The Lowdown
Alright, let’s talk about Mawgan Porth (United Kingdom).
Honestly, mate, it’s a pretty grim run for the next couple of weeks. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, so at least the water’s nice. But the surf? It’s a mess. The first few days are basically a write-off. Wednesday afternoon the 26th has tiny 2 ft swell from the west, weak energy (42), and a cross-off wind, but it’s just too small to do anything with. Thursday and Friday are similar – small, weak, and messy with wind all over the place. The swell starts to show a bit of life on Friday the 28th morning with 7 ft from the west-southwest, but it’s short-period (6 seconds) and choppy. That kind of short-period windswell is junky, and with a strong cross-onshore wind, it’s not worth paddling out for.
The weekend of the 29th and 30th sees the swell bump up – 7 ft from the west-southwest on Saturday afternoon, with moderate energy (794), but it’s onshore and messy. Sunday is similar with 6 ft but cross-onshore and lumpy. The wind is strong, and the quality is poor. This is the kind of setup that might be more interesting for kite surfing than paddle surfing, to be honest.
Things get bigger but not better. Monday the 31st morning has a 10 ft west swell with long-period (10 seconds) and very strong energy (1484), but it’s cross-onshore and choppy. That’s expert-only territory, and it’s not clean. The whole first week is a write-off for good surf. There’s a long gap of days with no real recommendations.
The only glimmer comes early in the second week. On Saturday the 5th of September morning, we get 6 ft from the west (8 seconds, moderate energy 364) with a light onshore wind – it’s marginal. Then Saturday afternoon the swell holds at 7 ft, energy 510, and the wind is light cross-onshore from the north-northwest. Still only marginal. But Sunday the 6th of September morning is the standout. The swell is 6 ft from the west, period 10 seconds (a nice long groundswell), energy 518, and the wind is cross-off from the southeast. That’s clean. The only catch – this is a river break, so a long-period swell might break a bit straight, but with cross-off wind it should be workable. It’s the best call in the whole 16 days, but it’s far out, so treat it as promising but not locked in. Crowds are possible at this spot.
So, if you’re desperate, keep an eye on that Sunday the 6th morning. Otherwise, it’s a long wait for anything decent.
