The Lowdown
Alright, folks, Rusty here with your Falmouth - Swanpool surf outlook.
Straight up, this is a grim sixteen-day stretch. We’re looking at a long, painful gap with virtually nothing to get excited about. The water is sitting at 66° — that’s a touch warmer than usual for this time of year, so the swim trunks are fine, but you won't be needing a wetsuit for any real surf action.
From now all the way through to the end of August, the story is the same: tiny, weak swells and poor conditions. The combined energy is barely registering above 20 for most of it, just a weak pulse of SSW windswell that’s doing nothing. We get a bit of a spike in combined energy on the 22nd, hitting 169, but that’s a 4ft E swell at a short, chunky 6 seconds — mixed with an onshore breeze, it’ll be a choppy, un-ridable mess. Even the glassy morning on the 24th with 0.7ft of swell will leave you floating.
The first real glimmer of hope doesn’t come until Wednesday the 26th. The morning sees a 4ft WSW swell with an 8-second period, and the wind is offshore from the NW—clean conditions with a combined energy of 221. This is surfable, but it’s just ordinary. The afternoon picks up slightly to 4ft and the energy jumps to 319, but the wind swings cross-offshore. It’s your best bet in the first week, but don’t expect much.
After that, we get another dead period until the very end of the window. Mark your calendars for Tuesday the 1st of September. There’s a serious pulse of energy coming through in the morning: a 10ft WSW swell, 8-second period, with a fresh NNW offshore wind. The combined energy is a strong 957. This is serious size for Swanpool. With that heavy, short-period swell and strong offshore wind, this is strictly for experienced surfers only. It’ll be powerful, clean, and hollow, but a beginner will get worked. It’s a standout, but it’s a long way off and everything is uncertain that far out.
So, the bottom line: a whole lot of nothing until the 26th, and then one serious, expert-only shot on the 1st of September. Keep an eye on that for sure.
