The Lowdown
Alright, Rusty here. Let's have a look at what's on the menu for Mawgan Porth.
Honestly, it's a pretty bleak run for the next couple of weeks. There's a tiny window of something rideable right at the start, but after that, we're looking at a long stretch of flat, choppy, or just plain messy conditions. The river mouth is the only spot in the game here, and it's not exactly firing.
First up, we have a brief moment on Monday morning, the 3rd of August. It's small, with waves around 3 ft coming from the WSW. The swell energy is pretty weak (99), and the period is a middling 9 seconds. The wind is a light SSE cross-off, so it'll be clean. The water is a touch warmer than normal at 65°, but honestly, it's just surfable, nothing special. That afternoon, the wind drops to glassy, but the swell drops too, to 2 ft. It's a tough call, but if you're desperate, that Monday afternoon glass-off might be the cleanest, most user-friendly wave of the whole 16-day window. It's a very quiet standout.
Then, from Tuesday the 4th onwards, it goes south. The wind picks up strong from the SW, smashing the little 3 ft swell into a choppy mess. By Wednesday the 5th, we get a pulse of 7 ft swell from the west, but it's accompanied by strong onshore winds. The combined energy jumps to 453 (moderate), but the quality is poor. That size is getting too big for beginners anyway, and with the wind, it's a washing machine. For a river break, this setup is honestly more interesting for kite surfing than paddle surfing.
The entire rest of the forecast through to the 18th of August is just a run of tiny, weak swells, or onshore winds. There are days with practically no energy at all. Take the 12th of August, for example: 1.0 ft swell with a 10-second period, but cross-on wind. It's just not worth it. The consistency is "fairly consistent" here, which usually means it's not a dead zone, but this forecast is about as blank as it gets. It's one of those periods where you just have to accept the lull; forecasts can change, but for now, there's nothing to get excited about.
Rusty, signing off.
