The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for Ersary beach (Barra). I gotta be straight with you – it's a bit of a rough patch for the next week or so.

The whole forecast period is pretty grim. We’ve got a solid run of poor surf conditions stretching from Friday the 7th right through to the end of the week. That’s a long gap with nothing worth paddling out for. The first glimpse of anything remotely surfable doesn't show up until Saturday the 15th.

The real issue is the wind. For the first week, it’s just relentless. From Friday morning the 7th, we’re looking at strong cross-onshore winds piling into a big, messy 8ft to 10ft swell from the WSW. The combined wave energy is massive – we're talking over 900 on Friday morning, jumping to 2140 on Saturday morning – but it's all junk. That’s not surf; that’s a washing machine. Even as the swell drops a touch, the wind stays onshore, making a mess of everything. This setup looks more interesting for kite surfing than paddle surfing, to be honest.

We do get a bit of a reprieve from the wind around Tuesday the 11th, with clean conditions and cross-offshore breezes, but the swell is practically non-existent. You’re looking at 0.7ft to 1.0ft – barely a ripple. The energy is down in the low double digits (39). It's clean, but there's nothing to ride.

The first real chance to get wet comes on Saturday the 15th. The morning starts clean with a slight air, and the swell fills in a bit to 3ft from the SW. The energy is still low (76), but it’s surfable. The afternoon looks even better, with a gentle offshore breeze from the SE cleaning up that 3ft SW swell. Sunday the 16th also offers some hope with a moderate offshore wind from the east and 3ft swell. It's not going to be pumping, but it’s a clean, rideable wave after a long, dry spell. For a beginner-friendly, consistent spot like Ersary, these are the windows to target.

Later in the week, on Monday the 17th, we get a pulse of 5ft swell from the NW. The wind is light and cross, then clean cross-off. The energy is moderate (241). It’s another ‘ordinary’ day, but not a write-off.

The real standout, if you can wait, is Thursday the 20th. We’ve got a proper 8ft swell from the WSW rolling in. The wave energy is strong (1176). Now, at that size, it’s getting into expert territory, but the wind is light and only cross-onshore, so it might be lumpy. It’s a marginal forecast, but it’s the biggest, most energetic swell on the board. By Friday the 21st, the wind is howling again from the SSE at 25 mph, cleaning it up but making it a battle.

So, to sum it up: the first week is a write-off. The weekend of the 15th and 16th offers the best clean, small waves for a beginner. The big, powerful swell comes on the 20th, but conditions are questionable. Hang in there.

Rusty.
