The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of swell on the way for Coronation Beach, a consistent beach and reef setup that’s exposed to the SW. The water is sitting at about 68°, which is pretty much normal for this time of year, so no surprises there.
The first real action kicks off Monday, August 24th. The morning is the standout early in the window. We’re looking at a clean 7 ft groundswell from the SW with a period of 15 seconds, under a light cross-offshore breeze. The combined energy is pumping at 1760 (moderate), and the conditions are clean. It’s a bit of size, so it’s more for the experienced crew, but the quality will be there. The afternoon stays on the smaller side at 6 ft, but the wind shifts cross-on and roughens it up a bit.
Tuesday, August 25th morning is a gem. The swell drops slightly to 5 ft, but the wind is glassy—absolutely dead calm. That’s a major positive. The swell period is 12 seconds from the SW, and the energy sits at 948 (moderate). It’s a great window for a long session with clean lines.
The big stuff rolls in Wednesday, August 26th. The morning sees a 8 ft SW groundswell with a 16-second period, but the wind is onshore from the WNW at 6 mph. The energy is strong at 4305. The afternoon gets even bigger at 12 ft with an 18-second period and 7414 energy, but it’s onshore with a moderate breeze. This is a beast of a swell, but the wind is messy. It’s going to be a rough paddle and a challenge—only for the experts. This setup might be more interesting for the kite surfers than paddle surfing.
Thursday, August 27th stays big, with 10 ft SW swell both morning and afternoon, but the cross-shore winds make it lumpy. The energy is still strong at 3745 and 3565. Not the cleanest, but there’ll be power.
Friday, August 28th is your next true standout. The morning brings a 7 ft SSW swell with a 13-second period, and it’s a clean offshore breeze from the E at 9 mph. The energy is 1843 (moderate). The afternoon goes glassy again with a 6 ft SSW swell—dead calm. That’s a beautiful end to the week.
The next Monday, September 1st morning is another clean one. A 6 ft SW groundswell with a 16-second period under a light cross-offshore from the SE. Energy is 1431 (moderate). Clean, lined-up waves for the experienced.
Monday, September 7th morning is the biggest standout of the whole forecast. An 12 ft SW groundswell with a 15-second period, offshore breeze from the SE at only 3 mph, and a massive energy of 4455 (strong). The conditions are clean. This is a proper, powerful, long-period groundswell. It’s going to be a big, clean, heavy day. Only for the experts, and it’s over a week away, so keep an eye on the forecast— this one’s promising but not locked in.
Best of the bunch: Monday, August 24th morning for the first clean pulse, Friday, August 28th for the glassy offshore windows, and the Monday, September 7th morning for the biggest, cleanest slab of the run.
Rusty out.

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.
