Coronation Beach Surf Forecast and Surf Report

G’day, Rusty here, and I’ve been staring at the charts for Coronation Beach. We’ve got a solid 16-day window ahead, but it’s a bit of a mixed bag, so let’s break it down.

First thing you’ll notice is the water temp is sitting right on 68°, which is bang on average for this time of year—no surprises there.

The overall pattern is a long run of SW groundswell, with some serious energy coming through at times. The first few days are a bit of a write-off for clean surf, but we’ve got a couple of standout sessions if you pick your moment.

Saturday 5th September is pretty average. Morning has a 8 ft SW swell at 15 seconds, but with a gnarly 15 mph WNW cross-on wind, it’s choppy and messy. The combined energy is moderate (2579). Not one to rush for.

Sunday 6th September looks better. The swell holds at 10 ft SW, period drops to 13 seconds, but the wind swings SSE at 19 mph, giving us a clean, cross-off breeze. The combined energy is moderate (2912). It’s a big day, though—over 8 ft—so this is strictly for the experienced crew. The morning session is the pick.

Monday 7th September is the first real standout. Morning brings a 10 ft SW swell with a very long 17-second period, and clean SE cross-off winds at 16 mph. The combined energy is strong (4533). That’s a proper groundswell, favouring point breaks and reefs. At Coronation Beach (beach and reef), the long period might make it a bit straight at times, but the power is undeniable. Again, over 8 ft, so experts only. The afternoon turns to junk with a lumpy cross-shore.

Tuesday 8th and Wednesday 9th September stay solid. Tuesday morning has 8 ft SW at 16 seconds, clean with ESE cross-off, and moderate energy (3097). Wednesday morning is the real gem: 8 ft SW at 16 seconds, with a 22 mph E offshore wind—fresh offshore and clean. Energy is moderate (2853). That’s your best early window: clean, powerful, and holding shape.

Thursday 10th September morning is a sweet spot for the less experienced. Swell drops to 5 ft SW at 15 seconds, with a light NE cross-off, and combined energy is moderate (1057). Clean conditions, and at 5 ft, it’s just at the top end for beginners. The afternoon turns onshore and messy, so hit the dawn patrol.

Friday 11th September is a write-off with onshore winds and poor conditions.

Saturday 12th September morning has a 7 ft WSW swell with rain showers and onshore wind—not great. The afternoon is a little better with a light cross-on, but still marginal.

Sunday 13th and Monday 14th September are mostly average, though Monday morning has a clean 8 ft SW swell with cross-off wind—worth a look if you’re keen.

Tuesday 15th September is another standout. Morning delivers a 8 ft SW swell at 16 seconds, with a 12 mph E offshore wind—moderate offshore and clean. The combined energy is strong (3098). This is a proper session for experienced surfers, with power and shape.

Wednesday 16th September morning sees the swell drop to 5 ft SW at 16 seconds, with light NNE cross-off winds and clean conditions. Energy is moderate (1300). A good option for a wider range of abilities.

Thursday 17th September is OK, but the wind is cross-on or onshore, so not a highlight.

Friday 18th September is poor.

Saturday 19th September morning has a 8 ft SW swell at 18 seconds—very long period—with onshore wind. The afternoon bumps to 10 ft SW at 18 seconds, with a light cross-on. Energy is strong (5742). That’s a big, powerful swell, but the wind is not ideal. For experts only, and the long period may make it tricky at the beach break.

Sunday 20th September is the final standout. Morning has 10 ft WSW swell at 16 seconds with light onshore wind, but the afternoon is the real deal: 10 ft SW at 16 seconds, with light onshore wind, and combined energy is very strong (8374). That’s a huge amount of energy. The score is high, but the wind is light onshore, so it could be a bit soft. Definitely for experts only.

Best on offer: The top pick is Monday 7th September morning for the pure power and clean conditions, but it’s for experts. For a more accessible session, Thursday 10th September morning is a gem with clean conditions and manageable size. And keep an eye on Tuesday 15th September morning—another classic for the experienced crew.

Rusty out.
