Mawgan Porth Surf Forecast and Surf Report

Alright, let’s break down what’s happening at Mawgan Porth over the next couple of weeks. It’s a bit of a strange one, honestly. There’s a lot of junky surf to start, then a clean little window, and then it just sort of switches off.

For the first stretch from the 15th through the 20th, it’s rough. Swell is there, in the 5 to 7 foot range on the face, but the wind is on it or cross-onshore, making it lumpy and messy. The energy is moderate stuff – you’re seeing numbers like 407 and 936 – but it doesn’t matter because the surface is blown out. Not worth paddling out for a beating.

Things get a whole lot better on Monday the 21st. The swell drops to around 3 feet, but we finally get that clean, glassy morning. The wind goes light and variable, and the energy reading is weak at 235, so it’s not big, but it’s clean and surfable. A nice little change of pace for the river mouth.

Tuesday the 22nd is similar, but the afternoon gets a bit of a cross-shore bump.

Now, circle Wednesday the 23rd. This is the one to get excited about. The morning shows 1.3m – that’s around 4 to 5 feet – from the WNW with a 14-second period. That’s proper groundswell, with a strong energy rating of 867. And the wind is glassy. This is the best-looking clean surf of the whole forecast. The river mouth is going to be the spot, and long-period swells work well there. It’ll have some real push to it.

The afternoon of that day is bigger, with waves around 6 feet and energy up at 1058, but the wind goes a little cross, so the morning is your best bet.

Thursday and Friday are still okay, with waves in the 3 to 4 foot range. They’re clean with light offshore winds, but the energy drops down to 339 and 609. Good for the log, not for any heavy stuff.

And then, it just fades. From Saturday the 26th onwards, it gets smaller and weaker. Swell drops, energy readings crater – you’re looking at 206, then 51, then 35. The wind turns strong from the ESE, keeping it clean, but there’s just no swell. It’s flat. There’s a minor bump on the 30th with some 5 foot waves and a clean offshore wind, but the energy is only 419, so it’s a marginal, short-lived pulse.

So, the standout is the morning of the 23rd. Everything aligns – the size, the period, the wind. Don’t sleep on it. The water temp is pretty standard for this time of year, nothing to worry about.

Rusty out.
