The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Mawgan Porth.
Right off the bat, I gotta be straight with you – this is a tough one. We’re looking at a long, dry spell with hardly any surf to get excited about. The whole 16-day window is basically a write-off for any decent waves. There’s a big gap from now until Tuesday the 21st of July where the surf is just poor, with tiny heights and messy wind. You’d be better off checking the forecast again in a few days.
Now, Tuesday the 21st of July morning is the only time that even flickers to life. It’s not a stand-out, but it’s the best we’ve got. The swell is a tiny 3ft from the NNW with a short period of 6 seconds, so it’s not going to have much punch. The combined energy is a weak 76. But here’s the thing – the wind is glassy, dead calm. That’s a big positive. For a beginner-friendly spot like Mawgan Porth, those super clean, glassy conditions will make the small, weak waves feel a lot more fun. There will be no crowds to worry about either, so you can have the place to yourself.
The rest of the period is a total bust. Wednesday the 22nd and Thursday the 23rd see a bit more size, up to 4ft, but it’s all from the north with strong, lumpy cross-shore winds. That’s just a choppy mess. After that, we’re back to tiny, almost flat waves with onshore winds and rain by the end of the month. The 28th of July afternoon and 29th of July morning do show a jump in combined energy to 132 and 127, but that’s coming with strong onshore winds from the west-northwest. It’s raw, blown-out, and not for paddling. Honestly, that setup looks more interesting for the kite surfers than anyone on a longboard.
So, bottom line: mark your calendar for Tuesday morning the 21st of July for a glassy, tiny session, but don’t expect much else. The water is a touch warmer than normal for the time of year, sitting at 64°.
Rusty.
