The Lowdown
Alright, surf's up... or not quite yet. Let's be real with you.
Right now, for the next week and a half, it's flat as a millpond out at Falmouth - Swanpool. We're talking ankle-biters at best; those 0.3ft to 1ft sloppy little waves aren't going to get anyone out of bed. The swell energy is weak, sitting in the single digits and teens, like 7, 11, or 29. It's just not doing anything. There's some clean windows with the offshore and cross-offshore winds, especially around the 22nd, but with no swell behind it, it's just a pretty, glassy ocean.
Honestly, the first real sign of life doesn't show up until Wednesday the 26th. Even then, it's a bit of a tease. We get a jump in energy to 325 with a 5ft swell from the WSW, but the wind is only light cross-offshore. It's surfable, but it's not the day you've been waiting for.
Now, listen up, because this is the one you've been waiting for. Friday, the 28th of August, is the standout. This is a big one. We're looking at a solid 18ft of groundswell from the WSW with a long 13-second period. The energy is enormous – a reading of 10021, which is just pumping. The wind is howling offshore from the NNE at 28 mph, which is going to keep it as clean as it gets for a wave that size. This is not for the faint of heart. At this size, it's strictly for experts. For everyone else, it's a spectator sport. This is one of those days where it might be more interesting to watch from the shore than to be out there. The swell is just too big for this break. It's a day for the heavy hitters only.
So yeah, it's a long, flat stretch for the most part. But that one day at the end of the month is looking proper.
