The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s cookin’ for Mawgan Porth over the next couple of weeks.
Right off the bat, I gotta be straight with ya – it’s a rough stretch. There’s barely a heartbeat in the surf for days on end, and a whole lot of windy, messy junk. The first few days are basically a write-off. Tuesday the 4th through to Saturday the 8th? Forget it. We’re talkin’ weak, short-period windswell, mostly cross-onshore, with energy barely ticklin’ 100 (between 22 and 394). The water’s about average for this time of year, nothin’ weird goin’ on.
Now, there is one tiny glimmer. On Sunday morning the 9th, things clean up a bit. A light cross-offshore breeze from the NNE, and the waves clean up. But it’s tiny – only 3ft out of the west, with a short 7-second period. The combined energy’s a weak 69. It’s surfable if you’re desperate, but it’s ordinary.
The rest of the week into the second week is just more of the same – poor, choppy, onshore crud. You get a bit of glass on Saturday the 8th morning, but with 1ft, it’s barely a ripple. By the time we hit the 18th and 19th, the swell tries to pick up – Tuesday the 18th afternoon sees 6ft west swell, and Wednesday the 19th morning pushes 7ft from the WNW with a 9-second period and a combined energy of 603 (moderate). But the wind is onshore and cross-onshore, so it’s gonna be messy. That’s expert-only territory, and honestly, the setup’s lookin’ more interesting for kite surfing than paddle surf.
There are no standouts here, mate. It’s a tough 16-day window for Mawgan Porth. But it’s a fairly consistent spot, so don’t lose hope – forecasts can change.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Mawgan Porth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
