Mawgan Porth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get real about what’s on the table for Mawgan Porth over the next couple of weeks. I’ll be straight with you – it’s a bit of a flat and messy run for the most part, so patience is the name of the game.

We kick off on Friday, the 10th of July. The morning is about as clean as it gets – glassy offshores from the east at only 3 mph, and a little 3ft swell rolling in from the west with a 9-second period. The water is sitting at 63°, which is a touch warmer than normal for this time of year – you’ll feel that difference. The combined energy is moderate, sitting at 134, but honestly, these are surfable waves in very ordinary conditions. Nothing to write home about, just a little ankle-to-knee-high dribble to get the wetsuit wet. The afternoon stays clean with a light breeze but the swell drops a notch to 3ft.

Saturday the 11th is a step down – the swell shrinks to 2ft in the morning and 2ft in the afternoon. Winds are cross-offshore but picking up, and the energy drops to 108 and 91 respectively. Poor surf conditions.

From Sunday the 12th all the way through to Sunday the 19th of July, there’s a long stretch of poor conditions. That’s a full week of flat, weak, or messy surf. Swell heights mostly below 2ft, short periods, and combined energy values consistently below 100 – weak stuff. Winds are often offshore or cross-offshore, which keeps the surface clean, but there’s just no size or push to work with. The exception is Saturday the 18th, when we see a jump in swell to 6ft from the north with a period of 7 seconds. Energy jumps into the moderate range at 351, but the wind is a fresh cross-shore at 19 to 25 mph, making it lumpy and choppy. That’s more of a kite-surfing wind than a paddle-surfing wave.

Then on Monday the 21st of July, there’s a flicker of hope. Morning has 5ft from the west-northwest and moderate energy at 173, but the wind is cross-onshore and choppy. By the afternoon, the swell settles at 4ft from the west with a 7-second period, and energy rises to 279. Winds ease right back to a light breeze, but it’s still cross-onshore with small wind ripples. Marginal.

The standout in the entire 16-day window – if you can call it that – is Wednesday the 22nd of July morning. That’s the one to circle. You’ve got 4ft from the west-northwest at a 9-second period, combined energy of 259 (moderate), and a light cross-offshore breeze from the south-southeast at only 6 mph. Conditions will be clean, the wave shape will be okay for a river break that’s fairly exposed to the west-northwest. The crowds are listed as “sometimes,” so you might have a few out, but nothing crazy. It’s not a big-wave day, but it’s the best we’ve got – a fun, clean little session.

After that, Thursday the 23rd and Friday the 24th slide back into onshore slop and poor surf. Saturday the 25th shows a 6ft west swell with a 9-second period and strong energy at 503, but the wind is cross-onshore and choppy again. Not clean enough to make it worthwhile for paddle surfing.

So here’s the bottom line: if you’re keen, aim for Wednesday morning the 22nd. That’s the only real window where things line up. The rest of the month is either flat, windy, or both. But hey, it tends not to stay poor forever – forecasts can change.

Rusty, signing off.
