Cyrils and Big Left Surf Forecast and Surf Report

G’day, Rusty here, and we’ve got a proper run of surf coming up at Cyrils and Big Left. This reef setup is exposed to the south swell, and the water’s sitting at 56°, which is pretty much normal for this time of year, so don’t expect any surprises there.

The window kicks off Wednesday, August 12, with a 8ft SW groundswell rolling in at 16 seconds. That’s a solid, long-period pulse – perfect for this reef. The wind’s a cross-offshore from the west at 12 mph, keeping things clean, and the combined energy is pumping at 4630. It’s not going to be perfect all day, with tide concerns flagged, but it’s a strong start.

Thursday, August 13, is where it gets proper. The swell holds at 10ft SW, still that long 16-second period. The morning’s got a bit more breeze, but by Thursday afternoon, the wind drops to a gentle cross-off from the west at 9 mph, leaving the waves clean. This is excellent for experienced surfers – the energy’s massive (4523). Friday, August 14, sees the swell holding at 10ft SW, but the wind starts to turn cross-shore and choppy by the afternoon, making it a step down.

Saturday, August 15, the wind swings onshore and the swell drops a touch – it’s messy. Sunday and Monday, into the middle of the week, the swell fades steadily down to 4ft SW by August 18. On Tuesday morning, August 18, we get a little window: 4ft SW swell, light cross-off from the NNE at 6 mph, clean conditions, and a decent energy reading (1100). Best for the experienced again, but much smaller.

Then there’s a quiet spell. From Wednesday, August 19, through to Friday, August 21, the swell drops into the 2ft to 3ft range. Some of those days have good wind, but there’s just not enough push to get excited about. Saturday, August 22, things start to tick up again with a 3ft SW swell that gets a boost to 5ft by the afternoon, clean offshore winds from the NNW, and energy jumping to 1607. That Saturday afternoon is worth keeping an eye on – clean, moderate offshore, and a bit punchy.

But the real standout is way out there. Wednesday, August 26 – two weeks from now – dawns with 12ft SW groundswell, light cross-off wind from the NE at 6 mph, and the combined energy is a staggering 7606. That’s exceptional, expert-only territory. The swell’s well over 8ft, so it’s not for beginners, and the period’s still long at 15 seconds, giving proper, heaving reef waves. Crowds are possible here, but on a day like that, it’ll be only the guns out. It’s a long-range call, so treat it as promising but keep the plans flexible. After that, the swell fades again into the end of the month.

If you’re looking for the best on offer, Thursday afternoon, August 13, and that Wednesday, August 26, are the true standouts. The first is a guarantee, the second is a potential classic.
