The Lowdown
G’day, I’m Rusty, and I’ve been staring at charts for this stretch of coast all morning. Let’s get into it.
The first real action kicks off Saturday the 15th of August, with a solid SW groundswell rolling in. It’s a strong, energetic pulse (combined energy 1290). Saturday morning is the standout early call: Coronation Beach is a beach and reef setup, and it’s got a clean 6 ft SW swell with a 14-second period, powered by a glassy NE cross-off breeze at just 3 mph. The water’s sitting at 67°, about normal for this time of year. This is proper, clean surf for experienced surfers—not for beginners though, as it’s over 5 ft. The wind is almost perfect, so the faces will be smooth. It could get a little crowded because it’s exposed and consistent, but worth it.
Saturday afternoon, the wind shifts to a southerly 9 mph cross-shore, and the swell drops a touch to 6 ft. It’s a bit lumpy, but still surfable for the keen.
Sunday the 16th, the morning is tiny—only 3 ft—with a strong 19 mph cross-off NE wind, so it’s clean but small. The real highlight is Sunday afternoon: the swell picks up to 6 ft SW, the period stretches to 16 seconds, and the wind turns offshore from the ENE at 6 mph. That’s clean, long-period groundswell, and the combined energy jumps to 1537. This is another excellent session for the experienced crew.
Monday the 17th is a write-off. Onshore winds and rain ruin the morning, and by the afternoon it’s a messy 8 ft SW with cross-onshore wind at 19 mph. Wave energy is high (3770), but the quality is poor.
Tuesday the 18th is the absolute pinnacle of the whole outlook. Tuesday morning: 10 ft of SW groundswell, 17-second period, combined energy of 5214—that’s pumping. And the wind? A light 3 mph offshore from the east. This is exceptional surf, but it’s strictly for experts only—over 8 ft is a heavy day. If you’re not confident paddling into big, clean walls, give it a miss. The afternoon holds similar size but the wind goes cross-shore, making it a bit tricky.
Wednesday the 19th and Thursday the 20th keep the swell solid, between 7 ft and 8 ft SW, with 15-16 second periods. Morning sessions are the go, with clean cross-off winds. By Thursday morning, the combined energy is 3710, and the wind is light cross-off from the SSE. That’s a top-tier session for experienced surfers.
Friday the 21st, morning is a cracker: 7 ft SW with a moderate offshore breeze from the ESE at 16 mph. The energy is 1784, and it’s clean. The afternoon stays good but with a cross-off wind.
Moving into the second week, things get more variable. Saturday the 22nd and Sunday the 23rd have smaller, cleaner swell, around 4 ft to 7 ft, with cross-off winds. Marginal but surfable.
Monday the 24th and Tuesday the 25th are a write-off again—strong onshore winds and messy, big swell. Tuesday the 25th has 10 ft SW but with a 28 mph cross-on gale. Not worth it.
Then Wednesday the 26th of August brings a big pulse: 12 ft SW groundswell, 16-second period, combined energy of 5418. The wind is cross-off from the SE at 12 mph, so it’s clean. But that size is massive, only for experts. The afternoon holds 10 ft.
Thursday the 27th offers a nice, clean 7 ft SW morning with offshore ENE wind—excellent for experienced surfers. The energy is 1968.
Friday the 28th is back to small, clean 4 ft with a cross-off, but the afternoon turns ugly with a cross-on wind.
The last weekend, Saturday the 29th and Sunday the 30th, is messy with onshore winds and rain, and swell around 7 ft to 8 ft. Not recommended.
The two true standouts are Tuesday morning the 18th of August and Wednesday morning the 26th of August. The 18th is the best of the whole window: big, clean, and offshore. The 26th has bigger swell but is also clean—both are for experts only.
If you’re a beginner, aim for Saturday the 15th or Sunday the 16th early, but even then it’s over 5 ft. This is a stretch that delivers consistent, powerful groundswell, but you need to pick your windows.
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.
