The Lowdown

Alright, grab a coffee and sit down, it's a bit of a grim picture. Honestly, for the next 16 days, Mawgan Porth (Cornwall) is going to be one to skip for most of the window. The water temp is about average for this time of year, nothing wild there.

We’ve got a massive run of poor conditions kicking off from Monday the 7th. For the first full week, right up to and including Monday the 14th, it’s just one messy, blown-out set after another. The wind is almost constantly cross-on or onshore from the west, and it's howling. A big day on Tuesday the 8th sees a fresh breeze at 22 mph making a 6 ft swell completely lumpy. There’s a heap of energy from that blow – the combined swell energy hits 1632 (moderate to strong energy) on Monday the 7th morning – but with that onshore wind, you’d be fighting a losing battle. Don’t even bother with the beach until at least the 15th.

Now, don’t get your hopes up too high, but there's a little glimmer on Tuesday the 15th. We get a 6 ft swell from the WNW, with a 12-second period, which is proper groundswell – that’s good shape. The combined energy is a healthy 872 (moderate wave energy). The wind is set to be light cross-on, which is far from perfect but might be okay if you’re desperate. The report calls it “marginal,” so it’s a gamble, but it's the only morning in the entire outlook that isn't a total write-off. Keep in mind the wave direction is 270° (WNW), which matches the optimum direction for this spot.

After that tiny window, the bad news comes back hard. Wednesday afternoon the 16th sees a 8 ft cross-on mess with a strong breeze, and by Thursday morning the 17th, we’re looking at a massive, dangerous 13 ft swell from the WNW with rain. That is a lot of energy (4046 – very strong wave energy), but it’s straight into the wind. That’s not a paddle-surfing day for anyone except experts, and even they’d be stupid to go out. For the rest of us, that setup screams kite-surfing, not surfing. The last few days of the period, like Sunday the 22nd, have a clean cross-offshore breeze from the NNE, but it’s too far out and the swell window is closing.

The long and short of it: there’s one morning on Tuesday the 15th that’s worth checking if you’re local and bored. Otherwise, this is a blank run. It’s a shame, but the north coast of Cornwall tends to have these stretches when the Atlantic is blowing strong from the west.

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 Mawgan Porth 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.
