Mawgan Porth Surf Forecast and Surf Report

G'day, I'm Rusty. Look, I've got to be straight with you – the next 16 days at Mawgan Porth are shaping up as a real tough stretch of very ordinary conditions. The good news is that there is a window of surfable waves, but you've got to pick your moments carefully. The water temp is sitting at 66°, which is a touch warmer than normal for this time of year.

Starting things off on Tuesday the 11th, we're looking at small, weak, uninviting surf. Combined energy is only 29 and 31, with a tiny 1ft to 0.7ft swell. The wind is a cross-off but it's a moderate 12 mph breeze, so it's not all bad, but there’s hardly any wave to ride.

Wednesday the 12th is where it gets slightly interesting. The morning sees a small 3ft swell out of the west, with a combined energy of 126 – that's moderate wave energy – and the cross-off wind is a light 6 mph. It’s rideable. But Wednesday afternoon is your real standout for the whole outlook: a glassy 3ft westerly swell with a combined energy of 139, and the wind dropping to a 3 mph, glassy state. For a river break that's fairly exposed and consistent, this is the cleanest you'll see. Crowds can be likely here sometimes, so get in the water then. This is the one to aim for.

From Thursday the 13th onwards, things fall apart. Moderate to fresh cross-onshore winds kick in, and the swell bumps up to 4ft but gets chopped to bits. Scores are zero across the board. There’s a gap of several days with no real recommendations. Saturday the 15th and Sunday the 16th see tiny 2ft swell with weak combined energy.

Monday the 17th brings a cleaner cross-off wind with a 4ft west swell and moderate combined energy of 231, but the wind is a brisk 12 mph, so it's not perfect. Tuesday the 18th morning again offers a brief clean chance with a 3ft swell, but the energy drops right off.

The stretch from late in the second week, specifically from the 23rd of August, gets punchy but messy. Sunday the 23rd has a 6ft southwest swell and strong combined energy of 458, but with onshore and cross-onshore winds over 25 mph, it'll be a washing machine. Monday the 24th sees a solid 12ft westerly swell with a very strong combined energy of 1970 – that's proper power – but it's absolutely howling onshore at 28 mph. That's pure chaos, only for absolute experts, and the setup would be more interesting for kite surfing than paddle surfing. That swell cleans up through Tuesday the 25th with a 8ft west swell and still strong onshore winds.

In short, you've got a tiny glassy window on Wednesday afternoon the 12th. That's your best shot at something clean. After that, it’s a long, frustrating wait with mostly poor conditions until the second week's bigger but wind-affected swell arrives.

Rusty.
