The Lowdown
Alright, it’s Rusty here. Let’s be straight with you: the next 16 days look pretty grim around Ersary beach (Barra). There’s no good surf on offer at all through the whole period. Every single session is marked as poor surf conditions, so I’m not going to sugarcoat it.
The first few days, from Wednesday the 15th through to the end of the month, are all flat or tiny. The swell is consistently small, mostly around 0.3 ft to 2 ft, with a couple of slightly bigger pulses but nothing that gets the heart racing. The wave energy is weak, mostly two-digit figures like 48 or 73, and even the occasional three-digit number like 145 or 274 doesn’t bring any quality because the wind is almost always cross-onshore or onshore, often fresh or strong. There’s a moment on Wednesday afternoon the 15th where it goes glassy, but the swell is only 2 ft – clean, sure, but you’d be cheating yourself if you called it surf.
The 24th and 25th of July see a bit more size, with swell heights around 5 ft to 5 ft, and combined energy hitting 274 at one point, but the wind is straight from the WSW at 30 km/h or stronger, cross-onshore, lumpy, and messy. That’s more of a kite-surfing setup than a paddle-surfing one. The 27th Monday morning has a spike in energy (392), but the swell is only 4 ft and onshore wind from the WNW ruins it.
There are no standouts. No windows where the stars align. The break is exposed and consistent, but the forecast just doesn’t deliver. For an area like this, a blank run isn’t unusual – it happens. But the good news is, forecasts can change, and it tends not to stay flat for good.
Stay patient, keep an eye on the charts, and I’ll be back when there’s something worth paddling for.
