The Lowdown
Alright, Rusty here. Let's get real about this outlook.
Alright, grab a seat, because the next 16 days are looking pretty grim for Octagon House. We've got a flat spell stretching out in front of us that's hard to ignore. The swell is tiny, and most of the time the wind is just not playing ball. It's a tough stretch, and I gotta be honest with you.
The only real window of anything that resembles a wave comes right at the start. On Saturday, September 5th, the morning is glassy with a light NW wind, but the swell is a pathetic 1 ft from the south, with a short period of 4 seconds. The combined energy is a measly (3), so it's just not enough to push anything. The water is a touch warmer than normal at 87°, but that's about the only positive. The rest of that day, and the whole of Sunday, Monday, and Tuesday, are just flat and poor. We get a few glassy mornings, but the swell is so small, it's not worth a paddle.
The most notable thing is a slight bump in the swell on Monday, September 14th and Tuesday, September 15th, where the swell height climbs to 3 ft and 2 ft from the SSE, with combined energy hitting (42) and (48) respectively. It's still small, but the period is short at 5-6 seconds. The real killer is the wind. It's a constant onshore from the SSE or SE, which will just chop it up. It's a beach break set-up, so with that much onshore wind and small, short-period swell, it’s honestly looking more interesting for kite surfing than paddle surfing.
After that, it all fades back to nothing. From Wednesday the 16th right through to Saturday the 20th, we're back to 0.3 ft and 0.7 ft swells. The glassy conditions on the morning of Thursday the 17th and Saturday the 19th are a tease, but there's simply no water moving. The long-range part of the forecast is just blank. It's a proper dry spell for Octagon House.
When the swell is this small and the wind is on, it's a tough call. This area tends to have these blank runs, so it's not a total shock, but it's still a bummer.
Rusty, signing off.
