The Lowdown

Right, grab a cuppa and let’s have a look at what’s coming up for Mawgan Porth over the next couple of weeks. I’ll be straight with you, mate—this one’s a bit of a slow burner, with a long, frustrating gap of rough conditions before we finally see some clean lines appear.

The first week and a bit is a write-off, honestly. From Tuesday the 8th right through to Monday the 14th, it’s all poor surf conditions with lumpy cross-onshore winds and messy chop. We’ve got a few pulses of waist-to-chest high swell (about 5 to 7 feet) on the 8th and 9th, but with a stiff cross-onshore breeze, it’s going to be a bumpy, blown-out mess. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, but you won’t be in the water long enough to notice. The combined swell energy is moderate (639) on Tuesday morning, but the wave comment says it all—poor.

We then hit a long, flat spell of weak energy, with a couple of small, grovelly days around the 10th and 11th, but still with cross-shore wind. Even the 13th and 14th, though the wind flicks onshore, the swell is small and the quality terrible. Honestly, it’s more of a kite-surfing setup than paddle surfing out there with those strong cross-shore winds.

The real story starts to shift around Friday the 18th. We finally see the wind clock around offshore—light east-sou’east breezes—and the wave comment changes to “surfable but very ordinary.” The swell is small, only about 3 feet from the WNW, but it’s clean. Energy is weak (116), so don’t expect much push, but the shape will be there for a log.

Now, hold on to your wetsuit, because Tuesday the 22nd is the standout. Through the morning and afternoon, we get a moderate offshore breeze from the east, a waist-high swell of about 4 feet from the west with a decent 11-second period, and combined energy jumping up to 444—moderate but with proper punch. The wave comment says “expect good surf conditions,” and at this sight, that’s gold. The direction matches the optimum WNW swell direction perfectly, and with that offshore wind, it’ll be glassy, clean, and peeling nicely. Crowds are listed as “sometimes,” so you might have a few mates out, but it’s a river break, so it handles a few bodies. This is your window.

The following morning, Wednesday the 23rd, still offers good quality but with a fresher 19 mph offshore wind, pushing the swell to about 4 feet and a longer 12-second period. The energy is strong (469), but that fresh wind might make it a little tricky to read.

So, here’s the bottom line: don’t bother paddling out until Friday the 18th at the earliest, but the real pick of the fortnight is Tuesday the 22nd. Clean, waist-high, and offshore—that’s the one to circle on the calendar.

Rusty.
