The Lowdown
Alright mates, Rusty here. Let’s break down what’s happening at Poldhu Cove.
The first real opportunity is Saturday morning, the 5th of September. We’ve got a 6ft west swell with a long 12-second period, and the wind is absolutely glassy. That means clean, lined-up waves. The water is about 64°F, slightly warmer than average. The combined energy is moderate at 641. This is the highlight, no question. Just remember, this spot is inconsistent, so it’s a bit of a gamble, but when it works, it’s magic.
That same Saturday afternoon, the wind swings south and goes cross-on, messing up the surface, so don’t bother.
From Sunday the 6th all the way through, it’s a rough ride. Monday the 7th of September sees a big 8ft west-southwest swell with a 13-second period, pushing combined energy to 1875 – that’s strong. But with a cross-onshore wind at 25 km/h (16 mph), it’s lumpy and choppy. That size is for experts only, and with the wind, it’s more of a kitesurfing day than a paddle session.
The rest of the week and into the next is plagued by onshore winds and messy conditions. By the 15th of September, we get some cleaner cross-offshore winds, but the swell is under 3ft with weak energy, so nothing to write home about.
The very end, on the 18th and 19th of September, offers tiny 2ft and 1ft waves with glassy conditions on the morning of the 18th. That’s barely enough for a foamie.
So, your window is Saturday morning, the 5th of September. After that, it’s a long stretch of poor, wind-blown surf. Hang in there.
Rusty.

A general guide to surfing at Poldhu Cove 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 Poldhu Cove 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.
