The Lowdown
Alright crew, Rusty here. We’ve looked at the Bossiney Haven stretch, and I’m not gonna sugarcoat it – it’s a rough patch. The next couple of weeks are looking pretty grim, so don’t get your hopes up.
We’re starting off on Tuesday the 4th of August with a flat, clean ocean, but there’s zero swell energy. That sets the scene. Wednesday the 5th brings a bump from the west at 6ft, but it’s a short-period 7-second windswell with a fresh cross-breeze, turning it into a lumpy, choppy mess. The energy is moderate at 303, but the wind ruins it. Thursday and Friday are even smaller, with a bit of glass on Friday morning the 7th, but with only 1.0ft of west swell, you’re lookin’ at ankle-biters. The water is at 65°, which is a touch warmer than normal for this time of year.
The whole first week is a total wipeout. There’s a tiny glimmer on Wednesday the 12th of August with clean conditions from the east-southeast wind, but that west swell is only 2ft to 2ft. The energy is weak (72 and 92), so it’s a long paddle for a knee-high wave.
The only real standout, if you can even call it that, is on Saturday the 15th of August. Bossiney Haven gets a pulse of 6ft west-northwest swell with a 9-second period, pushing the energy up to a strong 446. The morning has a light cross-onshore breeze. It’s labelled as a “marginal” call, which is the best we’ve got. The swell is over 5ft, so it’s getting a bit much for beginners, and the period is short enough to keep it from being a classic. It’s the only one with even a whisper of a chance, but don’t expect perfection.
After that, the surf drops back down. There’s a stormy day on Tuesday the 18th of August with a 6ft west swell and a fresh cross-breeze, but the energy is howling at 575. With that strong onshore wind, this setup looks more interesting for kite surfing than paddle surfing.
Bottom line: it’s a lean 16-day window. The surf is small, the wind is mostly wrong, and there’s a real gap of no fun from the 4th all the way to the 15th. Forecaster’s note: when it’s this flat and clean, the forecasts can change, but for now, leave the board in the shed.
Rusty.
