The Lowdown

Alright folks, Rusty here. Let's have a look at what Mawgan Porth has got cooking for us over the next couple of weeks. I'll be straight with you, it’s a bit of a grim stretch, so don't get your hopes up too high.

Right off the bat, we’ve got a bit of swell rolling in this Sunday afternoon, the 13th of September. We’re looking at a 5ft swell from the west with a 10-second period. But here’s the kicker – the wind is howling from the WSW at 15 mph, putting a nasty cross-on chop all over it. The combined energy is moderate at 439, but honestly, the conditions are just poor. It’s not going to be any fun out there.

Things don’t really improve for the rest of the week. Monday and Tuesday keep that cross-on wind going, with the swell bouncing between 4ft and 6ft. The period drops to a short 8 seconds on Tuesday, so the waves will be weak and crumbly. The energy jumps up, hitting 877 on Wednesday morning with a 6ft swell from the W and an 11-second period, but the wind is still cross-on from the NNW at 19 mph, just ruining it. It’s a classic case of "looks good on paper, rubbish in the water." The water temperature is sitting at 64°, which is a touch warmer than usual for this time of year.

The whole first week is pretty much a write-off. We see some offshore wind trying to clean things up on Friday the 18th, but the swell is still moderate, and the wind swings back around to cross-on in the afternoon. By the weekend, we’re still dealing with onshore winds and short-period, choppy surf. This is a river break, so the lack of any decent shape with these winds makes it pretty unattractive for a paddle session. Honestly, with these winds and the open exposure, the setup looks more interesting for kite surfing than paddle surfing.

We do get a little glimmer of hope heading into the third week. On Monday the 21st, the swell drops right off to 3ft, but the period stretches out to a very long 13 seconds. The wind goes light and cross-shore from the south at 6 mph. It's only a 1 out of 10 on the score, described as "marginal," but it’s the best we’ve seen in a week. Tuesday the 22nd sees a bit more size at 5ft, but it’s short-period windswell with a cross-shore wind, so still no good.

The cleanest conditions of the whole forecast come on Wednesday the 23rd and Thursday the 24th. The wind goes cross-off from the NNE, creating clean surf. On Wednesday the 23rd, there’s a 7ft swell from the WNW, which is a bit on the bigger side for beginners, and the 7-second period means it will be weak and sectiony. On Thursday the 24th afternoon, we get a tiny, clean 2ft wave from the west with a 9-second period. It’s described as "surfable waves but very ordinary conditions." That’s about as good as it gets.

After that, we’re into a real dry spell. From Friday the 25th right through to the end of the forecast on the 28th of September, the swell is tiny – under 2ft. The wind is offshore and clean, which is nice, but there’s just no energy to work with. The combined energy drops to just 39. It’s a flat spell. So, to sum it up, there’s no standout period. The best you’ll get is a few small, clean waves on the 24th if you’re desperate. Otherwise, keep the board in the car and wait for a better forecast.

Rusty.
