The Lowdown

Alright, Rusty here, let’s take a look at the outlook for Mawgan Porth.

Well, I’m not gonna lie to ya, it’s a bit of a tough stretch ahead. This ain’t gonna be a week for surfing glory. The next seven or eight days are pretty much a write-off, with sloppy conditions and onshore winds messing up whatever swell is in the water. You’re looking at small, weak surf under cross-onshore winds for most of that time. The combined swell energy is low, mostly between 45 and 150, barely enough to get excited about.

The wind is gonna be the story for a while, with moderate to strong breezes from the SW and WSW, making everything choppy and lumpy. Even as the swell picks up a bit toward the end of August into early September, the wind’s still blowing right across it. The surf quality just isn’t there, it’s mostly messy, cross-onshore junk.

You see a couple of days around August 29th and 30th where the swell gets up to 6ft to 8ft (combined energy 362 to 1133), but the wind is strong and cross-onshore, making it a messy, blown-out mess. Honestly, that’s more of a kite-surfing scenario than a clean paddle situation. The water temp is about average for the time of year.

Now, there’s one small window that looks like the only real chance to get a wave. That’s on Friday morning, September 4th. The wind goes totally glassy, with a clean, glassy surface. Swell is a clean 5ft from the W at 10 seconds, with combined energy of 463. That’s your best bet, but it’s over a week away, so it’s promising but not certain yet. The rest of that day, the wind shifts back onshore.

After that, we slip back into poor conditions with cross-shore winds and smaller, weaker surf. By Sunday, September 6th, you get a bit of offshore wind in the morning, but the swell is tiny at 2ft, with weak energy (92). It’s a clean little wave but nothing to write home about.

There’s a big lump of swell forecast for September 7th (12ft, energy 2310), but again, it’s accompanied by strong cross-onshore wind, making it a messy, dangerous proposition for all but the most experienced, if it’s even ridable at all. For me, the standout is Friday, September 4th morning. Mark that one in the calendar.

This is a river break, so it’s not the most consistent spot, and you can expect crowds sometimes. For a longer stretch like this with mostly poor conditions, it’s not unusual for the area. Keep an eye on the forecasts though, it tends not to stay poor for long.

Stay hopeful, stay wet.
