Thirroul Surf Forecast and Surf Report

Alright, Rusty here again. Let's talk about the coming couple of weeks for the Thirroul stretch in units the old-timers might like.

It starts off slow, but there's a big thump of swell coming later. The water's sitting at about 65°, which is right where it should be for July—no anomalies to report.

The 21st of July is a rough Tuesday. There's a 4ft ENE swell at 10 seconds, but a cross-breeze is making a mess. Combined swell energy is weak (359)—not worth suiting up. But Wednesday the 22nd turns it around. The swell is smaller at 3ft ENE, but we get a light offshore wind in the morning and cross-off in the afternoon, so it cleans right up. Moderate energy (204-202) makes for a fun session on the beach and reef. Thursday the 23rd sees the swell drop with stronger W winds, leaving only 3ft of junk—too weak to care about.

Now, here's the first standout. Friday the 24th, a south swell arrives. The morning brings a solid 8ft S swell at 9 seconds, with a clean cross-off breeze. The energy jumps to strong (1325). It's over 5ft, so beginners should stay out. Then Friday afternoon goes glassy with a 6ft S swell at a longer 11-second period. Energy is still strong (895). That is clean, lined-up surf, and it'll be a proper treat. The S swell direction suits Thirroul, and glassy conditions are a bonus.

Saturday the 25th and Sunday the 26th are more marginal. The S swell eases with moderate winds and energy dropping (447 to 284). It gets a bit choppy. The 27th and 28th of July are flat—tiny energy down to 17 on the Tuesday.

We get a tiny glassy wave on the 29th (1ft, 46 energy) but nothing special. Then, hold tight for Thursday the 30th of July. The morning brings a massive 12ft S swell at 11 seconds. The combined energy is very strong at 4769, and the offshore wind keeps it clean. This is expert-only, over 8ft, and carrying a lot of power. The afternoon hits 13ft S swell at 12 seconds (6165 energy), though a cross-shore breeze picks up. That's a major south groundswell event. Friday the 31st has another clean 10ft SSE swell with offshore winds (2388 energy)—again, only for experienced surfers.

The first week of August still has size but gets messy. The 1st of August has 8ft to 7ft SSE swell, but cross-onshore winds make it choppy. The 2nd drops to 6ft with a light cross-shore. The 3rd and 4th of August see the swell ease to around 3ft SSE with clean morning windows and moderate energy (200-300 range). It's ordinary but rideable. The 5th of August fades to small 3ft SE swell with strong winds.

So, the best options: Friday the 24th of July afternoon is a standout with glassy 6ft south swell. The absolute highlight is Thursday the 30th of July morning—a massive 12ft S groundswell under offshore wind, but only for the experts. That'll be a day with plenty of grunt and clean walls.

Rusty.
