The Lowdown
Alright folks, Rusty here. Let's be straight with you – it's looking pretty bleak on the surf front for a good while. We’ve got a long stretch of flat, weak, and messy conditions ahead, so those boards might be collecting dust for a bit.
We're looking at over a week of poor surf, to be honest. The waves are tiny and the wind is all over the place. We'll see some small bumps, but it's not going to be anything worth your time. The first real bit of swell doesn't show up until Tuesday, September 1st, so be prepared for a long wait.
Here’s the rundown. The water is a very unusual 69°F, which is way warmer than normal for this time of year at Ogmore-by-Sea.
Now, let's talk about that first bit of energy. Tuesday, September 1st sees a push of swell, bumping up to 7ft from the WSW. The energy readings are strong, so there's some juice behind it. But, and it's a big but, the wind is howling from the NW at 22 mph. That's a strong cross-shore breeze, which will chop it all up and make it a mess. While there's size, it won't be clean and is definitely for experienced surfers only, as it's pushing over 8ft at times.
The following day, Wednesday the 2nd, the swell backs down a bit to 5ft but the wind swings onshore from the WSW at 12 mph. It’s still not great. The whole setup over this period is just too messy, with onshore and cross-onshore winds.
If you’re desperate, early on the 1st at the river mouth might be your best bet for the biggest, most powerful waves, but the wind will likely make it a battle. Honestly, with this much cross-shore wind and messy conditions, it looks like it might be a better time to be a kite surfer than a paddle surfer.
So, mark your calendars for the 1st of September, but keep your expectations low. It's a long-range call, so things could change, but right now, it's not looking like a day to write home about. The forecast could change, so keep your eyes peeled for updates. We'll get some good surf again eventually.
Rusty.
