The Lowdown
Alright folks, Rusty here. Let's have a look at what Middles/Generals has in store for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough one. The whole 16-day window is looking pretty grim. We’ve got a lot of wind and not much in the way of quality surf. The water temp is sitting around 80°, which is about normal for this time of year, so at least you won't be freezing your nuts off waiting for a wave that never comes.
We start off Wednesday the 5th with a bit of swell from the ENE, around 4ft, but it's a short-period 9-second thing and the wind is howling cross-shore from the NE at 16 mph. The combined energy is moderate at 379, but the conditions are just poor. Thursday the 6th drops right off to 1ft, and it stays tiny through to Friday the 7th, with that same relentless cross-shore wind. The swell direction swings around to the SSW with a long 14-second period, but there's just no size to work with.
Saturday the 8th sees a jump to 5ft, then 6ft in the afternoon, all from the ENE but with a weak 7-second period. The wind is still a fresh cross-shore at 22 mph, and the energy is getting up there (360 by Saturday arvo), but it's gonna be a messy, chopped-up mess. This trend continues through Sunday the 9th, with the swell hitting 6ft and a slightly better 8-second period, and energy climbing to 675. Still, the wind is just ruining it.
Then we get a bit of a lull early next week, with the swell dropping back to 2ft to 3ft on Monday and Tuesday the 10th and 11th, with long-period SSW groundswell but zero power. The wind doesn't let up. Wednesday the 12th brings a bit more hope with a 3ft S swell and a very long 18-second period, and the energy is strong at 975. But again, the cross-shore wind from the ENE at 19-22 mph is going to put a chop on it.
The real size shows up from Friday the 14th onwards. We’re looking at 8ft to 8ft of ENE swell, with a short 8-second period, and the wind is a strong breeze at 25-28 mph. The combined energy is over 1000 (1056 on Friday morning), which is strong, but that’s not the kind of energy you want for a good wave. This is big, messy, windblown slop. At that size, it’s pushing into expert-only territory, and with the wind and short period, it’s really only going to be interesting for the kite surfers out there.
This solid, choppy, onshore-looking mess carries right through to the end of the forecast on Thursday the 20th, with the swell staying around 6ft to 7ft and the wind staying fresh to strong from the ENE. There is simply no standout session in this entire window. The best you could hope for is a quick paddle out on the 12th or 13th when the S swell has a bit of energy, but even then the wind is going to be a factor.
Honestly, this is a blank run. The forecast is telling us it’s going to be poor for the whole 16 days. It’s one of those stretches where you might as well wax the board up for the next one. Forecasts can change, but as it stands, I’d be finding something else to do.
Rusty.
