Ammonias Surf Forecast and Surf Report

Alright, surfers, ol’ Rusty here with the long-range look. Gotta be straight with you – this one’s a tough read for Ammonias. This is a reef setup that really needs the stars to align, and for the most part, they’re just not lining up.

We’ve got a gap right at the start with absolutely no surf on offer through the early part of the window. The first real chance to even think about a paddle comes Wednesday afternoon, the 12th of August, but even then it’s only a marginal 4ft of swell coming from the S with a solid 18-second period. That’s a proper groundswell, with a combined wave energy of 1186 (moderate). The trouble? Wind's cross-shore from the NE at 16 mph, putting a chop on it. It's gonna be a lumpy, tricky one to line up, and honestly, for a reef break, you want that wind either light or offshore. The crowd factor is there too – this spot can get busy, so you’ll be fighting for position in less-than-ideal conditions.

Thursday morning, the 13th, bumps up a touch to 5ft from the S, 16-second period. Wave energy is similar at 1188 (moderate), but the cross-shore wind sticks around. It’s still only a marginal call.

Then we hit a proper rough patch. From Thursday afternoon all the way through to the 24th of August, it's a long stretch of poor surf quality. The swell sticks around but the winds turn ugly, especially around the 15th and 16th where we see 7ft to 8ft of windswell from the ENE with period down around 8 seconds. Combined energy jumps up to 1790 (strong), but with near-gale force cross-onshore winds at 34 mph on the Sunday, it’ll be a total mess. That’s blown-out, choppy chaos, more for the kite crew than anyone on a paddle board.

There’s a bit of a tease toward the end of the window, particularly on Monday morning the 24th of August. We get some long-period S/SSW groundswell around 3ft, but with a 17 to 18-second period. Wave energy is moderate at 1259. The wind is still cross-shore though, so it’s only marginal. For a reef break like Ammonias, that long-period energy can be magic if the wind cleans up, but here it’s just a "could've been" scenario.

The water is sitting at a pretty normal 80° for this time of year, so no surprises there.

Look, the standout moment – and I use that term loosely – is probably the Wednesday morning, the 12th, or Thursday morning, the 13th, if you’re desperate for a paddle. The swell has some proper S groundswell energy, and the period is decent. But the wind is a constant thorn in our side. For a clean session here, we’d need that ENE wind to drop or swing offshore from the NW. As it stands, it’s a long wait for very little reward. Keep an eye on it, but don’t hold your breath.

Rusty.
