The Lowdown
Right then, let’s have a look at what’s on offer for Mawgan Porth over the next couple of weeks.
Honestly, it’s a pretty grim stretch for the paddle crew. There’s nothing that jumps out as a proper surf session for the whole 16-day window. The forecast keeps throwing up poor surf conditions day after day, with only a few fleeting moments of surfable but very ordinary waves. The water temperature is sitting at 65°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing while you’re sitting there waiting for a wave that never really comes.
The first few days, Sunday the 23rd and Monday the 24th, are tiny. We’re looking at a mere 0.7 ft to 1 ft of swell, with a short period around 13 to 14 seconds, and the combined wave energy is a weak 42 to 66. The wind is cross-off or offshore, which is clean, but there’s just no power behind it. Tuesday the 25th isn’t much better, with a 2 ft to 2 ft swell from the west, period dropping to 10 seconds, and the energy still low at 60 to 86.
By Thursday the 27th, the swell bumps up a bit - 4 ft from the SSW with a period of 8 seconds and energy climbing to 206 (moderate). But the wind is straight cross-shore and then cross-onshore, which will make it a choppy, lumpy mess. That’s the story for the rest of the week, really. On Saturday the 29th, the swell jumps to 8 ft from the west, with strong energy of 816, but it’s a full-on, 22 mph onshore gale. That’s serious, stormy, blown-out junk. That’s kite-surf territory, not a paddle surfer’s dream.
The first week of September doesn’t offer any relief. There’s a bit of a spike on the 6th of September - Sunday morning - with a 5 ft swell from the west, period at 7 seconds, and energy of 336 (moderate to strong). The wind is cross-off from the SSE at 22 mph, so it will be clean on the face. But the period is short, so it’ll be a bit of a messy, lumpy wave. It’s the most promising of a very poor bunch, but that’s not saying much. For a brief window, it might be the best on offer for a competent surfer, but it’s still a long way from good.
There’s a gap of several days with no real recommendations, and the long-range stuff out to the 7th of September is just more of the same - small, weak, or blown out. The whole period is a write-off, really. It’s one of those blank runs that’s more normal for the area, but forecasts can change, so keep an eye on it.
