Thirroul Surf Forecast and Surf Report

Alright, Rusty here lookin’ at the charts for Thirroul over the next couple of weeks. It’s a bit of a mixed bag, so let’s get into it.

First off, the water’s a touch warmer than normal for this time of year, sitting at 66°F with a slight anomaly. That’s a nice little bonus.

The first decent chance we get is actually this Saturday morning, the 4th of July. We’ve got a clean 3 ft swell from the south, with a 12-second period and a crisp cross-offshore breeze from the WSW. Wave energy is moderate (235). It’s not massive, but the conditions will be glassy and clean. Thirroul is a beach and reef setup, exposed to the south-east swell, and with these light winds, it’ll be a fun little session for the intermediate crew. Just keep an eye out – crowds are sometimes an issue here.

After that, things get a bit ordinary. Sunday the 5th sees a big jump in size – 8 ft from the south – but the wind swings onshore and choppy. It stays messy right through the middle of the week. The swell hangs around 7 ft to 10 ft, but it’s all cross-shore or cross-onshore wind, creating a real chop. The wave energy starts getting serious, hitting strong levels like 1653 on Sunday morning and even 3277 on Wednesday morning. That’s a lot of power, but without clean wind, it’s not going to be pretty.

The first real standout comes on Saturday the 11th of July. The morning shows a clean 5 ft south-east swell, with a 10-second period, and a light offshore wind from the NW. Wave energy is moderate (420). The wind is light and clean, so the waves will be nice and lined up. This is likely the best bet in the first week for a fun, manageable session.

We then hit a flat spell. From Sunday the 12th through to Thursday the 16th of July, the swell drops right off—down to 1 ft at times. There are a couple of tiny, clean waves with offshore wind, but honestly, it’s not worth paddling out for.

Now, for the second week, things start to look interesting again. Friday the 17th is small and clean in the morning with a light offshore, but it’s only 2 ft.

The real standout of the whole forecast, though, is Sunday the 19th of July. We’re looking at a solid 13 ft south-south-east swell, with an 11-second period and a clean offshore wind from the west. The wave energy is enormous – 4121, which is very strong. This is proper groundswell. This size is for experienced surfers only—beginners stay well clear. The wind is gentle offshore, so it should be clean and powerful. For the crew that can handle it, this is the session to circle on the calendar. Keep in mind though, a long-period swell like this can break a bit straight at the beach, so the reef and points will handle it better.

Overall, there’s a bit of waiting involved. The best windows are the morning of the 11th for a fun, clean 5 ft wave, and then the morning of the 19th for a serious, big-wave session for the experts.

Stay safe and keep an eye on the horizon.
