The Lowdown
Right then, let’s have a look at what’s cooking for Mawgan Porth over the next couple of weeks. I’ll be straight with you – it’s a pretty bleak run for the most part. We’ve got a real gap of surfable waves for the first week, and then only a couple of fleeting moments that might get your heart rate up.
The pattern is mostly small, weak, and choppy. The combined swell energy is rarely above 100 (it’s mostly in the low double digits, like 31 or 60), which tells you there’s hardly any push. The wind is a constant problem, too – a lot of cross-onshore and onshore slop from the NW and WNW, making everything messy.
Saturday the 25th and Sunday the 26th are a write-off. Tiny waves, 2 ft to 7 ft, but with a nasty cross-onshore wind, it’s just a washing machine. That 7 ft on Sunday morning is actually the biggest of the whole period, but with a 7-second period and fresh cross-onshore wind, it’s a lumpy, closed-out mess – only for the keenest, and even then, it’s not fun.
Monday the 27th is a little better with a cleanish morning, but the swell is dropping quick to 3 ft. Still, the wind is a light cross-onshore, so you might find a crumbly little wave if you’re desperate. The energy is still weak (168).
Then we hit a proper flat spell. From Tuesday the 28th right through to Sunday the 3rd of August, the swell is tiny, mostly under 3 ft, with energy values below 100. The wind is a mix of cross and cross-off, but the waves just aren’t there. It’s a long, boring gap.
The first real standout doesn’t arrive until Wednesday the 5th of August. The morning is showing a 8 ft swell from the W with a 9-second period, and the combined energy is a massive 1064 – that’s strong, proper groundswell energy. The wind is a clean cross-off from the NE. This is the best on offer by a long shot. The size is right on the edge for beginners (over 5 ft), but for any intermediate or above surfer, this is a genuine window. The water temperature is about average for the time of year, so no surprises there. The caveat is the swell period is 9 seconds, so it’s a bit of a mix of ground and wind swell, but with that energy and clean wind, it’ll be a fun, punchy morning. The afternoon gets a bit wonky with a 10 ft swell and a cross-shore wind, so get out early.
Thursday the 6th of August has some leftover 6 ft swell, but the wind turns cross-onshore again, ruining it. The energy is still decent (373), but it’ll be lumpy.
After that, it’s back to the small stuff. The second week really fades out. Saturday the 9th of August has a clean, cross-off wind and a tiny 1 ft swell, but it’s just a dribble. The energy is 62, so nothing to get excited about.
So, the one and only true standout is Wednesday morning, the 5th of August. If you can get on it, do it. Otherwise, it’s a long wait for not much.
