The Lowdown
Alright folks, Rusty here. Let’s be straight with you – looking at this 16-day window for Mawgan Porth, it’s a tough watch. I’m not going to sugarcoat it; the surf forecast is pretty grim, and there are no good recommendations on the cards. The whole run is basically a write-off for a decent paddle.
The water’s sitting at 65°, which is a touch warmer than normal for this time of year, so at least it’ll be comfortable sitting out there waiting for a wave that never really comes.
We’ve got a blank run stretching from now, right through the whole 16 days. Every session is tagged with "poor surf conditions." The issue is the wind. It’s almost always howling onshore, cross-on, or straight on from the west to northwest – just killing any chance of clean faces. Even when there is some size, like on the morning of Monday, September 7th when a 7ft WNW swell rolls in with a long 13-second period and very strong energy (1632), it’s blowing straight onshore at 16 mph. That’s just ugly, blown-out junk.
That same week sees some pulse of energy – Tuesday morning the 8th has 7ft at 9 seconds with 670 energy, but that WNW wind is howling at 19 mph, cross-on. It’s lumpy, messy, and honestly, looks more interesting for the kite surfers than anyone on a paddle board.
By the time we get to the end of the run, like Monday, September 21st, we see a bit of a spike – 6ft early and then a solid 12ft later in the day with 2205 energy. But again, the wind is on it, and the period has dropped right off to 7-9 seconds. That 12ft is going to be a washing machine under those conditions – strictly for experts only, and even then, it won’t be pretty.
So here’s the hard truth: there isn’t a single standout session in this entire 16-day run. It’s a blank stretch. The combination of persistent onshore winds and poor conditions means you’re better off doing something else. Forecasts change, but right now, this is a solid skip.
