The Lowdown

Alright, surf’s up… or at least, it’s gonna try to be. Let’s talk about the next couple of weeks at Mawgan Porth. To be straight with you, it’s looking like a lean stretch. The finder’s not throwing up any proper gems, so we’re hunting for the least-average windows, not the standouts.

For the first week, it’s mostly small and messy. The energy is just weak. On Tuesday the 11th, we’ve got a tiny 0.7ft swell with a 13-second period, but the 25 km/h cross-offshore wind is going to be fighting it, and the overall energy is a paltry 31. It’s clean, but there’s nothing to ride. Wednesday the 12th offers a touch more, pushing 3ft from the west with a 10-second period. The morning has a light 5 km/h offshore breeze, and the energy reads 125. It’s surfable, just very ordinary. Thursday the 13th sees a bump in size to 4-4ft, but the wind swings cross and cross-on, making it choppy and poor. The energy jumps to 267, but it’s not going to be pretty. We’re looking at a few days of nothing good after that. The swell drops back under 3ft, the wind stays messy, and the energy falls to under 100 for a lot of it. There is a window on Tuesday the 19th, where a longer 11-second period west swell shows up, but it’s accompanied by onshore winds and the conditions are just not there. It’s a blank stretch until roughly the 24th.

Now, looking further out, there are a couple of pulses of proper energy on the horizon, but they look grim for us. On Monday the 24th, the afternoon sees a jump to 7ft from the west with a solid energy reading of 521. But it’s coming with a strong 35 km/h cross-shore wind, churning it into a lumpy mess. That’s not a surf forecast, that’s a kite-surf forecast. The same goes for Wednesday the 26th, where we see the biggest swell of the period at 8ft, an energy reading of 664, but with onshore winds and light rain. It’s going to be big, but it’s going to be blown out and ugly. This is expert-only territory if anyone is silly enough to try it.

The water is running a touch warmer than normal, about 4° above the average, so it’s a bit more pleasant than you’d expect. But honestly, with the lack of quality surf, you’re better off keeping the board in the car for most of this. The first week is a write-off, and the second week’s size comes with too much wind. Keep an eye on it, but manage your expectations.

A general guide to surfing at Mawgan Porth 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 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.
