The Lowdown
Alright, grab a coffee and settle in, because the next couple of weeks are looking pretty flat for us here in the South West. I’m not gonna sugarcoat it, we’ve got a real dry spell on our hands.
We’re looking at Whitsand Bay and Tregantle, and the water is hanging in at about 66°F, which is a touch warmer than you’d expect for this time of year. Feels nice if you’re having a paddle, but that’s about all the action you’ll be getting for a while.
The outlook starts with a real dud. Tuesday the 11th through to the morning of Tuesday the 18th is a full week of nothing but poor surf. We’re looking at tiny, weak swells, mostly under 2ft, with periods barely scraping 10 seconds. The combined energy is pitiful, hovering around single digits and low double digits. The wind is all over the shop, mostly cross or cross-off, but it doesn’t matter because there’s just no wave to work with. It’s a total write-off.
We finally see a little flicker of life on the morning of Thursday the 20th of August. The swell bumps up to 3ft from the WSW with a 12-second period, giving us a combined energy of 262 – that’s moderate, at least. The wind is a light cross-shore from the NW, which is okay. But the forecast calls it “marginal,” and I’d have to agree. It’s not going to be pretty, but it’s the first real sign of life in over a week.
Then, the standout of the whole forecast window is the Friday the 21st of August. The morning starts with a glassy 2ft WSW swell, and the afternoon cleans up even more with a 3ft swell from the same direction. The periods are a solid 11 seconds, and the energy is moderate. The wind is dead calm, glassing it right off. For a spot like Whitsand that’s exposed to the SW, this is as good as it’s going to get in this flat spell. It’s small, sure, but it’ll be clean and rideable. Don’t expect a world-class session, but it’s the only time you’ll want to be in the water.
After that, it’s back to the doldrums. Saturday the 22nd gets messy again with onshore winds, and the rest of the month into the 26th is a mix of small, weak swell and strong, lumpy winds. The 26th of August morning sees a pulse of 4ft from the west with 263 energy, but it’s pinned under a fresh onshore breeze from the SW, making it a total mess. This spot is a beach and reef setup, and with that much wind on it, it’s looking more like a kiteboarding session than a surfing one.
So, to sum it up: the next week is a zero. Thursday the 20th is a maybe, but Friday the 21st of August is your best bet. Get on it if you can, because the forecast is pretty grim after that.
