The Lowdown
Alright, Rusty here, let's have a look at what's cookin' for Mawgan Porth over the next couple of weeks. Honestly, it's a bit of a tough read for us paddle surfers.
Right off the bat, we've got a long stretch of pretty disappointing conditions. There's tiny, weak swell, with energy barely registering (42 to 96), and when the wind is favourable, the waves are just too small to get excited about. You'll see a bit of life on Saturday the 22nd, with a 2ft swell from the W, period around 10 seconds. The morning is your best shot with a light offshore ENE breeze making things clean, but it's weak energy (96). Not a standout, just the best of a bad bunch early on.
Then things go flat or messy for days. From Sunday the 23rd right through to Wednesday the 27th, it's all tiny surf or blown out with onshore winds. There's a real low point in the middle of that week.
Now, Thursday the 27th morning kicks up some serious size – a 10ft swell from the W, but with a short period of 8 seconds and a cross-onshore wind. The energy is massive (1331), but the wind is going to make it a washing machine. That's honestly more of a kite-surfing kind of day. Not recommended for a clean surf.
The pattern stays poor through the rest of August and into early September. There's a lot of onshore wind, strong sideshore breezes, and lumpy conditions. A few days (like Sunday the 1st) drop back to tiny 3ft waves, but the onshore wind kills it.
The only real flicker of hope comes on Wednesday the 2nd of September. The afternoon shows an 8ft swell from the W, period of 10 seconds, with a cross-shore wind. The combined energy is strong at 1630, and the wind is moderate cross-shore, which could set up some decent, grunty waves if it cleans up. It's marked as marginal, but it's the best size and energy we see in the whole run. It's still a bit big for beginners over 5ft, but for anyone comfortable in that range, it's the one to watch. Thursday the 3rd gets even bigger (10ft, 11-second period, energy 2423) but the cross-onshore wind makes it a messy, expert-only affair.
So, if you're desperate for a session, that Saturday morning (22nd) for a tiny, clean wave is your only real option for a long while. Otherwise, keep an eye on that Wednesday the 2nd of September for a possible window of proper surf.
Rusty.
