The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening at Mawgan Porth for the next couple of weeks.
To be straight with you, this stretch is looking pretty grim. We’ve got a long gap of poor conditions before anything even slightly worth mentioning shows up. From Sunday the 23rd of August right through to the end of the month, it’s mostly tiny, weak, or blown-out slop. The energy is pitiful – we’re looking at numbers like 43 to 92 (weak energy) most days, and when it does bump up a bit, the wind ruins it. The water temp is about average for this time of year, nothing special there.
The first real glimmer comes on Monday the 31st of August. The morning is still ordinary with a 3ft swell from the WSW at 8 seconds and a cross-offshore breeze, but it’s the afternoon that’s a little standout. The wind goes glassy, dead calm, and we’ve got 3ft of W swell at 8 seconds rolling in. The energy is still mild at 139 (weak energy), but with zero wind, it’ll be clean as a whistle. It’s not a big day, but for a river break that’s fairly consistent, this is your moment. Crowds are sometimes an issue here, so keep that in mind.
After that, we slide back into poor conditions. A bit of a pulse on Thursday the 3rd of September brings 5ft from the west, but it’s cross-shore and messy. Friday the 4th is similar with 5ft at 9 seconds, but again, onshore flow ruins it.
Then into the second week, things get weird. On Sunday the 6th of September, there’s a big jump in energy – 1027 (strong wave energy) – with 8ft from the west at 9 seconds, but it’s cross-shore and the setup looks more interesting for kite surfing than paddle surfing. The period is short, so it’ll be lumpy and hard to handle. The following Monday the 7th of September has 5ft from the WNW at 8 seconds, but with a near gale blowing 31 mph cross-onshore, it’s blown out completely.
Bottom line: if you’re desperate, hit that glassy Monday the 31st of August. Otherwise, save your energy. This is a tough run for the area.
Rusty.
