Thirroul Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down what’s in store for Thirroul over the next couple of weeks. The first bit is flat and frustrating, but there’s a proper gem waiting if you’ve got the patience.

The opening stretch is a tough watch. From Friday the 7th through Sunday the 10th, it’s tiny, messy, and mostly not worth paddling out. We’re looking at 2 to 3 foot swells with short periods, and only a couple of brief clean windows. Saturday morning the 8th is glassy with a 2 foot S swell, but the period is only 8 seconds and the energy is weak (90), so it’s really just a knee-high dribbler. Sunday morning the 9th looks clean with a 3 foot ENE swell (period 8 seconds), but it’s still pretty ordinary. The combined energy is only moderate (135). Not going to get the blood pumping.

Monday the 10th afternoon offers a glimmer with a 3 foot ENE swell and clean offshore WNW wind at 15 mph, but again, the size and period aren’t there to get excited about. Tuesday the 11th morning is the first real sign of life – a clean 3 foot S swell with an 11-second period and 15 mph offshore W wind. The energy is moderate (236) and it’s the first “expect good surf conditions” call. That’s your best early-week option, but it’s still only waist-high at best.

Then the mid-week drops off hard. Wednesday through Thursday morning is tiny – 0.5 to 2 feet – with nothing doing. But hold on, because Thursday afternoon the 13th is where things start to change. A 8 foot S swell rolls in with an 11-second period, and the combined energy jumps to 1244 – that’s strong. The wind is cross-off from the WSW at 15 mph, so it’s clean. This is not for beginners; 8 feet is big and powerful.

Friday the 14th is the standout. Morning has a 8 foot SSE swell, 11-second period, and 1256 energy, with clean cross-off WSW wind. Then Friday afternoon is where it really shines: a 6 foot S swell, 10-second period, with light offshore W wind at 9 mph. The wave comment says “expect very good surf conditions,” and the energy is still strong (654). The water temp is 64°, which is about average for this time of year. That afternoon session is the one to circle – clean, offshore, and a proper long-period groundswell. This is a classic point-and-reef setup, and that long period will make the waves peel nicely.

Saturday the 15th goes downhill fast as the wind swings southerly and gets messy. The rest of the second week is small, choppy, and mostly not worth it until the very end.

Looking further out to Friday the 21st and Saturday the 22nd, there’s a long-range promise that looks real good. Friday morning the 21st has a 6 foot ENE swell with a 13-second period, light offshore W wind at 6 mph, and excellent surf conditions for experienced surfers – combined energy is 1028. Saturday morning the 22nd is glassy, with a 5 foot ENE swell, 13-second period, and a whopping 1513 energy. That’s a strong, clean groundswell with zero wind. This is a long-period swell, so it’ll be best at the reef. Keep in mind this is over a week away, so it’s promising but not locked in.

Crowds at Thirroul can be an issue sometimes, so for the Friday afternoon session on the 14th and that long-range Saturday morning on the 22nd, expect company. But for quality like that, it’s worth it.

Stay patient, get on that Friday the 14th afternoon, and keep an eye on the 21st and 22nd.

Rusty.
