The Lowdown

Right then, grab a cuppa, 'cause we've got a 16-day window to look at for Mawgan Porth. This is a river mouth break, fairly exposed to the swell, and it's a beginner-friendly spot. The water temp is about average for this time of year, nothing unusual there.

Honestly, the outlook is a bit of a tough one. The first surfable waves don't show up until Tuesday morning, the 21st of July. Before that, Monday the 20th is a total write-off with tiny, weak swell and poor conditions. So we've got a quiet start to the week.

Tuesday morning, the 21st, you'll see some small 3ft swell from the NNW, but the period is a short 5 seconds, so it's not going to have much push. The wind is a cross-offshore breeze, which will keep it clean, but the combined energy is only 78, so it's weak. It's surfable, but very ordinary. The afternoon gets choppier, so forget that. Wednesday the 22nd is a similar story, a bit more size at 4ft from the north, but onshore winds mess it up.

Thursday the 23rd of July might be your best bet early on. The morning has glassy conditions with an ESE wind, and a 3ft, 6-second swell from the north. The energy is weak at 63, but with it being a river mouth, that longer-period swell (6 seconds is still short, but it's the best of the bunch) can occasionally line up a bit. It's a long shot, but for a beginner, it's about as clean as it gets in this run.

The rest of the week and into the weekend is a write-off. The swell bumps up, but the wind is all over the place, mostly onshore or cross-onshore, creating choppy, lumpy conditions. The surf will be poor, and the energy gets higher, hitting 439 on Sunday the 26th with 7ft swell, but it's a mess. That kind of size and energy with a 7-second period and onshore wind is more of a kite-surfing setup than a paddle-friendly one.

The second week (from the 28th of July onwards) doesn't offer much hope. The swell sticks around, but the wind is consistently poor, with the wrong direction. The energy readings are moderate, up to 163 on the 30th, but the conditions are always described as poor. There's no standout day in that second week.

So, to be honest, the only real standout is a slim one: Thursday morning, the 23rd of July. The tiny, glassy surf might be enough for a quiet, clean session if you're a beginner or just want to get wet. Crowds are possible at Mawgan Porth, so you might have some company. For everyone else, keep an eye on the forecasts, 'cause this stretch looks pretty bleak.
