The Lowdown
Right off the bat, we’ve got a solid run of surf on the cards at Cozies and Geeries. It’s a reef and point setup that’s exposed to the WSW swell, and while it’s not the kind of spot that’s breaking every day, the windows we’ve got over the next week and a half are worth keeping an eye on. The water’s sitting about average for this time of year, so no surprises there.
Monday, September 14 kicks things off with a proper pulse. Morning sees 7.5ft of WSW groundswell with a 14-second period, and a light ESE offshore breeze is keeping things clean. The energy’s solid—2027 on the combined scale—and while it’s a bit much for beginners, anyone with a few seasons under their belt is going to be grinning. The afternoon holds up similar size, 7.2ft, still offshore, still clean. This is the kind of day you call in sick for.
Tuesday, September 15 stays in the game, though it drops a touch. Morning is 6.6ft, clean again with a gentle E cross-offshore breeze. The afternoon gets a bit bumpier as the wind swings ESE and picks up to 25 km/h, but it’s still surfable. Not a standout, but a solid session if you can get out early.
Wednesday, September 16 is the first real dip. Swell backs off to 4.3ft in the morning with a NE crosswind, and the energy drops under 600. It’s grovelly, but the afternoon shows a bit of life at 3.9ft with a light SW cross-offshore. Small, but clean.
Then Thursday and Friday the 17th and 18th turn messy. Thursday’s got onshore NNW wind at 25 km/h, waves around 3.3ft, and it’s chopped up. Not worth paddling out. Friday gets worse before it gets better—a fresh N cross-onshore at 35 km/h swings to a near gale NNW at 50 km/h by the afternoon, with 10ft of short-period W windslop. That’s blown out, lumpy, and ugly. This is kite-surfing territory, not surfing.
Saturday, September 19 the swell jumps back up to 8.2ft, but the wind’s all over the place—cross-shore WSW at 30 km/h in the morning, cross-onshore in the afternoon. It’s lumpy and choppy. The energy’s big, 2679, but the quality isn’t there. Pass.
Sunday, September 20 is still messy, 6.2ft in the morning with a NNW cross-onshore, then dropping to 4.3ft by the afternoon with a WSW cross-onshore. Some size, but not clean.
Now here’s where things get interesting. Monday and Tuesday, September 21–22, the swell eases and then rebuilds. Monday’s overcast with 5.9ft onshore in the morning, but Tuesday morning brings a clean 5.9ft with a SSW cross-offshore breeze. The afternoon bumps to 6.6ft, still cross-offshore. The period’s up to 15 seconds, so there’s real push behind it. It’s not perfect, but it’s a lot better than the previous days.
Wednesday, September 23 is a proper highlight. Morning has 6.2ft of WSW groundswell at 14 seconds, light E cross-offshore wind, clean conditions, and the energy’s sitting at 2042. This is a great session if you can get out. The afternoon eases slightly to 6.2ft but the period extends to 15 seconds.
Thursday, September 24 keeps the run alive. Morning is 7.2ft at 15 seconds, NE cross-offshore at 20 km/h, clean. The afternoon drops to 6.6ft but stays clean with a SSW cross-offshore. Two solid days back-to-back.
Friday, September 25 the size eases a bit—4.9ft in the morning, 4.6ft in the afternoon—but it’s still clean with a gentle SSW cross-offshore. Not a standout, but a fun, mellow session.
Now, the real gem of this whole stretch lands on Saturday, September 26. This is the one to circle. Morning has 5.2ft with a 21-second period—that’s very long-period groundswell, and the energy is
