The Lowdown

Alright, grab a coffee, it's Rusty here, and we've got a proper look at what's cookin' for the next couple of weeks. I'll level with you, straight off the bat – it's not a classic period for Mawgan Porth. We're staring down the barrel of a long, drawn-out run of poor conditions. The first surfable recommendation doesn't pop up for a while, a real gap of quiet, and even then, it's nothing to write home about. Let's walk through it.

As we go into late August and the start of September, the story is a persistent onshore and cross-onshore wind, mostly from the west or southwest. The combined swell energy is all over the shop, from a weak 70 all the way up to a very strong 1085 on the 31st of August morning, but with howling cross-onshore winds, those 8ft waves are just a mess. It's all lumpy, choppy, and blown-out. Not worth getting the wetsuit wet for a paddle. Honestly, a couple of those afternoons with the strong breeze and 7ft+ swell – that's more of a kite surfer's playground than a surfer's dream.

We get a tease of a proper looking swell around the 1st of September. Morning and afternoon, the wind goes clean offshore from the west. The swell is a modest 4ft and 3ft respectively, with a solid 9-second period from the west. The combined energy is moderate (231 and 158). It's a clean wave, no doubt, but the guidance still calls the surf quality poor, and the size is small. It's a glimmer of hope, but not the standout.

The wind stays onshore for the first week of September, bouncing between cross-on and cross-off. The swell sticks around, but it's messy. There are periods of moderate wave energy (between 268 and 496 on the 2nd, 3rd, and 4th of September) but again, the quality just isn't there. It's fresh onshore breeze after fresh onshore breeze.

Now, here's the one that perks my ears up. On the morning of Sunday the 6th of September, we finally get a clean window. The wind swings around to a moderate offshore from the east at 12 mph. It's a small wave, only 2ft from the west, but with a decent 9-second period. The combined swell energy is weak (83), and the guidance calls it "surfable waves but very ordinary conditions," scoring it a 1. The inconsistent and weak nature of the energy means the sets will be small and far between. It's hardly a standout, but in this 16-day window, it's the only clean look we have.

Everything after that flaps around again. The 7th of September shows some moderate swell energy (402) but the wind is onshore, and the period is short (7-8 seconds). The 8th through the 12th of September is a real mixed bag of weak energy (28 to 91), short periods (5-6 seconds), and cross-onshore winds. The water temperature is about 2°F warmer than normal for the time of year, currently sitting around 65°, but that's small comfort when the waves are so ordinary.

Honestly, for this stretch, your best bet is to keep an eye on the morning of the 6th of September. It's an early start for a small, clean wave. If you're desperate for a paddle, that's your window. Otherwise, it's a waiting game.
