Mawgan Porth Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what Mawgan Porth has on offer.

Honestly, it’s a bit of a rough start. The first few days are a write-off with messy, choppy conditions and onshore winds ruining any shape. Thursday the 3rd and Friday the 4th are plagued by moderate to fresh cross-onshore winds and lumpy surf. The wave energy is moderate at 284 and 258, but it’s not worth paddling out.

Then, things take a turn for the better. Saturday the 5th is your standout window. We’ve got a clean, glassy morning with light winds from the WSW, and a solid 4.6ft swell from the WNW with a nice 11-second period. This is groundswell energy with moderate power (476), and with the glassy conditions, the river mouth and beach setup at Mawgan Porth should offer some clean, fun little lines. It’s not big, but for a beginner-friendly spot that’s fairly consistent and sometimes crowded, this is about as good as it gets in this outlook. The afternoon stays glassy with 3.9ft – a real treat.

Sunday the 6th drops right off to 2.0ft and weak energy (64), so don’t bother. Monday the 7th and Tuesday the 8th see a big jump in size – 7.2ft to 9.8ft – but the wind is onshore or cross-onshore and strong, making it a choppy mess. That 9.8ft on Tuesday morning is very strong energy (1299), but with fresh onshore wind, it’s an expert-only zone and not appealing.

Wednesday the 9th through to the end of the first week is a mix of poor cross-shore winds and weak or messy swell. The 11th and 12th have some 6.9ft and 6.2ft swell, but strong cross-winds make it lumpy. Nothing worth getting excited about.

There’s a gap of a few days in the middle with no real recommendations. The next flicker of hope comes on Monday the 14th and Tuesday the 15th of September. On Monday morning, we get 3.3ft of swell from the west with a 9-second period and light ESE winds that are cross-offshore. The conditions are clean, energy is low (152), but it’s surfable. Tuesday morning is a bit better – 3.3ft swell, 10-second period (261 energy), and glassy conditions with a light easterly. The water temp anomaly is about average for this time of year. These are worth a look for a peaceful session.

Wednesday the 16th offers a tiny 3.9ft swell from the north with a short 6-second period – glassy air but it’s weak (154) and a bit of a novelty. After that, the swell dies to 1.3ft and 1.0ft through to the 18th. The long-range outlook is pretty bare.

Overall, the best bet is definitely Saturday the 5th – glassy, clean, and a nice groundswell. The second-best shout is Tuesday the 15th morning for a glassy, ordinary but clean session.
