The Lowdown
Alright, Rusty here again, giving you the same picture in feet and miles. We’re looking at Octagon House, and it’s a long, quiet outlook.
The first week and a half is a real bummer. From Friday, August 28, right through to Wednesday, September 9, it’s tiny, weak, and messy. You’ll see a few glassy mornings, but the swell is barely a ripple – 0.3ft to 2ft, mostly from the southeast, with a short period of 3 to 6 seconds. The combined energy is low, between 3 and 28 (barely a whisper). The winds are mostly onshore or cross-onshore, and the water is a touch warmer than normal for the time of year, about 87°F.
There’s a big gap of nearly two weeks with nothing worth paddling for.
Then, on Thursday, September 11, in the morning, we get a tiny window. The swell comes up to 4ft from the SSE, with a 7-second period. The combined energy hits 153 (moderate). The wind turns light offshore from the WNW, and it’s clean. That’s a surfable session, but it’s not a standout. The water temp anomaly isn’t given for that date, but it’s likely still warm.
The next morning, Saturday, September 12, also shows clean conditions with a light cross-offshore wind from the west and a 3ft SSE swell, but the energy drops to 75 (weak). Again, surfable, but nothing to write home about.
Honestly, there’s no big winner here. The best you’ll get is a couple of clean mornings with small, slow waves. For a beginner, that 4ft on the 11th might be okay, but the short period means it’ll be a bit lumpy. For everyone else, it’s a waiting game. Forecasts can change, so keep your hopes up, but right now, it’s a quiet stretch.
Rusty.
