The Lowdown
Alright, folks. Rusty here. Let's break down the next couple of weeks for the surf.
Honestly, it's a grim outlook for Mawgan Porth. The entire 16-day window is a total write-off. There’s not a single session that gets the thumbs up. The forecast is just a constant stream of poor conditions, with wind and swell completely out of sync.
We're looking at a big gap of flat, messy, or blown-out days. The first week is especially rough. Right from the start, we've got a fresh cross-onshore wind with a short-period, weak 1.7m swell from the WSW that's just lumpy and ugly. That sets the tone. The water temperature is sitting at 18°, which is a touch warmer than normal for this time of year, but that's little comfort when the waves are junk.
There's a brief moment on the 4th of September with a bit more size – 2.1m from the west – but the wind is onshore and it's still a short-period 8 seconds, so it's just a big, blown-out mess with moderate wave energy (617). Not worth it.
The 5th of September sees a drop in size to 1.3m, but the period stretches to 11 seconds, giving a bit more shape. The combined energy is moderate (403), and the wind is light, but it's still a cross-on breeze. The report calls it marginal, and I'd agree – it's the closest thing to a maybe, but still not a recommendation.
After that, the swell drops right off. By the 6th, we're down to 0.6m with clean winds, but it's just too small. Then a bigger pulse hits on the 7th and 8th – 2.0m to 2.4m from the west-northwest – but the wind is onshore or strong cross-onshore, creating a lumpy, choppy mess. The combined energy spikes into the strong range (881 to 1079), but with that wind, it's a battle, not a pleasure.
The second week doesn't offer any salvation. The swell keeps coming in pulses, but the wind is always wrong. We've got a strong breeze on the 14th with 1.2m swell and a 12-second period, but it's a strong cross-onshore that'll have you fighting for your life. The last few days of the window drop to barely 0.6m, with gale-force winds on the 16th making it a complete no-go.
So, to sum it up: there's nothing to recommend here. The surf just isn't on. It's a blank run, and for this area, that's not unusual when the wind and swell don't play ball. Keep an eye on the charts, but for now, save your energy.
Rusty.
