The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got coming up.
Honestly, the next two weeks at Fistral-South are a real mixed bag, and if I’m being straight with you, there’s not much to get excited about for a long stretch. The forecast is pretty grim for the first ten days or so, with only a small window of hope right at the very end.
We kick off on Saturday the 15th, but don’t bother waxing up. It’s cross-on and lumpy with a 19 mph breeze, and the swell is a weak, short-period 3 ft from the west. The water temp is about average for this time of year, nothing special. This poor run just keeps rolling through Sunday, Monday, and Tuesday – all cross-onshore or onshore wind, tiny weak swell, and a lot of chop. The combined energy is barely a whisper, mostly under 100 (42 to 133 range), so you’re looking at weak, gutless waves.
There’s a seven-day gap from the 15th to the 22nd where you'd be best off staying home. Wednesday the 19th sees a bit more size (4 ft) but it’s still onshore and messy, and the energy only gets to a weak-to-moderate 182. By Thursday the 20th, the swell bumps up to 5 ft from the WNW, combined energy hits 323 (moderate), but the wind is a cross-on fresh breeze, so it’s lumpy. The wave quality is still poor. Friday the 21st and Saturday the 22nd are no better – still cross-on or cross-shore with moderate breezes and weak energy.
Now, hold on. There’s a real glimmer on Tuesday the 25th. Monday the 24th shows the swell building to 5-6 ft from the west, with energy climbing to 326 and then 466 by the afternoon (strong energy). But the wind is still cross-on or onshore. The change comes Tuesday morning, 25th of August. We’ve got a 5 ft west swell, with a light 6 mph cross-offshore breeze from the SSW. That’s clean. Actually clean. The combined energy is a solid 363 (strong). This is the standout of the whole run. The period is 8 seconds, shorter period, so it won’t be perfect, but with that offshore wind, Fistral-South should have some proper, rideable walls. It’s an intermediate break, consistent, fairly exposed, and it likes a WSW swell – this west swell is close enough. Crowds are often here, so expect company.
After that Tuesday morning window, it drops off again. Tuesday afternoon goes cross-shore and a bit messy, and Wednesday the 26th gets blown out by a 22-25 mph fresh to strong breeze. The rest of the week into the 30th is mostly onshore or cross, with messy conditions and small swell. That Sunday the 30th shows a 6 ft swell from the west with a moderate cross-onshore – still choppy.
So, the one to really circle is that Tuesday the 25th morning. It’s not a giant day, but it’s the only time we get clean, lined-up waves. For the rest, it’s a whole lot of waiting. Fistral can be a kite spot when it’s windy and messy, and late August with those strong breezes, you might see more kites than surfboards out there. Stay patient, and keep an eye on that Tuesday session.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Fistral-South may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
