Coronation Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of south-west groundswell on the way for Coronation Beach, starting on Thursday the 20th of August. This isn’t a quick pop of energy; it’s a sustained pulse with some serious grunt, especially for the experienced crew. The water temp is sitting at 67°, which is a touch cooler than average for this time of year, so don’t expect a tropical bath.

The action kicks off Thursday morning with an 8ft south-west swell, riding a long 16-second period. The combined energy is a hefty 3710 (moderate to strong), and with a light cross-off breeze from the SE, it’ll be clean. This is a big wave for a beach and reef setup, so it’s strictly for the experienced surfer. The morning is the pick; the afternoon sees the wind swing SSE and bump up to 19 mph, making it a lot messier.

Friday morning stays strong, dropping just a little to 8ft from the SW, still with a very long 15-second period, and a light offshore from the ESE at 9 mph. The energy is still high at 2482. This is another excellent window for the confident surfer. The wind holds through the day but gets stronger and cross-off in the afternoon, so stick to the early session.

Then we get a real treat. Saturday morning, the 22nd of August, the wind goes glassy. Completely calm. The swell settles to 5ft, but the period stretches to 18 seconds, and the energy is still pumping at 2572. This is the standout of the whole run. Clean, long-period groundswell, no wind, and the size is manageable for a wider range of good surfers. This is the session to circle. The afternoon gets chopped by a cross-shore, so Saturday morning is the absolute winner.

The consistency holds through the weekend, but the quality drops a bit. Sunday is blown out with a fresh cross-shore, and the swell drops to 4ft. Monday morning the 24th gets a nice clean up with a 7ft SW swell and a light cross-off breeze, scoring 1863 energy – a solid, clean option for the experienced.

We hit a bit of a lull mid-week. Tuesday the 25th sees the swell drop to 4ft and the period shortens, with weaker energy. Wednesday the 26th looks like a big clean-up day, but with strong onshore winds, the quality is poor. There’s a gap of a few days of less-than-ideal conditions.

The next real standout is a week later, on Sunday the 30th of August. The morning is glassy again, with a pumping 8ft south-west swell and a 19-second period. The energy is massive at 4219. This is a serious, powerful groundswell with perfect glassy conditions – a top-shelf option for the experts. The afternoon picks up a light cross-onshore, so again, morning is the key.

The pattern continues into the first week of September. Monday the 31st of August and Tuesday the 1st of September both have glassy starts with solid 7ft to 8ft swell, but the wind tends to be more cross-onshore. The energy is still very strong, in the 2000 to 4000 range. The best window remains the early mornings.

After that, the wind turns more consistently onshore from the west from the 2nd of September onwards, and the swell becomes a bit more unreliable. The last couple of days of the forecast, the 4th of September, see a return of a clean 8ft swell with a light cross-off, but the energy is still high. It’s a late call, but one to watch.

Bottom line: the absolute best of the best is Saturday morning the 22nd of August with its glassy conditions and long-period swell, and Sunday morning the 30th of August for the massive, clean groundswell. The early mornings are your friend throughout this whole outlook.

Rusty.
