The Lowdown
Right, grab a coffee, let’s talk about Mawgan Porth. I’ve looked at the next few weeks and, honestly, it’s a pretty bleak run for us paddle surfers. There’s a big gap of nothing worth mentioning right at the start.
The first real chance to even think about a wave doesn’t come until Wednesday, August 12th. That’s over a week of waiting. The setup there is a small, weak swell with a period of 11 seconds, which is a long period groundswell for a river break. The combined energy is only 62 (weak), and it’s a piddly 2ft from the west. The wind is offshore from the east, so it’ll be clean, but the wave comment says it’s "surfable waves but very ordinary conditions." That’s the best we get, and it’s a struggle.
For the rest of the window, it’s a mess. You’ve got some moderate energy days, like the morning of August 5th with a 7ft swell from the west and a combined energy of 434 (moderate), but the wind is howling 19 mph onshore, so it’s blown out. On August 13th, there’s a similar story: 4ft swell from the west and 239 combined energy, but again, onshore wind. The period is short (8 seconds), so it’s just a lumpy, weak windswell.
The water temperature is sitting at 65°F, which is a touch warmer than normal for this time of year, but that’s the only bit of good news. The wind is almost always cross or onshore, keeping things choppy and messy. There’s nothing here for a beginner, and even the bigger days are poor quality. For a river break, this long period swell on the 12th might actually break a bit too straight. Honestly, if you’re desperate, that morning of August 12th is your only shot, but don’t expect much. For the rest of it, this setup looks more interesting for kite surfing than paddle surfing.
