The Lowdown
Alright, grab a coffee, let's have a yarn about the next couple of weeks here at Capo Mannu Point. Straight up, it’s a frustrating picture. We’ve got a solid block of nothing worth paddling out for from today, 17 August, all the way through to Sunday the 25th. The swell window is basically shut. You’ll see tiny bumps (0.3 ft to 2 ft) and onshore or weak cross-off winds most days. It’s a classic August flat spell for this exposed reef, so don’t get your hopes up. The water temp is sitting at 84°F, which is 5°F warmer than usual for this time of year – that’s notably warm, so at least the waiting will be comfortable.
Monday the 19th afternoon gives us a glimmer of hope, with a small 4 ft NW swell (7 seconds) and light cross-off wind. It’s surfable but very ordinary, and the combined energy is weak (103). Nothing to write home about.
The real standout, and I mean the *only* true standout in this whole 16-day window, shows its face on Sunday the 30th of August. We get a pulse of NW groundswell. The morning sees 5 ft at a short 7-second period, with light cross-shore wind, and combined energy climbing to 294 (moderate). But the afternoon is where it’s at: 7 ft of NW swell, period stretching out to 8 seconds, combined energy jumping up to 569 (moderate-strong), and clean, cross-off wind from the WNW. This is the pick of the fortnight.
For a reef point like Capo Mannu, that longer-period energy from the NW – which matches the optimum swell direction – will set up some proper lines. Just a heads up, the swell is over 5 ft, so it’s not for beginners, and with the occasional crowd factor here, you’ll want to be on your game. It’s still over a week away, so treat this as a promising lead, but the setup looks very, very good for advanced crew.
After that, it drops off again. The 31st and 1st of September are back to weak, ordinary conditions with onshore winds and fading swell. A true one-day window in a long, flat gap.
Keep an eye on that 30th – it’s our shot.
