Ammonias Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the cards for Ammonias over the next couple of weeks. It’s a mixed bag, so bear with me.

Right off the bat, the first few days are a bit of a struggle. We’ve got some small swell rolling in on Monday the 10th, 2ft to 3ft from the SSW, but the wind is a cross-shore from the ENE at 12 mph, making for a messy, cross-chop surface. The combined swell energy is moderate at best (606-557). It’s surfable if you’re desperate, but it’s not going to be pretty. Tuesday the 11th is much the same story, with a bit more wind making it even choppier in the morning. Wednesday the 12th sees a pulse of new longer-period S swell (18 seconds) pushing the height up to 3ft – 4ft, but that cross-onshore wind keeps the surface lumpy. The energy ticks up to moderate (1119-1193), but the quality is just not there.

Thursday the 13th and Friday the 14th stay in that 4ft to 5ft range from the S, but that fresh NE breeze on Friday (18 mph) is going to wreck the surface completely. You’ll be fighting a lumpy cross-chop.

Now, here’s the first standout. Keep an eye on Saturday the 15th and Sunday the 16th. We get a shift in the swell direction to the ENE. Saturday morning sees about 7ft from the ENE with a short period (8 seconds), but by the afternoon the wind goes cross-offshore from the NNE at 15 mph. That’s clean! Sunday the 16th is similar, with the swell building to a solid 10ft from the ENE, period stretching to 13 seconds, and more of that sweet cross-offshore breeze (NNE 18 mph in the morning, NNW 15 mph in the afternoon). The combined swell energy jumps to very strong (2811-3223). However, that 10ft is getting big for the average punter – this is expert territory. And with that long period (12-13 seconds), it'll be lining up nicely, but at a beach break like this, it might be a bit straight and dumpy. Still, if you’ve got the skills, Sunday afternoon is your window.

Then things go a bit mad. Monday the 17th throws a massive 20ft ENE swell at us with a combined energy reading of 9177 – we’re talking very strong, serious power. But it comes with a cross-shore wind and a risk of thunderstorms. That’s big, dangerous, and messy. The afternoon drops to 18ft from the E, but the cross-onshore wind from the S makes it a washing machine. This setup looks way more interesting for kite surfing than paddle surfing.

After that chaos, the second week settles right down. Tuesday the 18th sees the swell drop back to 5ft – 6ft from the ENE, with periods under 10 seconds. The winds are onshore or cross-onshore, so the quality is poor. Wednesday the 19th is much the same with weak, short-period wind swell.

Things get quiet toward the end of the week. Thursday the 20th and Friday the 21st see the swell shrink to 2ft – 2ft, but the direction swings back to the SSW with very long periods (18-19 seconds). The energy is weak though, and the cross-wind keeps it choppy. Saturday the 22nd is the flattest day of the run, with only 2ft – 2ft of weak, short-period junk.

Into the final week of the forecast, we get another promising pulse. Sunday the 23rd and Monday the 24th see the SSW swell build back up, with periods jumping to a very long 18-22 seconds. By Monday morning we’re looking at 6ft from the SSW with a period of 18 seconds and combined energy hitting 2456 (strong). The wind stays cross-shore from the ENE, so it won't be glassy, but for a point or reef setup, that long-period groundswell would be a dream. At Ammonias, a reef break, this is the kind of window that gets the blood pumping. That 6ft with a long period will have some real grunt and shape. Tuesday the 25th holds at 5ft from the SSW with 16-second periods, still solid but easing.

So, the two honest standouts here are Sunday the 16th for the big, clean, expert-only ENE swell, and then Monday the 24th for the long-period SSW groundswell that should deliver the best combination of size, power, and shape for the more experienced crew at the reef.
