The Lowdown
Right then, let’s have a look at what’s on offer for Mawgan Porth.
Honestly, it’s a grim stretch ahead. The next two weeks are looking pretty flat and messy, and I’d be hard-pressed to call any of it a proper surf. There’s a real gap of poor conditions here, with no real standout session to get excited about for the entire 16-day window. The first few days are just not worth paddling out for, with tiny, weak waves and bad wind angles.
The water is sitting at 64°, which is a touch warmer than normal for this time of year, but that’s about the only positive.
We do see a little bump in wave energy on the 25th of July, with a combined swell energy of 135 (moderate), but it’s accompanied by a strong cross-onshore wind from the NW at 15 mph, making it choppy and poor. The swell is 4 ft from the west at a short period of 6 seconds – that’s just windswell, and it’ll be a mess. It’s not ideal for a paddle; you’d be better off looking at a kite if you’re into that. The same goes for the 26th, with onshore winds and a swollen 4 ft from the west; it’s not for surfing.
The only sliver of a chance comes on the 21st of July in the morning. We get a clean, offshore wind from the ENE at 9 mph, and a tiny 1 ft from the WNW, but with a 10-second period it’ll have a bit of shape. The combined energy is only 54 though, so it’s weak. The conditions are described as “surfable waves but very ordinary,” and I’d say that’s being generous. That’s your best bet, and it’s not saying much. The river mouth might offer a tiny bank, but it’s a beginner spot and crowds are possible, so don’t expect much space.
The rest of the period is a write-off – mostly cross-shore or onshore winds, tiny heights, and short periods. The 30th and 31st see a jump in energy (145 and 184), but with fresh cross-shore winds and short periods, it’ll be lumpy and unappealing.
So, in short: there’s very little to get excited about. The 21st morning is your only real chance at a clean, small wave, but it’s not going to be a memorable session. The forecast can always change, but for now, I’d leave the board in the car.
