The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. I’ve looked over the next couple of weeks for the region, and it’s a bit of a tough stretch for us. The short story is that the surf window is pretty much shut for a while, and we’re looking at a real run of flat, weak, and messy conditions before we see any real push.
The first few days are a total no-go. Through Monday, Tuesday, and Wednesday, we’re looking at tiny, weak swell with onshore winds chopping everything up. There’s just nothing to get excited about. This flat spell is going to last a solid week, honestly. From the 17th through to the 25th, there’s no real surf on offer. It’s going to be a long, dry spell for the board.
Now, as we head into the back half of the month, things start to pick up. On the morning of the 26th, there’s a little bump of energy – a 3ft swell from the WSW with a period of 8 seconds. The wind is offshore from the SE, so it’s going to be clean, but it’s still pretty small. It’s a sign of life, but not much more.
The real change comes at the end of the month. Friday the 28th sees a bit more size, but the wind is all wrong, onshore and choppy. It’s not going to be worth the paddle. The 29th holds a bit more swell, pushing 6ft from the WSW, but it’s still riddled with cross-onshore winds, making it lumpy and tough.
The standout window, however, is looking like that final morning push on the 31st of August and into the 1st of September. We’ve got a solid 7ft of WSW swell, with periods around 7-8 seconds. The energy is starting to really fill in the water, with combined wave energy numbers getting up there – we’re talking between 503 and 645 for the main swells, which is a solid, powerful push. The issue is the wind. It’s all onshore and cross-onshore, and quite fresh. This isn’t going to be a clean, groomed session. It’ll be powerful, a bit wild, and honestly, for a river mouth like Ogmore-by-Sea (Ogmore-by-Sea), this size and wind combo is going to be messy. It’s more of a challenge for experienced surfers in the know, or maybe even more interesting for the kites. For most of us, it’s not going to be the perfect barrel.
The water is running at about 70° right now, which is about 8° warmer than usual for the time of year – that is very unusual and a real bonus. We’ve got that to look forward to, at least.
So, keep your expectations low this week, get your fix of clean air, and keep an eye on that last day of the month for a bit more grunt, even if the wind is against us.
Rusty, out.
