The Lowdown

Right then, let's have a look at what the next couple of weeks are shaping up like for Ersary beach (Barra). It’s a consistent, exposed beginner-friendly spot, so it’s a good one to keep an eye on.

The water temp is sitting at 57°, which is pretty much bang on average for this time of year, so nothing unusual there.

Honestly, the start of this forecast period is a bit of a write-off. From Sunday the 13th right through to Tuesday the 15th, we’ve got strong winds and messy conditions. The swell is there, but it's poor surf quality with strong cross-shore winds making a right mess of things. You'd be better off waiting.

Things finally turn around on the morning of Wednesday the 16th. This is the standout of the whole outlook. We get a solid 7ft swell from the WSW with a decent 11-second period, and the wind drops to nearly nothing – a glassy 3 mph from the NNW. That’s going to be clean, lined-up surf. The combined energy is strong at 956. This is the one to get on, for sure.

After that, it gets a bit wild again. From Wednesday afternoon the 16th right through to the end of the week, the wind picks up and the swell gets big – we’re talking 10ft to 16ft from the 17th to the 20th, with very strong energy readings (up to 8144). This is expert-only territory, and with the strong onshore winds, it’s going to be messy. For a beach break, this setup looks more interesting for kite surfing than paddle surfing, to be honest.

We get a brief window on the 21st with some cleaner conditions and an 8ft W swell, but the wind is still fresh. Then it's back to lumpy onshore stuff for the 22nd and 23rd. The 23rd afternoon sees a huge 12ft swell, but the forecast says it’s too big for this break.

The next real bright spot comes on the morning of the 24th. We’ve got a clean 6ft swell from the WNW, and more importantly, a 9 mph offshore wind from the ESE. That is clean, peeling surf. The energy is moderate at 650. It’s a solid option.

The 25th is small, but the 26th looks promising again. The Saturday morning has a clean 4ft WSW swell with a good 12-second period, and the afternoon gets even better with 5ft and lighter winds. Both are clean and worth a paddle.

After that, the last few days of the month drop off quickly in size and quality, so the 24th and 26th are your best bets in the second week, though the 24th is the real gem.

Signing off, Rusty.
