Duppys Surf Forecast and Surf Report

Alright, let’s get into it. The 16-day window starts now and honestly, mate, it’s a bit of a slow grind to kick things off. We’re at Duppys, a reef break that’s pretty consistent and takes a north swell, so it’s a spot that can work when others don’t. The water temp is sitting at 84°, which is about normal for this time of year, so no worries there.

For the first week, from the 26th of August right through to the 2nd of September, it’s pretty grim. We’ve got a long stretch of mostly poor surf, with tiny little waves and fresh cross-off or offshore winds that keep the surface clean, but there’s just no energy in the water. On the 26th and 27th, we’re looking at 1 foot of north-east swell with a very long period around 15-16 seconds, but the combined energy is weak (45 to 140). That long period stuff is classic groundswell but it’s just too small to do anything. The 28th isn’t much better. The 29th sees a bump to 4 feet, but the period drops to 7 seconds – that’s short-period windswell, poor shape, and energy is still moderate at best (234). It’s not worth paddling out.

Then on the 30th of August, we finally get a bit of a pulse. Sunday afternoon sees swell jump to 7 feet from the east-north-east, with a period of 11 seconds and a combined energy of 877 – that’s moderate to strong energy. The wind is cross-off from the SE, so it’s clean. The problem is, the quality is still rated as marginal, and 7 feet is getting into the solid range, so it’s not for beginners. For experienced surfers, this might be the only real option in the first week, but don’t expect perfection.

Monday the 31st has a morning window with 5 feet from the ENE, 9-second period, and offshore winds from the ESE – that’s semi-clean, but the energy is moderate (434) and the period is a bit short. The rest of that day and the next few days drop right back to almost nothing. From the 1st of September to the 7th, it’s a proper blank run. Swell sizes are mostly 0.3 feet to 0.6 feet, with combined energy in the single digits or low tens. It’s basically flat.

Now, looking further out, the 9th and 10th of September start to show some promise. On Wednesday the 9th, we’ve got a morning pulse of 1 feet from the north-north-east, with a very long period of 16 seconds and moderate energy (172). It’s small, but the offshore winds from the east keep it clean. That’s a long-period groundswell, which is great for a reef like Duppys, but it’s tiny. Then Thursday the 10th picks up to 3 feet from the north-north-east, with a 12-second period and moderate energy (376). The winds are cross-off, so it’s clean. This is the best-looking option in the whole 16-day run, but it’s still only small and it’s a long way out – so consider it a promising but uncertain prospect.

All in all, if you’re desperate, Sunday the 30th of August is the only real standout for size, and Thursday the 10th of September for the best conditions with that long-period groundswell, but neither is a classic. Most of the window is a write-off.
