The Lowdown
Alright folks, Rusty here. Let's have a look at what Mawgan Porth has in store for us over the next couple of weeks.
Well, I gotta be straight with you – it’s a tough stretch ahead. For the first week or so, we’re looking at a whole lot of nothing. The swell is tiny, the winds are messy, and the energy is weak. You’re not missing a thing. The water is sitting at 64°, which is a touch warmer than normal for this time of year, but that's about the only positive.
We’re looking at a gap of several days with pretty much no surf worth paddling out for. It’s not until the morning of Monday, the 29th of July that things finally start to look a bit more interesting. That morning, we’ve got a 7ft swell rolling in from the west with a 9-second period. The energy jumps right up to a strong 613, and the wind is light and cross-shore, leaving the surface clean. That’s a proper wall of water, but at over 5ft, it’s getting a bit meaty for the beginners. The afternoon gets a bit choppier with a stronger cross-onshore breeze.
Then into the morning of Tuesday, the 30th of July, we’ve still got a solid 5ft west swell, energy in the moderate-to-strong range at 363, and again a light cross-shore wind making for glassy conditions. It’s another clean window, but the swell direction is more west than optimum, so it’s not a perfect match for the river mouth.
Honestly, the standout here is Mawgan Porth on the morning of the 29th. That's the biggest, cleanest, most powerful surf we’ll see in this whole forecast, but it’s also the only real highlight in a very average outlook. The wait is long, but that one session has some proper grunt.
Rusty.
