picks up a little: 6 ft SW, 14-second period, and light cross-off wind from the SE. Combined energy 1443. It’s clean, but not the standout.
Tuesday morning the 25th is a sneaky good one. The swell is only 4 ft, period at 12 seconds, but the wind is glassy – 3 mph from the SW. Combined energy is a low 528, but for a small-wave board, it’ll be silky smooth.
From the 26th, the swell gets big again. Wednesday the 26th morning is 8 ft SW, 17-second period, but cross-shore wind makes it a bit messy. By the afternoon, it’s a solid 10 ft, but with a cross-onshore wind, it’s going to be lumpy. Expert-only.
The end of August is a mixed bag. The 31st has strong WNW winds at 18-25 mph with 7 ft to 8 ft swell – that’s more for kite-surfing than a clean paddle.
Into September, Tuesday the 1st morning looks promising: 8 ft WSW, 16-second period, with a cross-off wind from the SSE at 12 mph. Combined energy 3374 (strong energy). That’s a big, clean groundswell for experienced surfers. Wednesday the 2nd morning is also a beauty: 6 ft SW, 14-second period, and true offshore wind from the ENE at 9 mph. Combined energy 1307. Clean and fun.
After that, the swell fades into the 3rd of September with 5 ft to 5 ft and period dropping to 13 seconds, with cross-shore winds. Nothing special.
The absolute standout is Thursday morning, the 20th of August. Big, clean, and powerful. Honourable mention to Friday the 21st and Tuesday morning the 25th for the glassy conditions.
Catch you out there.
Rusty.

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