Ammonias Surf Forecast and Surf Report

Alright, folks, let's get into it. Rusty here, and I've got the full 16-day picture for you. Honestly, looking at the charts for Ammonias, it's a bit of a tough stretch. The conditions are messy for the most part, with a lot of lumpy, cross-shore wind messing up the surface. The water's sitting at a pretty standard 80°F, which is pretty much bang on average for this time of year, so no surprises there.

The opening days are a write-off. We've got a moderate swell running, around 8ft to 8ft on Sunday, but it's short-period, 8 seconds, and those cross-shore winds are just chopping it all up. The energy is moderate (1066), but the quality is poor. Monday and Tuesday aren't much better. The swell drops a bit, but the wind stays on the cross, making for a lumpy, uninviting ocean. The combined energy drops into the moderate range (down to 454), but it's still not clean.

We do get a bit of a glimmer later in the week, though. On Tuesday, the 4th of August, the swell period jumps up to 12 seconds in the morning. That's a groundswell pulse, and the height is a manageable 5ft. The energy is moderate (673). The wind is still cross-shore, but it's a gentler breeze, so the chop won't be as aggressive. It's still marginal, but the longer period will give the waves better shape. Keep an eye on that Tuesday morning window.

The following week is a real mixed bag. The wind is persistent from the ENE, keeping things choppy. There's a brief pulse of long-period swell from the SSW around the 10th and 11th, with period up to 16 seconds, which is long-period groundswell. The energy is moderate (595 to 639). This kind of long-period swell can work well at a reef break like Ammonias, which is exposed to the SSE. The wind is still a factor, making it marginal.

Then, around the 12th of August, we see a bigger groundswell from the south, with a period of 17-18 seconds and a wave height of 4ft. The combined energy jumps up to 1165, which is a strong energy reading. This is the most powerful swell of the whole period, but the wind is still cross-shore or cross-onshore, so it's going to be a battle with the chop. It's likely too small for the bigger energy to really show, but the potential is there.

The very end of the outlook, around the 17th of August, shows a bigger swell of 8ft from the ENE, but still with a short period of 8 seconds. The wind finally eases a bit, becoming a light breeze, but it's still cross-onshore. The energy is strong (1213), but the short period and wind direction mean it's going to be a messy, walled-up wave. That's strictly for the experienced crew.

Overall, the best bet in this window is that Tuesday the 4th of August morning for the slightly longer period waves, or the long-period SSW groundswell around the 10th and 11th if you're willing to roll the dice on the wind. It's not a classic period, but there are a few windows to sneak a wave.

Rusty.
