Table - best surf conditions forecast for Gerpuk Bay - Inside Gerpuk over the next 16 days.
Rusty here, lookin' at the next 16 days for Gerpuk Bay - Inside Gerpuk. Honestly, it’s a tough one. This spot usually pumps – it’s very consistent, a beginner-friendly reef that loves a solid SSW swell. But the wind just ain’t playin’ ball. We’ve got persistent onshore ESE to SE breezes, mostly moderate to fresh, that are trashing the surface. The swell energy is there – we’re seeing moderate to strong readings – with long period groundswell up to 18 seconds. But with the wind howling on it, the wave comment keeps callin’ it “poor surf conditions.” There’s no standout session anywhere in the window. A couple of mornings – like Saturday July 11 and Tuesday July 14 – get a marginal nod with 6ft to 6ft SSW swell, but even then the wind is onshore and the energy is high, so the surface is messy. Later on, Friday July 24 morning shows a marginal 5ft SW swell with a gentle onshore breeze – still not clean enough to get excited about. The rest is locked in poor or marginal at best. For a spot this consistent, it’s frustrating. But forecasts can change, and it doesn’t usually stay this rough for long. Hang tight.
