The Lowdown
Hey, Rusty here. It’s a grim outlook for this stretch of coast over the next 16 days – a real test of patience. The whole period is plagued by poor conditions and barely any size, so don’t get your hopes up.
From the 16th of August right through to the morning of the 21st, it’s a total no-go. We’re seeing tiny swells—0.3 ft to 0.7 ft—with short periods, and the wind is either cross-on or straight onshore. The combined swell energy is weak, barely getting off the ground. The water on the 16th morning is a bizarre 70°, which is a huge 8° warmer than usual for this time of year. It’s an oddity, but it doesn’t mean good waves.
The 20th and 21st see a little bump in size—up to 5 ft on the 20th morning with moderate energy (378)—but it’s all cross-on or onshore winds, creating choppy, lumpy conditions. It looks more like a kite-surfing setup for that day than a surfer’s dream.
Then the bottom drops out. From the 22nd of August through to the morning of the 28th, the swell is basically flat—0.3 ft to 0.7 ft of nothing. It gets clean at times with glassy or offshore winds (the 23rd afternoon is glassy, the 24th morning is fresh offshore), but there’s no energy. Combined swell energy drops into the single digits or low teens (1 to 25). You might as well be looking at a lake.
The only sign of life comes on the 28th of August: Friday morning delivers a 4 ft WSW swell with an 8-second period and combined energy of 234. It’s the only pulse in the whole 16 days, but the wind is onshore from the SW, so it’ll be messy. By the afternoon on the 28th and into the 29th, it’s back to cross-on winds and dirty surf.
Ogmore-by-Sea itself is a sheltered river mouth that rarely breaks with consistency. Even when there’s a little push, the wind ruins the shape. There are no standout days here. Crowds are often a problem, but this forecast will keep the beach empty.
It’s a poor run. Keep the wax on the rack and wait for a better swell.
Rusty.

A general guide to surfing at Ogmore-by-Sea can be found by selecting the local surf guide option on the grey menu. Our Ogmore-by-Sea surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
