Alright, let’s have a look at the picture. Southerndown is proper flat and boring right now – nothing doing at all.
The first week and a half is a total dud. From now until July 12th, it’s all tiny, messy surf with cross-onshore wind. Wave heights are 0.7ft to 3ft, mostly from the west, and the combined energy is weak, sitting between 10 and 127. Not worth paddling out. A couple of clean mornings around the 9th and 10th, but the swell is only 0.7ft – barely a ripple.
Then we finally get something on Monday morning, July 13th. The wind goes glassy, dead calm, and the swell comes in at 2ft from the WSW with a long 12-second period. The combined energy hits 102, which is low-end moderate. It’s small but clean, and for a beginner-friendly break that’s fairly consistent and likes a SW swell, that’s your best bet. Crowds can pop up sometimes, so get there early. Water temp is normal for this time of year.
After that, the wind turns onshore again and it goes lumpy through the rest of the 13th and into the next week. July 16th shows a bit more size – 3ft from the WSW – but the wind is messy and it’s not clean.
So the only real standout in the whole 16 days is that Monday July 13th morning with glassy conditions and a long period groundswell. For beginners or anyone wanting a clean little wave, that’s the call. Otherwise, it’s a quiet spell.
