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.

Information about the Falmouth - Swanpool Surf forecast
The above surf forecast table for Falmouth - Swanpool provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Falmouth - Swanpool 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 Falmouth - Swanpool 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.
