The Lowdown
Alright, Rusty here. Let's talk about what's brewing for the next couple of weeks.
It's a pretty quiet stretch for Ogmore-by-Sea right now, with a long gap of nothing much happening. The first real chance comes right at the end of the period, so we've got to be patient.
For the first week and a half, from Wednesday the 19th all the way to the start of September, it's flat, small, and messy. There's a bit of energy around the 20th and 21st, with a WSW swell pushing 4ft and a period of 8 seconds, but the wind is on it, making it choppy and unappealing. The combined energy hits 177 for that Thursday morning, which is moderate, but it's all cross-onshore and lumpy. Not worth paddling out for.
We get a few glassy moments on the 21st and 23rd, but the swell is tiny – 2ft or less – so it's just a flat, clean puddle. The water temperature on the 19th is 70°F, which is a massive 8°F warmer than usual for this time of year. That's very unusual, but with no surf, it's a bit of a tease.
There's a slight uptick on the 31st of August. A W swell pushes 5ft to 5ft with a period of 10 seconds, and the combined energy jumps to 489 – that's strong wave energy. But the wind is fresh cross-onshore from the W and NW, making it lumpy and rough. It's a powerful, messy onshore slop. At that size, it's pushing into interesting territory for kite surfers rather than a clean paddle session.
The one standout, and it's a long way off, is on the morning of the 2nd of September. We've got a 4ft WSW swell, but the direction is more W, with a period of 8 seconds. The combined energy is 217 (moderate), and the wind goes glassy from the SSW at 3 mph. That's the only window where the conditions are described as "surfable". It's a river break that's inconsistent and often crowded, and it's sheltered, so it needs a good swell. That morning, it finally looks like it might line up. The swell is a bit short-period, but clean is clean. For a spot that's been dead for weeks, that's the only real chance.
So, save your energy for the 2nd of September. The rest is a write-off.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Ogmore-by-Sea may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
