The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for us.
To be straight with you, the 16-day window is looking pretty grim for a proper surf. There’s a long stretch of flat to tiny, poor-quality waves that’s going to be tough to sit through. The first real chance of anything worth paddling out for doesn't show up until Thursday the 24th of September, and even then, it's only just surfable. Before that, we're looking at a solid two-week gap where the conditions are just not cooperating.
When things finally try to turn around on the 24th, Coastguard Beach might have a tiny spark. Thursday morning we could see a 3ft wave coming from the ENE with a period of 8 seconds. The wind will be offshore from the WNW at 16 mph, which will clean it up nicely, and the water temp is sitting at about 66°F, which is pretty normal for this time of year. The combined swell energy is a modest 133, so it's not a powerhouse, but at least there's a little bit of push. The wave comment does say "surfable waves but very ordinary conditions," and the rating is low, so don't get your hopes up for anything epic. The ENE swell direction is a direct hit for this spot, so it’s the best of a bad bunch. If you're desperate for a paddle, that's your window, but it's more for the beginners looking for a gentle intro.
Otherwise, through the rest of the period, the swell is either tiny, the wind is all over the place, or both. We see some moderate combined energy values like 125 and 175 pop up on the 22nd and 23rd, but the wind is cross-onshore and onshore, making a mess of it. The 4ft swell on the 22nd afternoon has a combined energy of 125, which is decent, but the light cross-onshore wind won't help the shape much.
In short, it's a pretty bleak outlook for the next two weeks. Don't expect any standouts. The only thing worth mentioning is that morning on the 24th, but it’s far from a sure thing. I’d keep an eye on the forecast, because things can change, but for now, it’s looking like a good time to wax your board and wait.
