The Lowdown

Alright folks, Rusty here. Let’s have a look at what Mawgan Porth has in store over the next couple of weeks. I gotta be straight with you – this is a tough stretch. The data shows nothing but poor surf conditions across the whole 16-day window, so there’s no standout day or session to get excited about. We’re looking at a real dry spell.

The first hint of any rideable swell doesn’t even show up until August 12th, and even then it’s messy. Before that, from the 6th right through to the 11th, we’ve got tiny, weak waves. Expect heights under 2ft, mostly from the west, with periods around 6 to 9 seconds. The combined wave energy is weak, sitting in the double digits (between 13 and 54) – limp and lifeless. Winds are all over the place, mostly cross or cross-on, keeping things choppy and unappealing. There’s a brief moment on August 8th Saturday afternoon with glassy conditions (ESE 0 mph), but the swell is a pathetic 0.7ft, so it’s a flat calm, not a surfable one.

Around August 12th, things try to pick up. We see a bit more size, with swell heights reaching 4ft to 4ft from the west, and the period stretches to 10 seconds – that’s a bit more groundswell character. The combined energy jumps into the low-to-mid 200s (225 to 290), so there’s some moderate energy in the water. But the problem is the wind. We’ve got cross-on breezes from the NW and WNW at 6-9 mph, making for a choppy, bumpy surface. The conditions are marked as poor across the board, so the quality just isn’t there for a good session.

The second week rolls in with similar problems. From August 14th onwards, we see waves in that 2ft to 4ft range, with periods mostly short (6-8 seconds) and occasionally longer (10 seconds on the 20th and 21st). On August 20th Thursday, we get an energy reading as high as 341, the strongest of the whole period, with a 10-second period from the west-northwest. But again, the wind is a deal-breaker – fresh cross-onshore breezes at 12-19 mph, making it lumpy and rough. It’s a consistent pattern of “almost” but never coming together.

Given the persistent cross-on winds, decent energy levels, and the fact this is a river break that’s fairly exposed, the setup here might actually look better for kite surfing than traditional paddle surfing, especially on those days with moderate energy and stronger winds.

Overall, this is a lean forecast. For the entire 16 days, there is not a single recommendation to highlight. The area is just stuck in a rut of poor surf quality.

Let’s talk water temps. For Mawgan Porth, the water is sitting at 66°F on August 6th, which is a touch warmer than normal for this time of year (anomaly of 3°F). Comfortable enough for a shortie.

That’s all I’ve got for now. Keep an eye on the charts; things can shift.

Rusty.
