The Lowdown
Alright folks, Rusty here. It’s been a tough stretch to be a surfer in this neck of the woods. We’ve got a 16-day window ahead, but to be honest, the surf is almost non-existent for the first ten days, and what does show up is messy.
We’re looking at Mawgan Porth, a river mouth setup that’s fairly exposed to the swell. The water is sitting at 65°F, which is a touch warmer than normal for this time of year, so you won’t need the thickest rubber.
The first real chance of anything rideable doesn’t arrive until Thursday morning, July 23rd. We’ll see a tiny 3ft swell from the NNW with a period of 6 seconds, which is weak and short-period. The wind will be glassy, though, which is a rare treat. The combined swell energy is a paltry 78 – hardly any grunt. It’s surfable but very ordinary, and honestly, it’s about the only window that’s even worth a look.
After that, we hit a long, dead stretch. From Thursday afternoon, July 23rd all the way through to Friday, August 1st, the forecast is a continuous run of poor surf conditions. The wind is mostly onshore or cross-onshore, and the swell is either too small or too weak. The periods are short, and the energy readings are mostly in the double digits, which is about as weak as it gets.
The next time we see any significant size is around Sunday, August 2nd. We’ve got a 5ft swell from the west with a 9-second period, which is more powerful with a combined energy of 356. But the wind is a fresh cross-onshore from the WNW, making it lumpy and ugly. The swell is over 5ft, so it’s getting too big for beginners, and with the choppy conditions, it’s not a great bet for anyone.
The standout, if you can call it that, is that brief Thursday morning, July 23rd session. The 3ft swell from the NNW is tiny, but the glassy wind will make it look better than it is. It’s the only clean window in the whole outlook. For the rest of it, the conditions are just too rough, and the swell is too weak or poorly aligned. Honestly, this stretch looks more like a kite-surfing setup than a paddler’s paradise.
This is a tough run. The lack of consistency and the onshore winds mean you’ll be waiting a long time for a decent wave. Forecasts can change, but right now, it’s a waiting game.
