The Lowdown
Alright, Rusty here again, but this time in feet and Fahrenheit for you.
Let’s be honest, Ersary beach (Barra) is looking like a ghost town for the next 16 days. There’s absolutely nothing on the cards. Every single session in the forecast comes back as “poor surf conditions,” and there’s not a single recommendation worth a damn. The ocean is asleep.
It kicks off on Thursday, July 30th. We’ve got a 5ft swell from the WNW, but it’s a short-period 7-second windswell with a 30 km/h onshore wind. The combined energy is moderate (214), but it’s a total mess, blown out and ugly. It goes downhill from there. The swell drops, the wind stays onshore or cross-shore, and the wave heights barely get above 3ft. The period is short, mostly 6 to 8 seconds.
There’s a little window around the 4th of August where the wind goes light and even glassy, but the swell is a joke – just 0.7ft to 1.0ft. The combined energy is in the single digits. It’s a pond. You could paddle a board, but you’re not surfing. The rest of the first week and into the second is more of the same. There’s a tiny bump on the 9th of August with a 3ft swell from the NW, but it’s a 4-second period from the WNW, which is just wind-chop. The wind is light cross-on, so it’s not clean, but it’s not a wave.
Into the second week, from the 10th of August onward, the numbers are just as flat. The swell is tiny, the period is short, and the wind is a mix of cross-off and cross-on. The confidence is low because it’s so far out, but the direction is clear: nothing. The 14th of August, the last day, shows 0.7ft and a 7-second period. That’s your lot.
The water temperature is a normal 58°F for the time of year, which is about average. This is a real flat spell for Barra. It’s an exposed beach break, but the energy just isn’t here. The wind is all wrong.
It’s a total blank. The board stays in the shed. The forecast can shift, but right now, there’s nothing to get excited about.
Rusty.
