Table - best surf conditions forecast for Ersary beach (Barra) over the next 16 days.
Alright, folks, Rusty here. Let's get into what the next couple of weeks are looking like for your local spot.
Alright, it’s a bit of a tough one to start. The next week or so is looking pretty grim for Ersary beach (Barra). We’ve got a run of mostly poor surf conditions stretching from the start of the week all the way through to the 14th of July. The combined swell energy is weak to moderate at best, with the highest reading only hitting 886 on the 9th, and even that comes with a lumpy, cross-shore wind and poor conditions. That's not a run you want to paddle out into.
Things finally show a little life around the 14th of July. Tuesday the 14th of July offers a glimmer of hope with some surfable but very ordinary conditions. The swell is small, around 3 ft from the west with a period of about 11 seconds, and the wind is light and clean – a cross-off from the SSE in the afternoon. The combined energy is still only moderate at 141. It’s not a standout, but it’s the most surfable the spot looks in this entire period. It’s the only window where the stars align even a little bit, so if you’re desperate, that’s your moment.
After that, it’s back into a messy, wind-affected pattern all the way through to the 22nd of July, with onshore winds and tiny, short-period swell. The wind swings around a lot, but it's consistently not good. A lot of the wind is cross-on or direct onshore, and it’s often strong, making for choppy, lumpy, or messy conditions.
There’s no real standout day here. The 14th of July is the only one worth mentioning, but even that is a far cry from a classic session. For an exposed spot like this, the long-range outlook is a bust.
Keep the head up, though – the forecasts can always change.
Rusty.
