The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Ogmore-by-Sea.
Look, I’ve got to be honest with you. The next ten days or so are a bit of a write-off for actual surfing. The swell is tiny, the wind is messy, and the whole setup is just not cooperating. We’re looking at a long, dry spell from now until the end of the first week. From the 14th of August all the way through to the 23rd, it’s basically a flat spell with poor to non-existent surf. The energy is weak, with the combined swell energy barely cracking 100 (47) at its best, and most days it’s well under that. The water is warm, though – about 69°F, which is much warmer than normal for this time of year, if you fancy a paddle, but that’s about it.
The only real glimmer, and I mean the only one, shows up right at the end of the forecast window. It’s a long way out, but around Friday the 28th of August, things look like they might finally wake up. A solid groundswell arrives, pushing in from the WSW with a period of 12 seconds and a serious amount of energy behind it – we’re talking combined energy of 3275. The swell is going to be a meaty 12ft, which is well into expert territory. The wind is forecast to be a strong offshore from the ENE, which will clean the waves right up, but at that size, paddling out will be a battle. This is not a beginner’s day. The break is a river mouth, so it’s sheltered, but with that much power, expect it to be heavy and take a real commitment to handle. It’s a long-range call, so keep your fingers crossed, but it’s the only shot we’ve got in the whole 16-day window.
Saturday the 29th still has some decent leftover swell, around 10ft from the WSW, but the wind is shifting to a cross-off from the NNE, so it will still be clean. The energy is strong (1564), but it’s still a big, powerful wave for experienced surfers only.
Other than that, the whole period is a washout. Hang in there, lads. Forecasts can change.
Rusty.
