The Lowdown
Alright, Rusty here. Let’s break it down.
The pick of the run is Sunday morning, September 13th, at Wainui Beach - Stockroute. Clean 5ft SSE groundswell, with a real long 15-second period, and a light offshore breeze out of the WNW. Water temp is 55°, which is a bit colder than usual for this time of year. The wave energy is strong, reading (1175). This one’s for the advanced crew—big, powerful, and clean.
Sunday afternoon gets wrecked as the wind picks up from the south, turning it choppy.
Monday morning, September 14th, is still solid. Swell drops a little to 5ft from the SSE, 12-second period, with a light cross-off wind from the NNW. Clean again, with moderate energy (773). Not as heavy as Sunday morning, but still a great session.
Tuesday morning, September 15th, gives you a smaller, cleaner option. 3ft SSE swell, 11-second period, light cross-off northerly breeze. Low energy (247). Good for a longboard or a funboard.
After Tuesday afternoon, it goes quiet and small for a few days, with nothing much happening until Saturday afternoon, September 19th. That afternoon goes glassy with a 5ft SSE swell, but the period is short at 7 seconds, so it’ll be a bit shifty. Moderate energy (441).
Another quiet stretch until Thursday morning, September 24th. Glassy again, with a 3ft SSE groundswell, 15-second period. Moderate energy (428). Clean, but small.
The biggest swell hits Tuesday, September 22nd, with 8ft to 10ft from the SSE, but strong winds ruin it. That’s expert-only and messy.
Your best call: Sunday morning, September 13th. Don’t sleep on it.
Rusty.
