The Lowdown
Alright folks, Rusty here. Let's have a look at what Mawgan Porth has in store for us for the next couple of weeks.
Honestly, it's a tough spell ahead. The whole 16-day window is pretty much a write-off for decent surf. There are no good options on the table. Every single session flagged shows "poor surf conditions," and it’s not just a day or two—this looks like a prolonged blank run that's more normal for the area when the weather patterns lock in. We're looking at a solid two weeks of onshore winds, lumpy chop, and blown-out waves.
Right off the bat, Tuesday the 25th sees a small 2ft west swell with a 10-second period, but a moderate SE breeze makes it a messy cross-off. The combined swell energy is a weak 92, and this pattern just repeats day after day. The water is sitting at 65°, which is a touch warmer than normal for this time of year. Wednesday the 26th and Thursday the 27th are much the same—tiny, weak, and messy.
Things get a bit more energetic starting Friday the 28th, with the combined energy hitting a moderate 139 by morning, but that 3ft southwest swell is under a cross-onshore wind, making it choppy. By Saturday the 29th, the swell jumps to 6ft with 325 energy, but it's under a fresh 18 mph cross-onshore and a risk of thunderstorms, so the quality is shot.
Sunday the 30th offers the biggest energy of this early period at 476, with a 5ft west-northwest swell and a 10-second period. But again, the wind is all wrong. It's a messy, poor setup. The second week of September sees a real wall of energy on the 7th and 8th, with combined readings over 2000 and swells hitting 12ft. That's expert-only territory if the wind was right, but with onshore and cross-onshore winds in the 28 mph range, it's just a washing machine. With that much wind and size, the setup looks more interesting for kite surfing than paddle surfing.
Don't hold your breath on this one. It's a flat, blown-out run with no standouts at all.
