Alright, let’s break down what’s happening at Mawgan Porth.
Honestly, the first ten days are a tough watch. We’ve got a lot of onshore and cross-onshore wind, and the swell is tiny and weak. The combined wave energy is barely a whisper for most of that time – numbers like 335, then dropping to 198, 166, and eventually down into the double digits like 99 and 77 (energy readings). The swell is hanging around 2ft to 4ft, mostly from the west with a 9 to 10-second period, but the wind just won’t cooperate.
Friday morning, July 3rd, is the only half-decent window early on. You’ve got a 4ft west swell at 10 seconds, but with a light cross-on from the WSW it’s only marginal. The water temp is about average for the time of year. After that, it’s a solid run of poor surf right through until the end of the first week and into the second. There’s a glimmer on the morning of Wednesday, July 8th, with a clean cross-off breeze and a tiny 2ft west swell, but it’s very ordinary. Then on Friday, July 10th, the morning brings a clean offshore wind from the east with a 2ft west swell that’s starting to show a little more energy (123), and the afternoon even goes glassy for a 2ft west swell (109). It’s surfable, but small.
Now, the real highlight – and I mean the only standout – comes Monday, July 13th. The swell jumps to 5ft to 6ft from the west, with a long 12-second period. That’s a proper groundswell. The combined energy spikes to 815 and 862, which is strong. But here’s the catch: the wind is cross-onshore both morning and afternoon, so the conditions are poor. Still, for an open beach like Mawgan Porth (this is in Cornwall, United Kingdom), that much energy with that long a period could produce some fun, lumpy waves for those who don’t mind a bit of chop. The water temp is about average. If you’re a beginner, that 5ft+ is getting punchy, and the long period might make it break a bit too straight for a beach break. It’s more of a challenge for the experienced crew.
After that, the swell drops back again through the rest of the week, with winds staying messy and onshore. There’s a pulse from the north on Friday, July 17th, with 7ft to 7ft of swell, but it’s a short-period 7-second windswell and the wind is onshore and strong. That one’s a mess, and at that size, it’s only for experts or foilers.
So, truth be told, the best on offer is that Monday the 13th. It’s not clean, but the size and energy are there. For the rest of the run, you’re better off waiting for a better wind day. This isn’t a great stretch for paddle surfing – if the wind keeps up, the kites will be having more fun.
Stay patient,
