Ammonias Surf Forecast and Surf Report

Right, let’s have a look at what’s cookin’ at Ammonias over the next couple of weeks. First thing first – there’s no surf worth paddling for right this minute, and honestly, it’s gonna be a bit of a wait. We’re staring at a long gap here, with barely a score worth getting wet for until we get deep into the first week of September. For a reef setup like this, that’s pretty normal when the trade winds lock in and the swell angles stay unfavourable. Hang tight.

Starting things off on Saturday the 22nd of August, we’ve got a modest 2ft SW groundswell rolling in with a long 16-second period. That’s a proper long-period groundswell with moderate energy (515) but the cross-on wind from the ENE at 12 mph is mucking it up – choppy, poor conditions. Not one to chase.

Through the rest of August, the swell picks up a bit but the wind stays cross or cross-on, mostly from the ENE at 12–16 mph. On Sunday the 23rd, there’s 6ft from the east with a short period of 7 seconds – weak, lumpy, no shape. That’s more of a messy beach-break vibe than a reef wave. The combined energy nudges into the moderate range (681) but it’s still marginal at best.

The story doesn’t really change through the end of the month. We get pulses of longer-period S and SSW swell around the 26th and 27th – 2ft to 3ft at 14–18 seconds – but that cross-shore wind keeps it average. The energy climbs a bit – up to 759 on the Thursday morning – but it’s still just marginal. The reef likes a cleaner window, and it’s not getting one.

Toward the start of September, we start to see a shift. On Tuesday the 1st of September, the morning is still cross-shore with a 6ft ENE swell at 10 seconds (strong energy, 1196), but by the afternoon the wind goes cross-off from the NNE at 12 mph, and the swell drops to 6ft – cleaner, but only a marginal score. Then we hit the standout.

Wednesday the 2nd of September is the best we’re gonna get. Morning session sees a 3ft S groundswell with a long 17-second period, light cross-off breeze from the NNE at 9 mph, and the wave comment says “expect very good surf conditions” – that’s gold. The combined energy is moderate (604). By the afternoon it gets even lighter, with a 6 mph cross-off breeze and 3ft S swell at 16 seconds, energy up to 709. This is clean, glassy, proper reef-swell stuff. This is the one to circle.

After that, we fade back into marginal and poor conditions again from Thursday the 3rd onward – cross-on winds, 6–7ft short-period ENE swell, and the usual chop. The last bit on Sunday the 6th of September is just poor with moderate cross-on wind.

So, the takeaway? If you’re keen on Ammonias, wait for Wednesday the 2nd of September. That’s the clear standout. The rest of the window is mostly a write-off – a long, frustrating gap with only that one real highlight.
