Coronation Beach Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks at Coronation Beach.

Right off the bat, we’ve got a proper southwest groundswell winding up. The combined energy is a massive 4533 (moderate to strong wave energy) kicking off the first day, Monday the 7th of September. We’re looking at a solid 10 ft SW swell with a very long 17-second period. That’s proper groundswell, which loves a setup like this beach and reef break. The water temp is 68 °F, which is bang on average for this time of year – no surprises there. The wind is cross-off from the SE at a brisk 16 mph, so it’ll be clean up. But be warned, at 10 ft, this is expert territory. Too big for beginners.

Monday afternoon gets a bit cross-chop with a 22 mph southerly. Tuesday the 8th drops a touch to 8 ft SW swell, still with that long 16 to 17-second period, and a fresh ESE wind keeps it cross-off and clean. Still a big, powerful wave for experienced surfers only.

Wednesday the 9th is a real standout. We’ve got a 7 ft SW swell with a 16-second period, but the morning sees an easterly blowing at 25 mph – that’s a strong offshore wind. It’ll be clean, but at that velocity, paddling out is going to be a serious battle. The afternoon dials it back to 19 mph easterly, still fresh offshore, with 6 ft of swell. The wave energy is still moderate at 1735. It’s doable for the strong paddler looking for hollow, clean walls.

Thursday the 10th is smaller, 5 ft to 5 ft SW, with a gentler breeze. Morning is the pick with a light ENE cross-off, clean surf. That’s a nice window for the confident intermediate.

From Friday the 11th through to the 17th, we hit a sloppy patch. Lots of onshore and cross-on winds, and the swell quality drops away with shorter periods and chop. The 19th of September has a few cleaner morning windows but the swell is smaller and weaker, energy under 1700. Not worth getting too excited about.

Now, here’s the big one to circle. On Monday the 21st of September, we get a proper pulse back. The morning kicks off with a 8 ft SW swell and a *very long* 19-second period. Combined energy is 4385 – strong wave energy. The wind is light WSW cross-on, so a little texture but still rideable. Then the afternoon of the 21st is the absolute standout of the whole forecast: a 12 ft SW swell with an 18-second period, and the combined energy hits a whopping 10896 (very strong wave energy). The wind is onshore WSW at 12 mph, but at that size and period, it will be a heavy, powerful groundswell. This is for experts only.

The following morning, Tuesday the 22nd, it’s blown out with strong cross-onshore wind near gale force and rain. Don’t bother.

Overall, if you’re a strong surfer, the best windows are the 7th and 8th for that big, clean groundswell, and especially the afternoon of the 21st for raw power. Beginners should sit this whole run out.

Rusty.
