The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s brewing for the next couple of weeks.
Honestly, it’s a tough stretch ahead. We’re looking at a long, quiet run with hardly anything worth paddling out for. The water is sitting at 64°, which is a touch warmer than normal for this time of year, so at least the sting won’t be as sharp when you’re sitting there waiting for a wave that’s not coming.
The first real chance of anything comes on Saturday, the 29th of August, at Broadhaven South. That morning, we’ve got a stiff 16 mph offshore wind from the west, keeping the surface clean. Swell is running 4 ft from the southwest, with a period of 8 seconds. The combined energy is moderate at (435). It’s still a marginal call, though—tide conditions might muck it up. This spot is a sheltered one, and it’s inconsistent, so don’t expect a wave every minute. The offshore wind is a major positive here, giving you clean lines, but for a break that only works now and then, this is about as good as it gets in this quiet spell.
Sunday the 30th sees a bump in size, with swell pushing 6 ft from the west-southwest, but it’s a cross-shore wind by afternoon and the energy is still solid at (402). The period’s still short at 8 seconds, so it’ll be a bit crumbly and messy. Monday the 31st turns on a bit more size, hitting 7 ft, but with the same cross-shore wind and a risk of thunderstorms, it’s not going to be a classic. That 7 ft mark is a bit heavy for beginners, and the cross-shore chop will make it tricky.
The standout, if you can call it that, is the Saturday morning session. The combination of clean offshore wind and a moderate 4 ft southwest swell gives you the best shot at a few clean, lined-up waves. For a rare spot like Broadhaven South, you take what you can get.
After that, the first week of September drops off a cliff. Thursday the 3rd has a tiny 2 ft swell with offshore wind, but it’s barely a ripple. The next Saturday, the 5th, is the same story—small, clean, but tiny. There’s a big gap of poor conditions from the 1st through the 5th.
So, it’s a lean period. The best of it is that Saturday morning, 29th August. Don’t get your hopes up too high, but if you’re keen, that’s the window.
Stay safe out there.
Rusty.
