The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for Mawgan Porth is a long, frustrating stretch of flat or poor-quality surf. The first proper surf that’s worth paddling out for doesn’t show up until Friday the 31st of July, and even then, it’s not a gift for everyone. Before that, we’re looking at over a week of tiny, weak, and messy waves. The water’s a touch warmer than normal for this time of year, about 65°, but that’s small comfort when you’re scratching for a ride.
The first real window of opportunity is on Friday the 31st of July. The morning brings a solid 8 ft swell from the west, with a period of 8 seconds. That’s a big, powerful lump of water – the combined energy is a strong 1038, so it’ll have plenty of punch. This is strictly for experienced surfers; it’s too big for beginners. The wind is offshore from the east at 12 mph, which will keep the faces clean, and the break is a river mouth, so the long period isn’t as much of a worry. That morning is the standout, no doubt. The afternoon drops a bit to 6 ft, but still clean with offshore wind, so it’s a decent session, though the crowd factor at Mawgan Porth can be an issue, so be prepared for company.
After that, the swell fades quickly. The next couple of days are a letdown – Saturday the 1st of August has a 3 ft swell but the wind swings onshore in the afternoon, and Sunday the 2nd is just choppy cross-on slop. The last glimmer of hope is on Tuesday the 4th of August, where we’ve got a 6 ft swell from the WNW with a 9-second period (energy around 572), but the wind is straight onshore at 16 mph. That’s a choppy, blown-out mess. It’s big, but the quality just isn’t there for a paddle. The setup looks more interesting for kite surfing than paddle surfing.
So, to sum it up: the whole 16-day run is a barren stretch until the 31st of July. That Friday morning is the one true standout, and after that, it’s a slow fade into poor conditions. If you’re patient, that Friday could be a ripper for the experts, but don’t hold your breath for the rest.
Rusty.
