The Lowdown
G'day, Rusty here. Look, I've had a good look at what's on offer for Mawgan Porth over the next couple of weeks, and I'll be straight with you – it's a tough stretch. We're looking at a long, flat spell with barely a ripple worth paddling for, so don't be holding your breath for any hero sessions.
The water's sitting at about 65°, which is a touch warmer than normal for this time of year, so at least it won't be a cold wait. The wait itself is the main story here. From now through the end of July and into the first week of August, it's nearly all "poor surf conditions" with combined energies barely cracking 60 (like 53). We're talking tiny waves, barely 1.0 ft to 2 ft, with short, weak periods of 6-9 seconds and onshore or cross-off winds messing things up. There's a brief moment on the morning of Sunday, August 2nd, where it goes glassy, but it's still only 2 ft – barely a bump. The morning of Monday, August 3rd, is the first time we get a "surfable" mention, with 2 ft swell from the WSW, but it's only a 1 out of 10 on the quality scale, so don't expect much.
The good news is that things start to look up on Saturday, August 8th. From the morning of the 8th through the 9th, we get a proper pulse of energy. The Saturday morning brings 3 ft from the WSW with a 10-second period, and the combined energy jumps right up to 161 – that's moderate energy. The wind is blowing fresh offshore from the ESE at 22 mph, which is clean, clean, clean. This would be the standout window. The afternoon keeps 3 ft from the WSW, energy at 190, and a cross-offshore breeze, so still good. The same setup continues into Sunday, August 9th, with 2 ft from the SW and clean cross-off winds, though the energy drops back to 82.
Forget about the beach setup here with 3 ft swell – it's not too big for anyone, and that long period (10 seconds) will help shape things up nicely. Because the wind is so clean and the swell direction (WSW) is a solid match for the optimum WNW, this is the one to aim for. Those few days around the 8th and 9th are the best on offer. After that, it drops right off again into tiny, weak junk through to the 13th.
So, if you're flexible, keep your eyes on Saturday, August 8th, for the best chance of a few clean ones. It's a long-range call, so don't book time off work just yet, but it's the only real light in this tunnel.
Rusty.
