Mawgan Porth Surf Forecast and Surf Report

Right then, let's have a look at what's on the cards for Mawgan Porth. To be straight with you, it's a bit of a tough watch for the next week and a half or so. The winds are mostly cross-on or onshore, with a lot of lumpy chop and messy conditions. For a river break that's fairly exposed, we need the wind to play nice, and for a long stretch here, it's just not happening.

We kick off on Thursday the 10th of September, with a 7ft swell out of the west, but that's getting battered by a 35 km/h cross-on southwesterly. The combined energy is moderate at 501, but the wave comment says it all: poor surf. That theme carries on through Friday, Saturday, and into Sunday. There's a bit of a pulse on Sunday the 13th with a 5ft west swell and a 10-second period, giving us a combined energy of 450 (moderate), and the wind swings onshore, but it's still labelled poor. It's a real grind.

The wind doesn't let up into the second week either. We see some pulsey energy, like on Tuesday the 15th with a 7ft swell from the west-northwest, but it's short-period at 7 seconds and being torn up by a fresh 30 km/h cross-on wind. For a spot that can handle a bit of size as a river break, the conditions are just too wild. This pattern of fresh cross-onshore and lumpy persists right through until the 21st.

Now, here’s where it gets interesting. Hold on for the 22nd of September. Tuesday morning sees the wind finally drop right out, turning to a light cross-offshore breeze from the east-northeast at just 5 km/h. The swell is a modest 3ft from the west with a 9-second period, but the wave comment shifts to "surfable waves but very ordinary conditions," and the wind state is "clean." The combined energy is weak at 187, but for a break that's been getting smashed, this is a moment of calm. It's not going to set the world on fire, but it's a paddle.

But the real standout, the one you've been waiting for, is Wednesday the 23rd of September. Wednesday morning we've got a 8ft west-northwest swell, cross-off wind from the southeast at 5 km/h, and the wave comment is "expect very good surf conditions." The combined energy jumps to 689, which is strong. Then Wednesday afternoon, it really cooks: a 10ft west swell, light cross-off wind, and "excellent surf conditions for experienced surfers" with a combined energy of 1462 (very strong). That's a proper pulse. The water temperature is 65°F, which is much warmer than normal for this time of year, so the rubber might be a little thinner.

The 24th of September keeps the clean conditions with cross-off winds, but the swell drops a bit and the forecast gets a little more questionable with the tide. It'll be surfable, but Wednesday the 23rd is the day to circle.

Remember, this is a river break, so that long-period groundswell on the 23rd (10 seconds) will hold up nicely in the river mouth. For beginners, that 10ft on the 23rd afternoon is going to be a handful; that's expert territory.

So, a long, dry spell of poor conditions, but a light at the end of the tunnel with a proper clean, powerful swell on the 23rd.

Rusty.
