The Lowdown
Alright, let’s check what Falmouth - Swanpool has cooking for the next couple of weeks.
Honestly, the surf is flat as a pancake to start and it stays that way for a good long while. The water’s at 18°, a little warmer than average for this time of year, so that’s nice for a swim but not much else.
Your first real shot at a wave doesn’t come until Monday afternoon, the 7th of September. That’s when we see a bump to a 2.2m swell out of the WSW with a 12-second period. That’s a proper groundswell with some serious grunt – the combined energy is a massive 1256. This is the only highlight, no question. With that size and power, it’s strictly for experienced surfers. The wind is a cross-off from the WNW at 25 km/h, keeping things clean. For the skilled crew, that’s your window.
Before that, Thursday the 3rd serves up a 1.7m to 1.6m swell from the WSW, but the wind is cross-off at 20 to 30 km/h. The notes say marginal conditions and dodgy tides, so it’s a pass. The energy is only moderate (339 and 313).
After Monday, it’s back downhill fast. Tuesday morning the 8th drops to 0.5m, and by the afternoon there’s nothing. Wednesday the 9th brings a puny 0.9m swell from the WSW with a 9-second period, but the energy is weak (108) and it’s a no-go.
Then we hit a long, dead stretch. From the 8th all the way to the end of the 16 days, it’s mostly flat or tiny 0.1m dribbles. The wind is often clean or offshore, but without any swell, it’s a total bust. Absolutely nothing worth getting wet for after that Monday pulse.
So here’s the deal: if you’re an expert, circle Monday the 7th of September. That’s your only real chance. For everyone else, leave the board at home.
