Mawgan Porth Surf Forecast and Surf Report

Alright, Rusty here, and I’ve got the outlook for Mawgan Porth for the next couple of weeks, and I’ll be straight with you – it’s a tough one to call, and the surf just isn’t playing ball. The combined wave energy is weak to moderate at best, and the conditions just keep letting us down. We’re looking at a solid run of poor surf all the way through.

Starting on Saturday the 12th, the swell is 6 ft from the W, but it’s pulsing with only 400 energy and is a short period 8 second affair. But the real killer is that 19 mph SW wind smashing across the face, making it a lumpy mess. We see some water temps around 64°, which is a touch warmer than normal for this time of year at Mawgan Porth. This is a windswell mess, best left for another day.

By Sunday morning the 13th, the swell drops to 5 ft from the W, period picks up a bit to 10 seconds, but it's still moderate cross-onshore and choppy. The afternoon is the same story with 5 ft waves. This pattern just keeps rolling. Monday the 14th sees the size drop under 5 ft, which is a better size, but the cross-onshore wind and the “poor surf conditions” tag don't budge.

We stay stuck in this loop right through the first week. On the 18th of September, Friday morning, we have a last gasp of swell at 5 ft from the WNW with a very long period of 13 seconds, giving us a strong 795 energy reading, but it’s onshore and the conditions are still poor. That long period groundswell would be better at a point or reef, not this setup. Saturday the 19th still has onshores and lumpy conditions.

There’s a bit of a reprieve on Sunday the 21st of September morning with the wind easing to only 3 mph from the NW, but the swell has dropped right off to 4 ft, and it’s still cross-onshore with small wind ripples. Not worth paddling out for.

From Monday the 22nd onwards, we’re looking at a real gap. The swell just dies away, falling to 2 ft, then 1.0 ft. There are days of nothing. The combined swell energy drops to double digits, a weak 64 or lower. There’s a stretch from the 22nd through to the 27th where the wave height barely nudges 2 ft. One bright spot on the 24th and 25th is some clean offshore winds from the SE, but there’s no swell to work with – just 1 ft and 2 ft. It’s glassy and clean, but flat.

Do I have a standout? There is no standout. I can’t point to a single session that’s going to deliver. This is one of those blank runs where the area just isn’t getting any love from the ocean. The forecasts can change, but right now, I’d say save the petrol and wait for the next system.

- Rusty.
