The Lowdown
Alright folks, it’s your mate Rusty here. Let’s have a look at what’s on offer for Mawgan Porth over the next couple of weeks.
To be honest, the outlook is a pretty tough one for the next week and a half. The surf is mostly on the small side, and the wind is going to be a real pain. We’ve got a lot of cross-onshore and onshore winds messing up what little swell we get. There’s a bit of a tease with a 5ft swell on Friday morning the 11th, but it’s coming with a cross-on breeze and only a 1 out of 10 quality call, so it’s hardly worth getting excited over.
The real standout is looking like Saturday the 19th of September, but it’s not for the faint-hearted. We’ve got a solid 8ft to 10ft swell arriving from the WNW, with a massive combined energy of 881 to 1106. That’s serious power. The period is only 8 seconds though, so it’s a short-period wind swell, not a clean groundswell. At that size, it’s expert territory only. The wind is light and onshore for most of it, so conditions will be rough and lumpy. It’s a big, messy wall of water for the pros.
The only other glimmer of hope is a couple of mornings with clean conditions and cross-offshore winds. Tuesday the 22nd of September will see a small 4ft swell from the west with a short 7-second period, and a decent 3ft swell on Thursday the 24th with a longer 11-second period and an offshore wind. The 24th looks the pick of the bunch for a clean, surfable wave, even if it’s only average. For a beginner, this is the best window.
The water temperature is sitting at a very unusual 65°F for this time of year, which is much warmer than normal for the first break.
Overall, it’s a grim run for paddle surfing. The consistent wind and chop would make Mawgan Porth a better playground for the kite surfers through the middle of the period.
Rusty.
