Thirroul Surf Forecast and Surf Report

Alright mate, let's talk surf for Thirroul. The next couple of weeks are a real mixed bag, with some solid size coming through but the wind is gonna be the main character. Water temp is sitting right on average for this time of year at 64°, so nothing unusual there. The first few days are a bit of a write-off, but things get interesting later on.

Monday morning is looking alright to kick things off. We've got a light NNW cross-off breeze and clean 4ft waves from the NE with a short period of 7 seconds. It's not huge, and the combined swell energy is a weak 283, so it's small and clean – good for a longboard or a fun little grovel session.

Monday afternoon drops right off, with a tiny 2ft from the S and onshore wind, so that's done. Tuesday is pretty flat and messy, nothing to get excited about. The real story starts Wednesday morning. We see a jump to 8ft from the S, but the wind is a strong cross-shore at 16 mph. The combined energy jumps to a strong 1391, but with that wind it's going to be a choppy, lumpy mess. This one is for experts only, and honestly, with that wind, it might be more fun on a kite than a paddle board. Wednesday afternoon is even bigger at 10ft but with a fresh onshore wind – forget about it.

Thursday morning is the first real standout. A solid 10ft S swell with a long period of 10 seconds and only a gentle cross-shore breeze. The combined energy is a very strong 2674. This is proper groundswell energy, and while the wind isn't perfect, it's manageable for experienced surfers. The wave comment says marginal due to tide, so pick your bank carefully. This is your best option for a proper, big-wave session.

Friday morning is another standout, and probably the pick of the first week. The swell drops back to a clean 4ft from the SSE with a 9-second period, and the wind goes completely glassy – zero. The combined energy is a moderate 280, and the water is glass. This will be perfect, clean, and fun for everyone. Get out there early.

The weekend is small and ordinary, with light winds but tiny waves. Sunday afternoon, however, has a real wildcard. A clean 7ft from the SSE with a moderate offshore wind from the NW. The combined energy is 526, and the forecast says “expect very good surf conditions.” This one is a real sleeper for the weekend.

Looking into the second week, things get bigger again. Monday the 21st brings a big 10ft S swell, but the wind is onshore and choppy. Not good. Tuesday the 22nd has a 7ft SSE swell with a very long 12-second period, but a moderate cross-shore wind. That long period is great for the reefs and points, but the wind is a spoiler. Wednesday the 23rd is your next likely winner: 4ft from the SSE with a very long 12-second period and completely glassy conditions. The combined energy is 382. That's a beautiful, clean, long-period groundswell – absolute perfection for a point break or a reef.

The final few days into the end of the month are messy again, with onshore winds and lumpy conditions. The Sunday the 27th afternoon is a potential standout: 7ft from the SSE with a solid offshore wind from the NW, giving you a clean 526 energy. That's a promising finish to the period, but it's a long way out, so keep an eye on it.

So, to sum it up: the best on offer is Thursday the 17th morning for the big wave crew (10ft, clean enough), and Friday the 18th morning for everyone else (4ft, glassy perfection). In the second week, Wednesday the 23rd morning looks like the absolute gem – glassy, long-period, and clean.
