Mawgan Porth Surf Forecast and Surf Report

Alright folks, it’s Rusty here. Let’s have a proper look at the charts for our little corner of the world. Straight up, I’ve got to be honest with you – this is a pretty grim stretch ahead. The next 16 days are looking tough, with a whole lot of wind and messy conditions, and barely a single standout session to get excited about. We’ve got a big gap at the start with no real surf to speak of, and it’s a long wait before anything even remotely interesting shows up.

The first real chance to get wet is Monday morning, 24 August. We’re looking at Mawgan Porth, a river mouth break that’s fairly exposed to the swell. The water temp is sitting at 64.9°, which feels a touch warmer than normal for this time of year. But the story here is the wind – a fresh 19 mph easterly blowing straight offshore. That’s clean, real clean. Too bad there’s barely any swell to work with, just a tiny 0.7 ft from the WSW with a period of 9 seconds. The combined energy is a measly 17 (weak), and the report says it’s poor surf. You’d be lucky to get a ride.

Tuesday morning, 25 August, things improve slightly. The swell picks up to 1.6 ft from the west, with a gentle 9 mph offshore breeze from the east. The period is 10 seconds, and the energy bumps up to 71 (still weak). Technically surfable, but it’s very ordinary. Tuesday afternoon gets a bit more energy (95) but the wind swings onshore and the quality drops right off.

Wednesday, 26 August, is a write-off. The swell is small and weak, and the wind is messy. Thursday morning, 27 August, sees a little more size – 2.6 ft from the SW – but the period is a short 7 seconds, so the waves will be weak and lumpy. The energy is 84 (still weak). It’s clean, but it’s not going to get your heart racing.

Friday morning, 28 August, is probably the best option in the first week. A 3.3 ft south-west swell with a 10-second period, and a dead calm, 3 mph offshore breeze. The sea will be glassy. The energy is 130 (moderate). It’s not a classic, but it’s the cleanest windows we have. However, the afternoon turns into a choppy, onshore mess.

Saturday, 29 August, and Sunday, 30 August, are blown out. Sunday afternoon gets a 5.2 ft swell with a 7-second period, and a strong 25 mph cross-onshore wind. The energy is 240 (moderate), but the quality is terrible. This is more of a kite-surfing setup than a paddle one.

Now, we enter a period of building swell, but it’s accompanied by terrible wind. Monday, 31 August, sees a 9.8 ft swell from the west with a 10-second period, and the energy is a massive 2206 (very strong). But the wind is a strong 25 mph onshore. This is big, powerful, and completely unsurfable. This trend continues for the next few days. Tuesday, 1 September, is cross-on and messy. Wednesday, 2 September, has a 5.6 ft swell with a short 7-second period, but the wind is still cross-on. The energy is 305 (moderate).

Friday, 4 September, is a bit of a tease. The swell is 5.2 ft to 5.6 ft from the west, with a much nicer 11-second period (groundswell). The energy is 596 to 671 (strong). But the wind is a firm 12-16 mph onshore, so it’s going to be a bumpy, lumpy mess. Not for the faint-hearted.

Saturday, 5 September, is more of the same – strong groundswell (12-second period, 933 energy) but with 19-22 mph cross-onshore winds. This is when you take the camera, not the board.

The real monster shows up on Monday, 7 September. A 14.8 ft west swell with a 17-second period – that’s a very long period groundswell, carrying insane energy (10556!). This is a proper big-wave event. The problem? A 15-19 mph onshore wind. This is massive, powerful, and dangerous. Unless you’re a tow-in expert, stay well clear. The river mouth at Mawgan Porth will be a washing machine, and the long period will make it break too straight, but it’s the size that’s the real issue.

Tuesday, 8 September, is the last day of the forecast. The swell drops to 8.2 ft from the west, with a 10-second period and a strong 1277 energy. The wind is a cross-on 16 mph from the NW, so it’s going to be choppy and lumpy. Still too big for beginners, and only really for experts willing to battle the wind.

So, to sum it up: in
