The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for Ogmore-by-Sea over the next couple of weeks. I’ve got to be honest – it’s a rough one. There’s a long dry spell right at the start with nothing worth paddling out for, so don’t bother grabbing your board just yet.
We’ve got a blank run from now all the way through to the early hours of Tuesday, September 22nd. That’s a solid couple of weeks of onshore junk, messy wind, and small, weak waves that just won’t clean up. The wind is mostly cross-on or straight onshore, which is a killer for this sheltered river mouth. The combined swell energy stays low to moderate throughout that period, often below 100 (like 26 mm to 97 mm) and only occasionally climbing into the low hundreds, but it’s always paired with poor conditions.
The only real glimmer of hope, and I mean the only one, comes on Tuesday morning, September 22nd. That morning we finally see a shift. The wind swings around to a cross-offshore from the NNE, blowing at a light 9 mph. That’s a game-changer for the wave faces. There’s a 5ft swell coming from the WSW with a short period of 7 seconds – not a groundswell, just a weak windswell, but with that clean wind, it’ll be rideable. The combined swell energy is moderate at 228, and for once the report says “surfable waves but very ordinary conditions.” For this stretch, that’s a standout. The break is Ogmore-by-Sea itself – a river mouth setup that’s inconsistent and sheltered, so this is a rare window. The water temp is about average for this time of year, nothing weird.
Honestly, mate, that Tuesday morning is your only shot. It’s not big, it’s not perfect, but it’s clean. After that, the forecast gets messy again with onshores and lumpy seas. Keep an eye on it, but don’t hold your breath.
Rusty.
