The Lowdown
Right then, let's have a look at what's on the table for the next couple of weeks. I'm looking at Ogmore-by-Sea here, and I've got to be straight with you – it's a pretty quiet stretch ahead. The water's sitting at 69°F, which is much warmer than what we'd normally expect for this time of year, so that's a nice bonus if you're having a paddle, but the waves themselves are a different story.
For the first part of the week, from Tuesday the 11th through to the end of that week, it's really flat. We're talking tiny swells, barely 0.3ft to 3ft, and the wind is all over the place – cross-off, cross, and onshore – so it's just not doing anything for us. The combined energy is weak, sitting between 5 and 143, so there's no grunt in the water at all. Thursday morning the 13th sees a bit of a bump with a 2ft swell from the WSW and a light offshore wind, but it's still poor. Honestly, there's nothing to get excited about.
Then we hit a bit of a gap. From Friday the 14th through to Tuesday the 19th, it's pretty much the same story – small, weak, messy stuff. The wind is mostly cross-on, and the swell heights are hovering around 2ft to 3ft, with energy staying low to moderate. Nothing worth paddling out for.
The first real standout pops up on Thursday the 20th of August. The morning brings a 6ft swell from the west, with a period of 8 seconds, and an ESE wind at 10 km/h that's cross-off, so it's clean. The combined energy is moderate at 364 – that's the most we've seen all week. The afternoon is similar, with a 6ft swell from the WNW and a light SE breeze, still clean. It's surfable, but it's still pretty ordinary. The swell is a bit short in period, so it'll be a bit fat and weak, but it's the best we've got. Ogmore-by-Sea is a river mouth, so it can handle a bit of swell, but it's inconsistent and can get crowded often, so keep that in mind.
After that, Friday the 21st drops back down to 3ft, and the rest of the week into the 26th is a mix of small, onshore, and messy conditions. There's a bit of a bump on Sunday the 23rd with a 5ft swell from the west and a clean cross-off wind, but the period is short at 7 seconds, so it's not going to be special. The energy is moderate at 250, but again, it's just not great.
So, to be honest, there's no real standout session here. The best bet is Thursday the 20th, with that 6ft swell and clean conditions, but it's more of a "if you're desperate" kind of day. The rest of the fortnight is a write-off. Ogmore-by-Sea is known for being inconsistent, so a blank run like this isn't unusual. Forecasts can change, but for now, I'd be looking at other options.
