Capo Mannu Point Surf Forecast and Surf Report

G’day, Rusty here. Look, the 16-day window for this region kicks off with a bit of a flat spell, but if you’re patient, there’s a ripper pulse of big groundswell coming in the second week that’s worth putting a pin in.

The early part of the outlook is pretty grim. From Thursday the 10th through to the end of the third week of September, it’s mostly small, weak junk. Thursday the 10th morning has a short-period 6ft swell from the NW, but it’s pushed by a strong 25 km/h NNW wind – just messy. The water’s sitting at 83°F which is much warmer than normal for this time of year, a solid 7°F above average. That early window is a write-off.

From Friday the 11th, it drops away fast. You’re looking at waist-high or smaller stuff for days, with combined energy figures barely creeping into double digits (36, 21, 15). A lot of clean mornings, but no power behind it. There’s a stretch from around the 13th to the 20th where there’s effectively no surf to speak of – just flat or ankle-slop. That’s nearly a week of nothing worthwhile.

Now, here’s where it gets interesting. Come Monday the 21st of September, the whole game changes. A solid pulse of NW groundswell rolls in, with the morning showing 13ft at 10 seconds and the combined energy hitting a massive 3105 – strong wave energy. Wind is light and offshore from the NNE, so conditions will be clean. This is big, powerful swell – definitely for experienced crew only, as it’s well over 8ft. The optimum swell direction is SW and this is coming from NW, but the exposure here handles it.

Monday afternoon keeps pumping at 16ft from the NW, period stretching to 11 seconds, but the wind swings NW at 30 km/h, making it cross-off and a bit gnarly. Combined energy sits at 6616 – very strong. Only for experts.

Tuesday the 22nd morning still has a solid 12ft WNW groundswell, period at 11 seconds, and clean conditions with a light NNE breeze. Energy is 3389 – still properly strong. Again, experts only. The afternoon gets messy with strong cross-off wind.

By Wednesday the 23rd morning, it settles to a more manageable 6ft from the WNW (9 seconds) and lighter NE winds, giving clean conditions. Combined energy is moderate at 614. Still a solid session for strong intermediates.

Thursday the 24th morning has a cleaner 5ft WNW swell (8 seconds) with glassy conditions – just a slight air from ENE. Energy at 315. That’s a good, fun morning for most.

The standout in the whole window is Monday the 21st of September at Capo Mannu Point (Capo-Mannu), a reef break that’s fairly consistent and takes an exposed SW swell. You’ll get a solid 13ft groundswell from the NW, clean with light offshore wind – raw power, long-period energy, and faces that will really stand up on this reef. It’s strictly for advanced surfers. Don’t expect company mid-week, but crowds are possible on the weekend.

So to wrap it: the first 10 days are a dry spell, but that last week delivers some serious juice. Keep your eye on that big Monday the 21st.

Rusty.
