Thirroul Surf Forecast and Surf Report

G’day, Rusty here.

Alright, look, the next couple of weeks at Thirroul are a bit of a mixed bag. We’ve got a quiet start, then a proper pulse of south groundswell late in the run that’s going to get the blood pumping. If you can hold out, the end of the forecast window is where the real action is.

Tuesday the 21st kicks things off with some clean, surfable waves. Nothing massive, chest-to-shoulder high 4ft from the ENE with a 10-second period, cross-off wind from the NNW, and the water’s sitting at a comfortable 65°, a degree and a half warmer than average for this time of year. It’s not the biggest, but it’s a fun little session with decent energy (387). The afternoon chops up a bit as the wind swings NE.

Wednesday morning the 22nd is a beauty if you can get out early. That same 3ft ENE swell is there, but with a glassy, offshore W wind it’ll be absolute perfection. The energy is moderate (202). Clean lines, no crowds to worry about yet.

The middle of the week from Thursday the 23rd to Sunday the 26th is small. There’s a little bump of S swell on Friday morning the 24th at 5ft but with a short 8-second period, it’ll be a bit weak and wobbly. Saturday the 25th has a S groundswell coming in at 11 seconds (397 energy) but the wind is howling cross-off at 16 mph, so it’s going to be a battle. Sunday the 26th morning is the pick of this average run: clean, 5ft from the S, light SW wind, and solid energy (422). Worth a look if you’re keen.

Then there’s a real lull. Monday the 28th and Tuesday the 29th drop right off. The swell gets tiny—down to 1ft and 0.3ft—with hardly any energy (37, then 22, then just 10). Stick to the land-based activities.

Now, hold on to your hats. On Wednesday afternoon the 29th, things flip completely. We get a sudden jump to 12ft from the S (1936 energy), but the wind is messy and the period is short, so it’ll be a washing machine. Not for the faint-hearted.

But from Thursday the 30th right through the weekend, we are talking about a proper standout. This is what you wait for. Thursday morning the 30th delivers clean 8ft S groundswell at 11 seconds (1456 energy) with light cross-off wind. That's excellent, powerful surf for experienced surfers only. The wave quality is top-shelf. Friday the 31st goes even bigger with a 10ft SSE groundswell, clean offshore W wind at 12 mph, and a massive 1889 energy. This is serious. Saturday the 1st of August starts glassy with a 10ft SSE swell (1717 energy) – absolutely perfect conditions for the experts.

Sunday the 2nd of August is the absolute highlight. The morning sees a 10ft S groundswell, a 11-second period, clean offshore W wind at 16 mph, and combined energy skyrocketing to 3450. That is a serious, powerful, generation-long groundswell. The afternoon holds a 10ft SSE swell with a 12-second period at 3908 energy. This is the kind of day where the point and reef at Thirroul will be absolutely working, with long, lined-up sets. If you don’t have the experience for waves over 8ft, watch from the rocks, because these are only for experts.

The wind turns cross-shore on Monday the 3rd and Tuesday the 4th, dropping the quality, but the swell is still solid at 7ft to 8ft with SE energy (1056 to 1381). It’ll be lumpy and harder to surf. By Wednesday the 5th, the swell fades back to junk.

So the bottom line: the first week is small and average. The second week, from the 30th of July through the 2nd of August, is absolutely firing. Those are your standouts. Thursday the 30th and Sunday the 2nd are the two best on offer.

Rusty.
