The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's on the cards for Mawgan Porth.
Right off the bat, I gotta be straight with you – this 16-day outlook is a tough one. The first bit of surf we see is on Monday the 3rd of August, with a tiny 2ft swell from the WSW, but the real kicker is the energy is weak – only a rating of 65. The water’s sitting at 65°, which is a touch warmer than normal for this time of year. It’s glassy, which is a beautiful thing, but the waves themselves are just so-so. Nothing to get excited about.
Tuesday morning the 4th, the wind swings SW and pumps up to 16 mph, turning it into a choppy, cross-onshore mess. The swell bumps up a bit, but it’s short-period slop. That theme pretty much holds through the rest of the week. Wednesday the 5th sees a bigger pulse of swell – 6ft from the WNW – but the wind is howling onshore at 16-19 mph, so it’s just a blown-out wall of whitewater. The energy is moderate (383), but the conditions are poor. By Thursday the 6th, we’re back to smaller, choppy stuff.
We hit a real flat spell from Friday the 7th through Sunday the 9th, with waves barely breaking 2ft. The wind is light and clean at times, but there’s just no swell to work with. Monday the 10th and Tuesday the 11th offer a bit of hope with some clean, offshore winds, but the swell is laughable – 1ft and 0.7ft. You’d be bobbing around more than surfing.
The second week doesn’t offer much redemption. The swell tries to pick up a bit around the 14th and 15th of August, with the 15th seeing a 6ft groundswell from the W and moderate energy (359). But once again, the onshore wind ruins it.
Honestly, looking at this whole window, there isn’t a single standout session. The setup is more interesting for the kite surfers than for us paddle boarders, with consistent onshore winds and chunky, messy waves. It’s a rare blank run for this area, but it happens. The swell direction is all over the place, and the wind never really plays ball. Stay home, wax up the board for the next one, and hope the forecasts change.
Rusty.
