The Lowdown
Alright folks, Rusty here. Let's have a look at the 16-day outlook for our little corner of the coast.
Right off the bat, it's a grim start. We're looking at a solid week of nothing but frustration. From Monday the 24th of August all the way through to Tuesday the 1st of September, the surf is just a no-go. The wind is all wrong, mostly strong onshore or cross-off, and the energy is pathetic. We're talking about a combined swell energy of just 37 on Monday morning, which is basically flat. It's a write-off.
Then, on Wednesday the 2nd of September, things finally perk up. The wind swings around to a light cross-off from the north-northeast at 9 mph, and the sea glass off. We get a solid 6 ft swell from the west at 8 seconds. The combined energy jumps to 483 (moderate), and the conditions are clean. This is our first real standout. The water is sitting at a touch warmer than normal for this time of year, about 65°F with a 2°F anomaly.
Thursday the 3rd of September will still offer some clean waves, but it's a step down. The swell drops to 4 ft from the west, with a combined energy of just 190 (weak). The morning is the best bet with light north winds, but it's very ordinary. By the afternoon, the wind swings onshore and it's back to poor conditions.
And that's it. After that brief window, we're back into the doldrums. From Friday the 4th of September right through to Monday the 8th, it's all onshore winds, messy chop, and poor quality. The swell gets bigger, but it's blown out. On the 8th, we see a massive 13 ft groundswell from the west-southwest with a very long period of 16 seconds and a combined energy of 8865 – that's a huge amount of power. But the wind is onshore, and for a break like Poldhu Cove, that's just not going to be working. It's a stormy mess.
So, the one and only true standout is Wednesday morning, the 2nd of September. That's your window. It's not a world-beater, but after a week of nothing, a clean 6 ft wave with a light offshore breeze is a proper gift. Don't sleep on it. The lack of consistency is a worry, but for now, that's the best we've got.

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. 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.
