The Lowdown
Alright, this is Rusty. Let's take a look at what's cooking for this stretch.
Honestly, looking at the sixteen days ahead, there's a long, quiet spell on the cards here. For the first two weeks of the period, until the 24th of September, it's dead flat. We're talking tiny little waves from ankle to knee high, mostly messy onshore conditions, and the kind of wind that just doesn't line up. The combined wave energy barely cracks double digits for most of that run, sitting weak as anything. You are looking at a solid gap of around 14 days with nothing worth paddling out for.
Then, on the morning of the 25th of September, things might just start to stir. A small improvement shows up with a 3ft swell from the East, though the period is short at 5 seconds – so no real power behind it. The wind swings around to a light SSE breeze, which is cross-onshore at Octagon House and that will keep things a bit lumpy. The combined energy rises to 56 (moderate), which at least hints at something moving. The water temp is about average for this time of year, nothing weird going on.
Now, Octagon House is an exposed spot that needs the right SE direction to work, and this East pulse isn't exactly on its optimum angle. It's a consistent enough beginner wave, but with the short period and cross-onshore wind, it's not going to be pretty. The energy is just too weak and the wind is too messy to call it a standout of any kind. Honestly, this whole setup looks more interesting for a kite surfer than someone with a paddle, given the beach-and-reef setup and those persistent onshores. There's no real highlight in this entire run – it's just not the time for this coast. Keep an eye on the forecasts, though; it tends not to stay this flat for long.
