Alright surfers, Rusty here. Let’s have a look at what’s coming up for Mawgan Porth.
Right off the bat, we’ve got a pretty flat start. The first few days are all about tiny, weak swell and that’s just not worth paddling out for. The water is sitting at 64°, which is a touch warmer than usual for this time of year, so at least it’s comfortable if you’re just going for a swim.
The real action doesn’t show up until Tuesday 21st July. That’s the standout in this whole 16-day window. We’ve got a solid 5ft swell rolling in from the WNW, with a 9-second period. The energy is pumping into the bay at a strong 487 (combined energy), and the wind is light and cross-offshore from the ENE. That’s clean, lined-up surf. The river mouth should be handling it well, with some nice little peaks breaking top to bottom. It’s not huge, but it’s the best we’re going to see by a long shot. Expect a few others out there, but nothing too hectic.
The next morning, Wednesday 22nd July, is still worth a look. The swell drops a touch to 3ft from the WNW, but with the same light cross-off breeze, it’ll stay clean and fun. The energy is still moderate (203), so there’s enough push for a decent session.
After that, it tails off quickly. The rest of the week is small, messy, or onshore. There’s a pulse right at the end of the period on Sunday 26th July – a 6ft swell from the WNW, but the wind swings onshore from the west in the afternoon, which will chop it up. The morning could be a wildcard if the wind plays ball, but it’s a long way out and pretty uncertain.
So, to sum it up: the next week and a half is mostly a write-off. Your only real window is Tuesday 21st and Wednesday 22nd July. Don’t sleep on it.
Rusty.
