The Lowdown
Alright, folks, Rusty here. Let's have a look at what's cookin' for Fistral South over the next couple of weeks. I've got to be straight with you – this forecast is a bit of a mixed bag, and there's a lot of chop to sift through. We're not looking at any perfect, glassy gems in the immediate future, but there are a few windows where it could be worth a paddle if you're keen.
First up, the overall pattern is a bit of a struggle. We've got a persistent run of onshore and cross-onshore winds, which is going to make the surface lumpy and messy for a good stretch. The water is currently a balmy 66.6°, which is much warmer than we'd usually expect for this time of year – a real treat if you're brave enough to get in despite the conditions.
The first few days are a write-off for any real quality. Sunday the 16th and Monday the 17th have tiny swell, with heights around 1.3ft to 3.3ft, and the wind is on it, killing any chance of a clean wave. That combined energy is weak, reading just 23 to 104 (moderate on the 17th morning). It's just not worth the effort.
We see a bit more size rolling in from Tuesday the 18th, but the wind shifts to a cross-onshore, and the waves are lumpy and choppy. Swell heights around 3.6ft to 4.3ft, but with that wind, it's a messy affair. Energy climbs a bit, hitting 145 (moderate) on the Tuesday morning.
The middle of the week gets a bit bigger, but the wind is stronger. Wednesday the 19th sees 5.6ft to 6.6ft of swell from the WNW, but with a fresh 18.6 mph cross-onshore, it's going to be a real battle. The combined energy jumps to 303 and 437 (moderate), but the quality is poor.
Now, here's a glimmer. Thursday the 20th morning brings a 6.2ft swell from the WNW with a period of 9 seconds and a combined energy of 594 (moderate). The wind turns onshore from the NW in the afternoon, but that morning session might have some push. Still, it's a rain shower day, so you'll be dodging drops.
We get a bit of a break Friday the 21st and Saturday the 22nd, with the swell dropping right back down to 1.3ft to 3.3ft. The wind is still a factor, mostly cross or cross-on. The energy is weak, between 58 and 184. Not much to write home about.
Sunday the 23rd and Monday the 24th are about as flat as it gets. Swell heights drop to 0.3ft to 2.3ft, with very low energy readings (19 to 58). The wind is cross-shore, but there's just no swell to work with. It's a gap of a few days where you'd be better off staying on the beach.
We start to see a pulse of energy again from Wednesday the 26th. The morning has a 2.3ft swell from the W with a 9-second period, and the wind is on, so it might be clean but small. The energy is 137 (moderate). The afternoon picks up to 4.3ft from the W, but the wind goes cross-onshore.
Thursday the 27th morning has a 4.9ft swell from the W with a 7-second period and a combined energy of 228 (moderate). The wind is cross-onshore again, so expect chop.
Now, the big news is towards the end of the month. Friday the 28th is going to be a mess. A strong breeze of 24.9-28.0 mph from the W and WNW will create strong cross-onshore conditions and messy surf. Swell is around 5.2ft, but the energy is 240 (moderate). This is more of a kite-surfing day than a paddling one.
The standout, if you can call it that, is the weekend of the 29th and 30th of August. Saturday the 29th afternoon brings a solid 9.8ft swell from the W with a 9-second period and a combined energy of 1366 (strong to very strong). This is a big, powerful swell. However, the wind is a fresh 21.7 mph cross-onshore, so it's going to be a lumpy, messy beast. At this size (over 8.2ft), it's strictly for experts only, and the cross-onshore wind will make it a battle. The morning of the 29th is a 8.2ft swell from the SW with a 6-second period and an energy of 538 (moderate). Again, cross-onshore and lumpy.
Sunday the 30th is similar, with 6.2ft to 6.6ft swell and strong cross-onshore winds. The energy is around 431-441 (moderate). This is more of the

Information about the Fistral-South Surf forecast
The above surf forecast table for Fistral-South provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Fistral-South can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
