Mawgan Porth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be honest about what’s on offer for Mawgan Porth over the next 16 days. It’s a pretty grim outlook for a paddle surfer, so I’ll tell you straight.

The first hint of any surfable wave doesn’t show up until Tuesday afternoon, the 14th of July. Before that, the swell is tiny and weak, and the energy is just not there. That first session on Tuesday afternoon is tiny though, with a swell of just 0.7 ft coming from the WSW. The period is a massive 18 seconds, which is a very long period groundswell, but for a river break like this, that long period tends to make waves break too straight. The only saving grace is that it’s glassy—dead calm wind. The water temp is a notable 66°F, which is much warmer than normal for this time of year. The combined energy is weak (71).

Wednesday morning, the 15th, is a bit better. Swell is still only 1 ft from the W, with a period of 9 seconds, and the wind is a light cross-offshore breeze. It’s clean, but still very small and ordinary. The energy is weak (54). After that, we hit a long dry spell. From Wednesday afternoon right through until the 22nd of July, the waves are all under 2 ft, the wind is messy, and the scores are all zeros. It’s just poor conditions day after day. There’s a gap of nearly a week of nothing worth mentioning.

The one standout in the whole forecast is on Wednesday the 22nd of July. The morning and afternoon both show 2 ft of swell from the west, with a period of 9 seconds. The wind is glassy—dead calm in the morning, and just a slight air in the afternoon. That’s the cleanest we’ll see it. The combined energy is still only moderate (66 and 65), but with the river mouth setup and glassy conditions, it’ll be the best chance for a fun, small-wave session. The swell direction is from the west, which is a good match for the break’s optimum WNW direction. Beginners will be fine in this size.

After that, the weather turns ugly. By Thursday the 23rd, the wind picks up strong from the SE, and then from the 24th onward, we get onshore winds and a building, choppy swell. The swell gets bigger, hitting 5 ft on the 25th, but the wind is onshore and the period is short (7 seconds). The energy gets moderate (183), but the quality is terrible. The 26th and 27th bring strong winds and rain, making it a complete washout for surfing. Honestly, for the last few days of the month, the setup looks more interesting for kite surfing than paddle surfing, with that strong cross and cross-onshore wind.

So, bottom line: if you’re desperate for a surf, target the 22nd of July for the best chance of a clean, glassy session. The rest is a write-off. Don’t hold your breath.

Rusty.
