Thirroul Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a good hard look at what’s on the table for the next couple of weeks. It’s a mixed bag at best, but there are a couple of windows if you’re keen.

We’re looking at a beach-and-reef set-up that’s exposed to the swell, which is a good start, but for the first few days it’s looking pretty flat and messy. The water temp is sitting at 64°, which is about normal for this time of year. Nothing special to report there.

Monday 14th kicks things off with tiny 2 ft S swell, but that’s about it. The wind is a light cross-off from the N in the morning, so it’s clean, but the energy is weak (152 combined energy). It’s surfable but very ordinary. Afternoon turns to a cross-shore NE wind and a weak 3 ft NE windswell with a shocker 6-second period that just won’t hold a face. Poor.

Tuesday 15th is even worse. Tiny 2 ft NE swell on the morning with a cross wind, and the afternoon gets a bump from the S at 12 mph that just chops everything up. Not worth paddling out.

The first real standout comes in the middle of the week. Wednesday 16th morning is a serious proposition, but only for experienced surfers. We’ve got a solid 10 ft S swell rolling in, with a good 10-second period and a massive shot of energy (1706 combined energy). The wind is a cross S/SW breeze at 19 mph, which is fresh and lumpy, so it’s going to be a battle. That size is definitely expert territory, and the cross-off wind will hold it open but it’s going to be a grinding, heavy day. The afternoon gets worse as it goes cross-onshore.

Thursday 17th is a step down but still has some grunt. A 8 ft SSE swell (930 combined energy) with a light cross S wind in the morning. It’s a marginal call—big enough to be fun for the experienced, but the quality is just okay. The afternoon turns onshore from the ESE, making it a write-off.

Friday 18th morning is your next real highlight. This is the best on offer in the whole forecast. We’ve got a nice, clean 4 ft SSE swell (310 combined energy) with glassy conditions, dead flat wind from the NE. The swell period is 9 seconds, so it’s a decent groundswell that will give you some nice lines at this spot. Crowds are sometimes a thing here, so get in early. This is the session to circle.

The rest of the 18th and the 19th drop off into tiny, weak surf. By Saturday 19th afternoon, you’re looking at 2 ft S swell (79 combined energy) and glassy conditions, but it’s just small and unexciting.

Sunday 20th is almost flat. Truly tiny 1.0 ft S swell and then a laughable 0.7 ft SSE swell with a ridiculously long 20-second period (55 combined energy) in the afternoon. That long period will make it incredibly inconsistent and hard to catch on a beach-and-reef set-up.

Monday 21st afternoon shows a sudden bump to 7 ft SSE swell (710 combined energy) but it’s straight onshore from the ESE. It will be a wind-blown mess. Not good.

Tuesday 22nd morning has a 6 ft SSE swell (770 combined energy) with a nice 11-second period, which means proper groundswell energy. The cross NE wind at 9 mph will create a slight chop, but it’s a decent option for the more experienced. The wave energy is solid, but the quality is marginal.

From Wednesday 23rd right through to the end of the forecast on Tuesday 29th September, it’s a long stretch of poor to terrible conditions. The swell stays small to moderate (mostly 3 ft to 6 ft) but the wind is nearly always cross or cross-onshore from the N/NE, bringing chop and no real quality. A lot of these days have combined energy in the 200-700 range, which is weak to moderate, but the wind just ruins the surface. Sunday 27th and Monday 28th bring rain and stronger S/SE winds on top of it, and that’s just a write-off for paddle surfing. Honestly, that stretch of the 23rd to 29th looks more interesting for kite surfing than a surfboard, especially with the cross-shore wind.

So, to wrap it up: the two true standouts are Wednesday 16th morning if you’re a big-wave hound and can handle the 10 ft close-outs and lumpy wind, and Friday 18th morning for the rest of us, with clean 4 ft glassy lines. After that, it’s a long, frustrating gap of poor conditions.

Rusty out.
