The Lowdown
Alright folks, Rusty here. Let's have a proper look at what’s coming up for Poldhu Cove over the next couple of weeks.
Gotta be straight with you – the start of this forecast run is a bit of a write-off. Wednesday morning kicks us off with some 5ft swell from the WNW at a 9-second interval, and the combined wave energy is sitting at a moderate 456 (combined energy of all swells directed here). But that NW wind is cross-offshore, which keeps things looking clean. The water’s sitting at 65°, which is a touch warmer than normal for this time of year. The trouble is, the surf quality comments aren't great, and there are tide issues to contend with. By Wednesday afternoon, it drops off. Thursday’s a total loss with strong onshore winds and messy, blown-out conditions. Thursday afternoon sees the swell jump to 6ft but with a short 7-second period and gale-force onshore winds – it’s a complete washout, not for paddling.
Friday the 11th of September is where things start to look interesting. Friday morning, we’ve got a clean 5ft swell from the W, 9-second period, and a light NNW cross-offshore breeze. The combined energy is 440 (combined energy of all swells directed here). This is clean, shoulder-high surf with some shape, and the light wind will keep the surface glassy. This is your best bet in the whole outlook – the standout session. Poldhu Cove is a fairly exposed SW-facing spot, so that W swell wraps in nicely. Keep in mind it’s an inconsistent break, so you might have to wait for sets, but when they come, it’ll be worth it. The crowd factor is "sometimes," so you might have company, but it shouldn't be a zoo.
Saturday and Sunday see the swell size staying in the 3ft to 6ft range, but the wind swings onshore and cross-onshore, introducing chop and making things messy. Sunday morning has a cleaner cross-shore wind and a longer 10-second period, but it’s rated as marginal. Not the best.
The following week, from Monday the 14th through to the 24th, is mostly poor. There are flashes of clean conditions – like Wednesday the 16th morning with a cross-off breeze, and Sunday the 20th with a light cross-off – but the swell is small, mostly under 4ft, and the energy is weak. The standout in this second week is Monday the 21st of September morning: glassy conditions with a 3ft W swell, 11-second period, and combined energy of 236 (combined energy of all swells directed here). That’s clean but tiny – a longboard or funboard kind of morning. By the end of the run, we’re down to knee-high dribble with no energy.
Overall, if you want the best surf, paddling out Friday morning the 11th is your window. The rest is a waiting game. It’s a bit of a quiet spell for Poldhu, but that’s how it goes sometimes – forecasts can change, and it tends not to stay poor for long.
