The Lowdown
Alright, surfers, it’s Rusty here. Let’s be straight with you – this forecast for the Falmouth – Swanpool area is a tough one. We’re looking at a 16-day window that’s almost entirely devoid of any real surf. It’s a long, flat spell, and I mean *long*. We’ve got a solid two weeks-plus of nothing on the cards for a proper wave.
The only tiny blip on the radar, and I use that term loosely, arrives early next week. On Tuesday the 12th, we finally see a pulse of energy. It’s not huge – a summary swell of around 2.6ft to 3ft – but the combined wave energy does bump up into the moderate range (206-209). That’s the most we’re going to see. The period is around 9-10 seconds, so it’s not a groundswell, but it’s the best of a bad bunch. The problem is, the wind is on it. The morning is cross-onshore from the ENE, which will make it lumpy and uninviting.
Wednesday the 13th still has a bit of that energy (358), with the swell from the WSW at 4ft and a longer 11-second period. The wind is a cross-offshore from the N, which will help keep it clean. This is the standout, but only because everything else is so flat. Given it's a beginner spot, 4ft is at the top end of what’s comfortable, and the long period could make it a bit shifty for the less experienced. Still, it’s the only time we see any real potential. After that, the plug gets pulled, and we’re back to dribble for the rest of the forecast, with winds often fresh and onshore from the east.
To add a bit of context, the water temp is about 65.8°F, which is 3.2°F warmer than normal for this time of year – a touch of extra warmth for the long paddles you’ll be doing looking for waves that aren’t there.
Honestly, if you’ve got a kite, a lot of those days on the 21st through the 23rd look more interesting for you than us paddle surfers, with fresh cross-onshore winds and shin-high slop. It’s a bleak outlook, folks. Hang tight, this one’s a write-off.
