The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Coronation Beach. It’s a beach and reef setup, fully exposed to the swell, and it likes a good SW pulse. The water is sitting at 67°, which is about normal for this time of year, so nothing weird going on there.
We’ve got a solid run of surf lined up, but it’s a bit of a mixed bag with the wind. The first real standout is Friday morning, August 21st. We’ve got a clean 8ft SW groundswell, with a long, juicy 15-second period, and the wind is blowing offshore from the ESE at 9 mph. The water will be glassy, the lines will be clean, and the wave energy is sitting at a solid 2482. This is your pick of the first week—for experienced surfers who can handle that size, it’s going to be magic.
The swell hangs around but the wind gets a bit messy through the weekend. By Monday morning, August 24th, it cleans up again. Another 7ft SW swell with a 15-second period, and this time the wind is a gentle cross-offshore from the south at 9 mph. The energy is moderate at 1889, and conditions are looking excellent again. That’s your second best bet for the first week.
Now, we hit a bit of a lull mid-week, but the end of the forecast period is seriously promising. On Sunday, August 30th, the morning looks absolutely incredible. There’s a 4ft SW groundswell, but the period is a massive 20 seconds—that’s very long-period energy, perfect for a reef like this. The wind is glassy, completely calm from the NNW at just 3 mph. The combined energy is still a strong 2398, so don’t let the smaller height fool you; there’s plenty of push. That’s a standout morning for sure.
Then, to cap it all off, Monday morning, August 31st, delivers a proper 8ft SW swell with a 17-second period, offshore wind from the ESE at 6 mph, and a massive energy reading of 3298. The forecast gives it top marks for experienced surfers. That’s as good as it gets in this 16-day window.
There are a few days with onshore or strong cross-winds, and some of the bigger swells (over 8ft) are only for the experts. The 10ft to 12ft days around the 26th and 27th look all wind-affected and messy, so I’d skip those. But overall, Coronation is looking like a consistent performer with a couple of absolute gems.
Rusty, signing off.

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.
