The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Octagon House area.
Right off the bat, I gotta be straight with you – this 16-day window is a real flat spell. We're looking at a long stretch of nothing doing. The first record we've got shows Friday, July 31st, but honestly, it's a write-off. The swell is tiny, coming in at a weak 2ft from the south with a snappy 5-second period, and the combined energy is a measly (20). The wind is messy, and the report is calling it poor surf. That's the story all the way through.
In fact, we're looking at a solid gap of no surf worth mentioning right through to at least Saturday, August 15th. Every single day in that window is tagged as "poor surf conditions". The swell stays small, generally between 1.0ft and 3ft, and the period is short – mostly 4 to 6 seconds. That's windswell, not groundswell, so the waves will be weak and lack any real punch. The wind is almost always cross or cross-onshore, adding chop to the mix. The water temp is a touch warmer than normal for this time of year, sitting at around 87°F, but that's about the only thing going for it.
The little bump we see around Monday, August 10th, with the swell hitting 3ft and the energy climbing to (58), is still just short-period windswell and the wind is on it. It's not going to break clean. If you're a beginner, the heights are safe, but the conditions are just too poor for any kind of fun session.
For the more experienced crew, there's nothing here that's going to get the heart rate up. The combination of small swell, short period, and onshore winds means we're looking at a blank run. It's a bit of a bummer, but it's the kind of flat spell that happens in this area. The forecasts can change, so keep an eye on it, but don't hold your breath for this one.
Rusty.
