Ammonias Surf Forecast and Surf Report

Alright, Rusty here, let’s have a look at what’s on offer.

Honestly, Ammonias is a reef setup that’s mainly for intermediate surfers, and it’s fairly consistent, but the wind window is a bit touchy. The water temperature is sitting at about 80°, which is about average for the time of year, nothing unusual there.

We’ve got a bit of a wait for the good stuff. The first few days are a write-off. Tuesday the 28th has some solid swell energy, about 6ft from the east, with a decent 13-second period, but the wind is cross and gusty, so it’s messy. The energy is strong at 1461 (moderate to strong). By Wednesday morning the 29th, things start to clean up nicely. The wind swings to a light cross-offshore from the NNE, and the swell holds at 7ft from the east-northeast, period 11 seconds, energy 1160. That’s a clean, punchy wave for experienced surfers. Wednesday afternoon stays clean with a light breeze and a 7ft swell. That’s your best window in the first week.

Then Thursday the 30th through to the end of the first week and into the second week, the wind goes onshore or cross-shore, mostly fresh breezes, and the swell gets lumpy and choppy. The energy drops off, and the wave quality is poor. There’s a long stretch from Thursday afternoon all the way through to Sunday the 10th of August where it’s just not worth paddling out. Mostly moderate to fresh cross-shore winds, short period swell between 7-8 seconds, and the consistency is ruined by side-chop.

Now, looking into the second week, there’s a glimmer. On Monday the 10th of August morning, the swell direction flips to the SSW, with a very long period of 17 seconds and energy at 1698 (strong). The wave height is only 4ft, but that long period means it’s a groundswell. This kind of swell can be tricky at beach breaks, but at a reef like Ammonias, it could shape up nicely. The catch is the wind is a fresh cross-shore, so it’ll be lumpy. Monday afternoon stays similar. Tuesday the 11th and Wednesday the 12th have similar long-period SSW and S swells, but the wind stays onshore or cross-shore, so it’s a bit of a fight.

The standout, if you can pick it, is still Wednesday morning the 29th of July. The swell is 7ft from the east-northeast, the wind is light and cross-offshore, and the energy is solid. If you’re an intermediate or better, that’s the one to aim for. The long-period groundswell around the 10th of August is interesting, but the wind needs to drop for it to be a true gem.
