The Lowdown
Alright, Rusty here. Let's be honest with you, the next couple of weeks are looking pretty grim for a proper surf. The whole 16-day window is a write-off, I'm afraid. There's just no swell to speak of that can make anything worthwhile.
We start on Saturday the 15th of August with a tiny 1ft WSW swell, but it's blown out by onshore winds. That sets the tone for the whole period. The swell stays small, mostly under 3ft, and when it does tickle a bit higher, the wind is all wrong – strong onshore and cross-onshore. The wave energy is pitiful, barely scraping into triple figures on the 20th with 121 (combined energy of all swells directed here) and that's the highest it gets, but it's still a messy 4ft of wind swell with a short period of 7 seconds.
The only real glimmer of clean conditions comes late in the run, but the swell is non-existent. By the 21st we get a glassy morning, but on a 2ft, 9-second wave it's barely a ripple. Then from the 22nd through to the 30th, we see some clean offshore winds, particularly from the ENE, and even some glassy conditions. But look at the swell: 0.7ft, 0.3ft... these are lake conditions, not surf. You'd be better off on a paddleboard. For the surfer who just wants to sit on a board and not get wet, maybe. For a wave? Forget it.
The water temperature is a notable one. On the 15th, it's sitting at 70°F with a 8°F anomaly. That's much warmer than usual for this time of year, so if you do go for a float, you won't need a thick suit. But don't kid yourself, there's no surfable wave to be had. It’s a blank run, and it's going to stay that way for the whole 16 days. Forecasts can change, but right now, it's a hard no from me.
Rusty.

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.
