The Lowdown
Alright, let’s get into it. Only one break on the map, but when this reef turns on, it’s a proper show. Water temp is sitting a touch warmer than normal for this time of year, around 76°, so no need for the thick rubber.
Tuesday morning, September 15th, we’ve got a beautiful long-period SW groundswell at 5ft, 18 seconds – that’s proper groundswell, wrapping deep into the reef. The combined energy is strong (1726), and with glassy conditions and a whisper of breeze from the ENE, it’s gonna be clean. This is for experienced surfers only. That afternoon, it bumps to 6ft with a dead calm ocean. The energy jumps to 3078 – you’ll feel that in your chest. This is a prime window.
Wednesday the 16th is the big dog. Morning shows 8ft of SSW groundswell at 15 seconds, and the energy is a massive 3221. Glassy glassy glassy. This is serious, powerful reef surf. If you’re not ready for it, watch from the rocks. The afternoon holds 8ft but gets a bit cross-shore, so the morning is the clear winner.
Thursday the 17th settles to 5ft in the morning with glass, then 4ft in the arvo. Still clean, still fun. Friday the 18th is smaller, around 3ft to 5ft, but the afternoon goes glassy with a touch of SSE energy – worth a look.
The weekend gets skinny. Saturday the 19th is tiny, 3ft to 3ft, with a cross-onshore breeze messing up the arvo. Sunday the 20th is better, a glassy morning with 4ft of SW swell and energy back over 600. Stays clean into the afternoon.
Monday the 21st is onshore and messy. Skip it. Tuesday the 22nd is small but glassy. Wednesday the 23rd and Thursday the 24th bring 4ft to 3ft of clean, glassy SSW swell – nice, but not exciting.
Looking further out, Saturday the 26th of September shows a pulse of 6ft, but with cross-shore and onshore winds, it’s looking more like a kite session. Sunday the 27th morning is a different story: 7ft with glassy conditions and energy at 1407 – another one for the advanced crew. Monday and Tuesday the 28th and 29th both have clean, glassy mornings with 5ft to 6ft of quality SSW groundswell. The energy on the 29th is back up to 1724 with a 16-second period. That Tuesday morning looks like a real gem for the second week.
The standouts are clear: Tuesday afternoon the 15th, and Wednesday morning the 16th. The 16th is the biggest, cleanest, and most powerful day of the whole run. After that, Sunday the 27th morning is the next one to circle, but it’s further out, so keep your fingers crossed.
Stay sharp and don’t miss that Tuesday glass-off.
