The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
Honestly, the outlook for Ersary beach (Barra) is a real tough one to swallow. We’re looking at a long, dry spell with no surf on offer at all. The water is sitting at 58°F which is pretty much what you’d expect for the time of year, but that’s about the only thing that’s normal.
Starting Tuesday the 21st, it’s a mess. A NNW wind is blowing cross-on at 16 mph, with a weak, short-period 3ft NW swell. The combined energy is a paltry 124 - weak stuff. That pattern just keeps going. Wednesday the 22nd doesn’t get any better, with a 3ft NW swell and cross-on wind. Thursday and Friday aren’t worth a mention either - the wind is still cross-on, and the swell is small and messy.
Saturday the 25th sees a bit of a jump in size, with a 7ft W swell rolling in. The combined energy is strong at 1198, but it’s got a 10-second period and the wind is onshore. The report says it’s marginal at best, so it’s not one to get excited about. Sunday the 26th through to Wednesday the 30th is more of the same - fresh onshore or cross-on winds and lumpy, poor surf. The size lingers around 5ft to 7ft, but the quality is just not there for a paddle.
Things really drop off at the end of the month. From Thursday the 31st onwards, the swell fades to under 3ft, and while the wind does turn offshore or cross-off at times, the energy is just too weak. By the 2nd of August, we’re talking about 1ft waves with a combined energy of only 17. There’s a moment on Monday the 3rd of August where the wind goes glassy, but the swell is a pathetic 2ft. It’s a flat spell, plain and simple.
There’s just no standout here. The west-facing exposure is getting the right direction, but the wind is never right for clean, surfable waves. This is a blank run for the area. There’s nothing to recommend for a surfer until the forecasts change.
