Ammonias Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s get straight into it. We’ve got a sixteen-day window for Ammonias, and I gotta be honest with you—it’s looking like a bit of a tough stretch. There’s no surf worth paddling out for right from the get-go, and we’re staring down a long, dry gap.

The overall pattern is dominated by messy, short-period windswell and cross-shore breezes that are just killing any chance of a clean wave. The water temp is sitting at 81°F, which is bang on average for this time of year, so at least you won’t be cold while you’re sitting there watching the chop.

Ammonias is a reef break that’s fairly consistent, but don't let that fool you. The first real sniff of anything comes right at the end, on the 8th and 9th of September. But even then, we’re looking at lumpy, crossed-up conditions with moderate to fresh breezes. The swell around the 6th and 7th of September has some decent energy—combined energy values reaching 1160 and 1376—but it’s all short-period stuff from the ENE, cross-on at times, and the reports are pretty clear: it’s marginal at best. You’d be scratching for a half-decent one.

The real standout, and I mean the only one worth circling on your calendar, is the 5th of September. The Saturday morning session shows a 6ft swell from the ENE with an 11-second period. That’s a proper groundswell, and the combined energy is a solid 1160. It’s still cross-shore, but it’s the best-looking window for any sort of shape and push. It’s not perfect, but it’s the pick of a pretty unattractive bunch.

The rest of the run is a write-off. Persistent moderate cross-shore winds and short-period junk. Plan your days around something else, because this forecast is lean. The long-range stuff on the 11th shows a strong offshore wind, and while that cleans things up, the swell's gone soft and the period is only 8 seconds—not worth the fight.

So, for now, keep your expectations below sea level. If you’re desperate, Saturday the 5th of September might just give you a couple of corners to work with.

Rusty.
