Mawgan Porth Surf Forecast and Surf Report

Right on, let’s get into it for the next couple of weeks here at Mawgan Porth. Honestly, it’s a pretty bleak stretch of surf ahead, so temper your expectations.

We’ve got a bit of a nothing burger to start. The first day or two, you’re looking at tiny, weak waves. Sunday morning the 23rd has a tiny 0.7ft dribbler with a WSW direction and not much period, but it’s clean with light winds from the ENE. The combined wave energy is weak at 43. Water temp is sittin’ at a touch warmer than normal for this time of year at 65°, so that’s a small win. But really, it’s just not worth paddling out unless you’re on a longboard for a splash.

There’s a big gap where there’s almost nothing surfable. From Monday the 24th through to the end of the month, conditions are poor. You’ll see a lot of onshore or cross-offshore winds, generally clean but with hardly any swell. The energy is low, often below 100. You’d be chasing shadows.

Towards the end of the first week, we see a slight bump. Thursday the 27th morning has a small 4ft swell from the southwest, period only 7 seconds, but the wind is southerly cross-shore. It’s enough to make it look a little bumpy, but the combined energy is only moderate at 174. Still not worth the hype, though.

The second week gets a little bigger, but the wind is filthy. Saturday the 29th has 8ft of west swell at 8 seconds, and the wind is a strong cross-onshore from the WSW. That’s a lot of power with a combined energy of 970, but it’s lumpy and blown-out, just a mess. That trend holds right through to the end of the forecast. There’s a window around Friday the 4th of September where we see 8ft of west swell at 10 seconds, which is a bit more period, and combined energy is strong at 1223. Winds are light from the SSW, cross-shore, so it’s the least junky of the bigger stuff, but honestly it’s still just marginal. It’s a beach-and-river setup here, and with that short-ish period (10 seconds is decent but not groundswell territory) and not the right direction, it’s not the kind of wave that’s going to hold its shape well. It’s more of a kite-surfing slop than a solid paddle session.

The last few days, the swell just gets bigger and more unruly. Monday the 7th of September has 12ft of west swell with 10-second period and a combined energy of 2899, but with 31 mph onshore winds from the west it’s a full-on washing machine. Experts only, and even then, it’s a battle.

If there’s one standout – and I’m stretching it – it’s that Friday the 4th of September. The swell is big enough (8ft), period is a touch better at 10 seconds, light cross-shore winds, but it’s still only a marginal setup. Consider it a promise, but don’t hold out for the best session of your life. The rest of this run? Honestly, the blank spots are there for a reason. This area tends to get long quiet spells, and this is one of them. Forecasts can always change, so don’t write it off completely, but for now, leave the board in the van.

Rusty.
