The Lowdown
Right then, let's have a look at what Mawgan Porth has in store for us over the next couple of weeks. I won't lie, it's a quiet stretch. For a few days here, there's just not much to get excited about. The biggest problem is that while we get some pulses of swell, the wind is often in the wrong place, chewing up the waves before they have a chance to look good.
We kick off on Monday the 10th with a weak 2.6ft swell from the WNW, but a cross-shore wind is making a mess of it. The water temp is 66°, a touch warmer than normal for the time of year. It's a write-off. Tuesday looks identical in size but with a cleaner wind, though the waves are too small at 1.3ft. Wednesday the 12th is where we see a flicker of life. The swell from the West bumps up to 2.6ft and the energy is moderate (124). The real treat is Wednesday afternoon: glassy conditions with the wind dropping to zero. That will be clean, but with only 2.6ft of swell, it's just a fun little mellow session, not a standout.
A bigger pulse arrives on Thursday the 13th with a 3.6ft West swell and solid energy (267), but the wind has swung cross-on, ruining any hope of quality. That pattern of a bit of size but blown-out choppy conditions persists right through the weekend. Saturday the 15th sees a 3.3ft swell, but it's also cross-shore and messy.
There's a glimmer on Monday the 17th: an offshore wind from the ENE at 19 mph will create the cleanest conditions of the whole period, but there's only 1.3ft of swell to work with. It'll be tiny and perfect for a longboard or a beginner's first pop-up. That clean offshore wind and light conditions hold for the 18th too, with the swell bumping to 3.3ft and clean waves, but the period is a short 7 seconds. The energy is moderate (130), but it'll be a bit weak and lumpy.
The best wave energy of the entire forecast hits on Tuesday the 25th of August: a 4.9ft west swell packing strong energy at 332. But here's the heartbreaker: the wind is cross-on and choppy. For a true stand-out session at Mawgan Porth, you need that west swell with a clean offshore or glassy wind, and we just don't get that combination in this 16-day window. The best on offer, really, is that Wednesday the 12th afternoon in the glass, or the clean but tiny Monday the 17th. For the rest of it, if you've got a kite, you might be better off than the rest of us on a surfboard.
