Thirroul Surf Forecast and Surf Report

Grab your board, but don’t get too keen just yet—this stretch ahead is a proper mixed bag. For the next few days, Thirroul is going to be fighting a messy, cross-shore wind that’s chopping up whatever swell is pushing in. Tuesday morning has a bit of energy—7ft of short-period SSE swell, but that south breeze is blowing straight across it, so it’s lumpy and hard to love. The water’s sitting at 64°, which is pretty much bang on average for this time of year, so no surprises there. The afternoon drops a touch to 6ft, but the wind swings onshore, so it stays ordinary.

Wednesday turns properly bleak—morning drops to 3ft with more cross-shore wind, and by the afternoon a fresh southerly kicks in, the swell jumps to 8ft, but it’s cross-onshore and lumpy. Honestly, that’s more of a mess than a session. Thursday shows a bit more size—8ft in the morning from the south with a 10-second period, and the energy’s building (1219 combined), but the wind is still cross-shore, so it’s a grindy, bumpy affair. Not worth getting excited about.

Friday is more of the same—6ft in the morning, cross-onshore, choppy. The afternoon cleans up slightly with lighter onshore flow at 5ft, but it’s still marginal. Saturday morning is actually the first real glimmer: the wind turns cross-offshore out of the north, the swell settles to 4ft from the SSE with an 11-second period—cleaner, more lined up, and the energy drops to a more manageable 390 (moderate). That’s the pick of this first chunk, but even then, it’s not a standout, just a bit more user-friendly. The afternoon fades fast to 3ft and cross-shore junk.

Sunday and Monday are small and poor—nothing over 3ft, a few clean spells but barely a ripple. The water stays average, the crowds are possible if anyone bothers, but honestly, you’re better off finding something else to do. Tuesday the 15th turns weird: morning is flat and choppy, but the afternoon jumps to 6ft of short, south-southeast windswell with a 7-second period, still cross-onshore. It’s raw, weak energy (413 combined) and messy—more of a windblown bump than a proper wave.

Wednesday the 16th has a touch more hope—5ft in the morning with a 13-second period, but it’s still cross-onshore and fairly choppy. The afternoon lightens up with onshore flow and 5ft, but it’s not clean. By Thursday and Friday, it drops back to ankle-biters, though Friday afternoon actually throws a surprise: 5ft of short-period NE windswell, clean with a light cross-offshore breeze (233 combined). That’s a small, clean novelty—worth a paddle if you’re desperate and the banks are friendly.

Then the real lull hits. From Saturday the 19th through Monday the 21st, it’s all under 5ft, mostly weak NE windswell with poor wind direction. No energy, no shape, and the wind keeps messing with it. The 22nd builds a bit of NE swell to 6ft but again, cross-shore winds and messy conditions. The 23rd stays in the 4–5ft range, still NE windswell, but the wind never offers a clean session.

So, bottom line: the only real highlight on offer is Saturday morning the 12th—4ft of clean SSE groundswell, light offshore breeze, 11-second period, and moderate energy. It’s not going to blow your mind, but it’s the most surfable window in a week and a half of slop. Beyond that, we’re looking at a long, empty 4–5 day stretch from the 19th to the 21st where there’s barely anything worth paddling out for. Unless you’re a kiter, and then Thursday the 10th or Tuesday the 15th might look more interesting—those cross-onshore lumps have some push but no shape for a surfboard.

Keep an eye on the longer range—by the 23rd there’s a bit of NE energy, but it’s still wind-affected. Near-term is the only call that feels solid, and even that’s just a fair-to-middling session. The forecast can change, but right now, this stretch is about patience, not perfection.

Rusty.
