Thirroul Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what the next couple of weeks are shaping up like for our stretch of coast.

We’ve got a bit of a slow start, but there are some definite windows of clean surf if you’re keen to pick your moments. The first week has a few mornings that will be worth the early alarm, with the second week looking a bit more hit-and-miss, though the opening of September brings a little bit of a tease.

Right off the bat, Sunday the 23rd of August morning, Thirroul is offering up a sneaky little session. We’ve got a 3.6ft swell pushing in from the south, and with a light northerly cross-offshore breeze, it’s going to be clean. The combined energy is sitting at a moderate 215, so there’s a bit of push behind it. Water temp is 64°, which is pretty much spot on for the time of year, nothing unusual there. This is a beach and reef setup, so it can handle a bit of south swell. Crowds are sometimes an issue here, so if you see a few others out, don’t be surprised.

Monday morning the 24th is another one to look at. The swell drops a touch to 2.3ft from the south, but the wind swings northerly again, keeping it clean. The energy drops a bit to 201, but for a smaller day, it’ll be fun on the right board.

The standout of the first week, without a doubt, is Thursday morning the 27th of August. The wind goes dead calm – glassy conditions – and we’ve got a solid 4.3ft south swell rolling in. The combined energy jumps up to 284, which is the strongest we see in the first few days. This is the pick of the week, no question. Clean, lined-up south swell with zero wind is hard to beat around here. Get out there if you can.

Friday the 28th morning is another glassy one, but the swell is a bit smaller at 3ft from the south, energy at 208. Still a fun little session before the wind gets messy later.

Now, looking further ahead, the start of the next week has something interesting. On Monday the 31st of August morning, we’ve got a tiny 1.6ft swell, but listen to this – the period is a massive 19 seconds, and it’s glassy. That’s a very long period groundswell, and the energy reading is actually the highest in the whole forecast at 300. Now, with a period that long, these waves can be a bit tricky on a beach break, they might stand up and close out. But if you get a peak that works, they’ll have serious push for their size. Worth a look, but be ready for some weird ones.

Then, on Tuesday the 1st of September morning, the wind goes offshore from the northwest, and we get a 2.3ft south swell with a 13-second period. Combined energy is 215. This is promising, but we’re over a week out, so treat it as a potential bonus rather than a sure thing.

The second half of that week, from the 2nd of September onward, looks pretty ordinary. Swell sizes drop right off, energy readings fall below 100 into the weak zone, and the wind is all over the shop. A couple of mornings on the 3rd and 4th have clean offshore winds, but the swell is weak and short-period. Not really worth getting excited about.

So, to sum it up: Thursday the 27th of August morning is your absolute best bet – glassy, solid south swell, and good energy. Sunday the 23rd and Monday the 24th are solid morning options too. The long-period event on the 31st of August is a wildcard, and the 1st of September has potential if it holds.

Stay frothy.
