Table - best surf conditions forecast for Mawgan Porth over the next 16 days.
Alright, Rusty here again, switching to the old-school numbers. Let's be honest, Mawgan Porth is in a bit of a lull. The next week and a half is mostly flat and a mess, with just a few little windows that might be worth a splash.
The first real chance to get a wave is Friday morning, July 10th. We’ve got a small 3 ft swell from the west, with a 9-second period. The wind is light and cross-offshore from the NNE, keeping the surface clean. It’s not going to be pumping, but it’s rideable. The wave energy is weak (136), so don't expect any power. This is a beginner-friendly spot, and with the clean conditions, it’s your best bet in the first week.
Saturday morning, July 11th, is a similar story. The swell is a bit smaller, around 2 ft from the west, with a 10-second period. The wind is still light and cross-offshore, keeping it tidy. Again, weak energy (101). A small, clean wave for the longboard.
Sunday morning, July 12th, the wind shifts. A moderate offshore breeze from the east at 15 mph cleans up the face, but the swell is tiny at 3 ft from the north, with a short period of 6 seconds. The energy is very weak (64). It’s clean, but it’s going to be a fight for any kind of ride.
Then we hit a massive dry spell. From Monday, July 13th, all the way through to Wednesday, July 23rd, the surf is either flat or blown out. The wind is either howling onshore, or the swell is too small and weak. That’s a solid 10-day stretch of poor surf, so don't bother.
Now, the end of the forecast is where it gets interesting. Friday morning, July 24th, we get a pulse. A 6 ft swell from the WNW, but with a short period of 6 seconds. The energy is moderate (242). The big news is the wind – it’s glassy. Dead calm. This will be the cleanest surf of the whole outlook. But, that 6 ft swell on a short period can be a bit of a handful for beginners at this river break, and it’ll be a bit walled up. If you’re an experienced surfer, put that Friday morning on your calendar. It’s the standout, but it’s a long way off, so keep your hopes up.
Rusty, signing off.
