The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s on offer for Ogmore-by-Sea.
Straight up, the next couple of weeks are looking pretty grim. The whole 16-day window is a bit of a write-off, to be honest. There’s no good surf on the cards at all. The forecast is full of poor surf conditions, with onshore and cross-onshore winds messing things up. The water temperature is sitting at 69°F on the 30th of August, which is a whopping 8°F warmer than usual for this time of year – that’s a really unusual warm spell, but it doesn’t help the waves.
We’ve got a bit of a bump in swell energy from the 31st of August through to the 4th of September, with the combined energy reaching 466 (moderate energy) on the Monday morning, but it’s all coming with a moderate cross-onshore breeze and a choppy, messy surface. The swell direction is mostly WSW, a bit cross-shore for the river mouth, but the wind is just ruining any chance of a clean wave. The swell height gets up to 6 ft, but with that short period of 7-9 seconds and the onshore wind, it’s just lumpy and junky. Not a paddler’s friend.
The 6th of September sees a brief window of glassy conditions on the Sunday afternoon, but the swell is tiny – just 1.0 ft, with a combined energy of 14 (weak). Not enough to push a surfboard, really. The 10th of September brings a nice offshore breeze from the east, but again, the swell is only 2-2 ft, so it’s flat and clean, not surfable.
The 12th of September is the closest we get to anything vaguely surfable, with a glassy morning and 3 ft of swell, but the period is a short 7 seconds and the energy is still weak (81). It’s described as “surfable but very ordinary conditions,” which is the best the whole 16 days can manage. After that, it fades right off again.
The rest of the second week is a mix of small, weak swells and onshore or cross-onshore winds. There’s a long gap of nothing from the 13th of September onward, with barely any energy at all.
Ogmore-by-Sea (United Kingdom) is a river mouth, so it needs a decent swell and light winds to work. With the forecast showing nothing but poor conditions and the swell being small and wind-affected, it’s a no-go. There’s no standout swell, no window of clean, rideable surf. Save the petrol and don’t bother paddling out for the next couple of weeks.
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.
