Alright, Rusty here, let’s talk about what’s cookin’ for Mawgan Porth.

Right off the bat, I gotta be straight with you – this forecast is a bit of a heartbreaker. The next couple of weeks are looking pretty flat and messy, with no real standouts for a proper surf. We’ve got a long dry spell ahead.

Right now, Friday afternoon, you’d be lucky to find a rideable 3 ft wave from the west (128 energy). It’s clean enough, but cross-off from the NE at 6 mph, and the water’s a touch warmer than normal at 63°F. It’s surfable but very ordinary, not worth getting excited about.

Saturday morning sees the swell drop to a tiny 1 ft from the WNW, and while the wind is offshore, it’s not enough to make anything decent. Saturday afternoon is similar – 2 ft from the west (90 energy) – same lackluster story. Sunday and Monday are a dead loss; we’re talking small 1 ft to 2 ft swells with moderate offshore winds, but the energy is pathetic (23 to 52 energy). Just not worth paddling out for.

Tuesday and Wednesday stay tiny, with a brief moment of interest Tuesday afternoon – a 0.7 ft swell from the WSW but with a very long 18-second period. That’s a true groundswell, but the size is just too small to do anything with. It’s a clean day though, with a slight offshore breeze from the ESE.

From Thursday, July 16, through to the following Wednesday, July 22, it’s a real grind. Lots of cross-onshore and cross-shore winds, lumpy chop, and surging energy that’s still under 4 ft until the 19th. On Sunday July 19, the swell bumps to 4 ft from the north (135 energy) but the cross-off wind is a brisk 16 mph – not the cleanest. It stays messy, with the 20th and 21st offering similar small stuff.

Now, things start looking a bit more interesting from Wednesday, July 22. The swell picks up to 6 ft from the WNW (360 energy) with a strong N cross-off wind – the sets will be there, but that fresh wind is going to mess with the surface. The 23rd has a cleaner 5 ft swell from the west, but it’s still only a marginal call.

The real kicker is the end of the run: Friday, July 24. We’ve got a massive 13 ft to 15 ft swell from the west, with a 10-12 second period and clean cross-off winds from the SE. The combined energy is a huge 3402 to 5203! The problem is, that’s way too big for Mawgan Porth – this is only for experts, and even then, the river mouth might be a washing machine. Saturday July 25 looks oversize and onshore.

So, the only true standout, if you’re an expert and you’re brave, is Friday July 24. The swell direction (W) is spot on for the optimum WNW, and the wind is clean. But honestly, the size is a beast.

For everyone else, this is a two-week write-off. There’s a big gap until that last Friday, and even then, it’s not for the faint-hearted.

Rusty.
