The Lowdown

Right then, let’s have a look at what’s on the cards for the next couple of weeks. Honestly, it’s a pretty quiet stretch for Mawgan Porth. The river mouth setup here is a beginner’s spot, and it’s been fairly flat and gutless for the first week. The water’s running a touch warmer than normal, sitting at 64°, so that’s a nice upside if you’re just having a paddle.

We’ve got a long gap of nothing worth paddling out for. From Saturday the 18th right through until the morning of Monday the 27th, there’s just no real surf to speak of – tiny dribbles, short period, mostly cross or onshore wind. Not worth the wetsuit. The wind is mostly from the north or northwest, which is fine for the offshore direction here, but there’s nothing but a ripple to work with.

Then, on Monday the 27th of July, things start to wake up. We see a jump in swell to 5 ft from the west, with a period of 7 seconds. The combined energy climbs into the moderate range (239 to 247). Problem is, the wind is onshore from the west, so it’ll be a bit bumpy. It’s still poor surf conditions according to the local knowledge, so keep your expectations low.

By Tuesday the 28th, the swell holds around 5 ft to 5 ft from the west, period creeping up to 9 seconds, and the energy is getting stronger (335). The wind switches to a cross-shore from the north or north-northwest, which is a decent call. The wave comment says it’s poor surf conditions, but that’s where the best of the run sits. For a beginner spot, this is about as good as it’ll get in this window.

Wednesday the 29th through to Friday the 31st sees a building swell, actually hitting 8 ft on the Friday morning from the west-northwest, with a period of 8 seconds and strong combined energy (671). That’s getting into the too-big-for-beginners territory. The wind stays onshore from the west, so expect a messy, choppy surface. It’s really only for the experienced crew, and even then, it’s not clean.

The first weekend of August, the 1st and 2nd, the swell drops back to 4 ft to 5 ft, but the wind is still onshore or cross-onshore from the west and southwest, keeping things chopped up. The energy is still moderate to strong (264 to 605), but the quality is poor.

Honestly, for the whole 16-day outlook, there’s no standout session. The best bet would be the morning of the 28th of July if you’re desperate for a wave, but don’t expect a classic. It’s one of those runs where the forecasts can change, but for now, it’s a tough call to get excited about.
