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.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
