Table - best surf conditions forecast for Mawgan Porth over the next 16 days.
Alright, let’s look at what’s brewing for Mawgan Porth over the next couple of weeks.
Honestly, it’s a pretty bleak run for the most part. The forecast is stuffed with poor surf conditions and only a few fleeting moments where it’s even worth paddling out. The first real window of opportunity is about four days away, on Thursday the 9th of July. The water temp is sitting at 63°, which feels a touch warmer than normal for this time of year. That’s a small comfort.
Thursday morning at Mawgan Porth is the best of a very average bunch. We’ve got a clean 3ft swell rolling in from the WNW with a period of 10 seconds, and a light cross-off breeze from the north at 6 mph. The combined energy is moderate (126). It’s surfable, but it’s nothing to write home about. The real standout, though, is Friday morning the 10th. Glassy conditions, with the wind dropping to a slight air from the NNE at just 3 mph. The swell is a touch bigger at 3ft, coming from the west with a 9-second period, and the energy is moderate (136). That’s your cleanest, most inviting session of the entire forecast. It’s small, but it’ll be a joy if you’re on a longboard or a foamie. The water is still that touch warmer than usual.
After that, it’s a long, dry spell. From Saturday the 11th right through to the end of the 16-day window, it’s essentially all poor surf. The swell drops to nothing, the wind turns onshore and cross-shore, and the combined energy figures are mostly weak, dropping into the 20s and 30s. There’s a brief uptick in energy on the 19th of July (Sunday morning) with a 2ft west swell and 8-second period, but it’s still small and the wind is cross-off. It’s a paddler’s dream for a bit of exercise, but not for waves. After that, the week of the 21st to the 24th sees a slight increase in swell height, but the wind is all cross and cross-on, making for choppy, lumpy conditions. Nothing worth chasing.
So, to put it bluntly: the only real highlight is Friday morning, the 10th of July. Tiny, glassy, clean. That’s your best bet. Everything else is a write-off. If you’re desperate, the 19th of July morning might give you a few knee-high dribblers, but don’t hold your breath.
