The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Mawgan Porth. I’ve gotta be honest with you, looking at the next couple of weeks, it’s a tough stretch. The good news is there are a few windows where you might get a wet sock on, but overall, the ocean’s not playing ball.
We kick things off with a real flat spell. Most of this week and the start of next is a write-off, with weak swell and messy winds. The only flicker of hope shows up on Thursday the 23rd morning. The wind goes dead calm – glassy – and there’s a weak 3ft swell from the NNW with a short 6-second period. The combined energy is weak (67), but for a river break like Mawgan Porth, that glassy morning will be your best chance for a few grovelly ones. The water temp is sitting about average for the time of year.
After that, it’s back to poor surf conditions with a cross-chop or onshore wind for days. Honestly, it’s a proper dry spell through to the end of July.
Now, hold on. The outlook changes a bit as we get into the start of August. On Sunday the 2nd of August, we’ve got a small 2ft swell from the west with a 9-second period, but it's accompanied by a gentle cross-onshore breeze, so it'll be fairly choppy. Then on Monday the 3rd of August, the swell bumps up to 3ft from the west (10-second period) and the combined energy climbs to 143 (moderate). Unfortunately, it’s a straight onshore wind from the west, so those waves will be messy and blown out. Still, it’s the most energy we’ve seen in a while.
The standout – and I use that term loosely – is actually that glassy Thursday morning on the 23rd. Flukey conditions, but it’s the only time you’ll find truly clean, rideable waves. If you’re desperate for a surf before then, you might be better off waiting for a change in the forecast.
This is Rusty, signing off.
