Table - best surf conditions forecast for Ersary beach (Barra) over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s on offer for Ersary beach (Barra) over the next couple of weeks.
To be straight with you, the first week is a tough one. We’ve got a bit of a rough start and a long dry spell in the middle. Thursday the 9th sees some swell, but that wind is a mess. The best of the early action is Thursday morning with a 5 ft swell from the WSW, but a 30 km/h south wind is cross-offshore, making it ugly. The combined energy is moderate (550), but the conditions are just marginal. By Thursday afternoon, we get a bigger 6 ft swell (808 energy), but the wind swings to the southwest at 25 km/h and goes cross, so it’s choppy.
Then it gets quiet. From Friday the 10th all the way through to Monday the 13th, the surf is either too small or the wind is just wrong. We’re looking at a solid four-day gap of nothing worth paddling for. The swell drops right off, with heights under 3 ft and weak energy readings down to 27. It’s a real bummer.
Now, things start to perk up a little on Tuesday the 14th. The morning shows a 3 ft swell from the west (11-second period) with a lovely offshore wind from the east at 15 km/h. The energy is moderate (188) and the conditions are clean. The afternoon is even better – glassy, with a 3 ft west swell and zero wind. It’s small, but for a clean, gentle session, that’s your standout window. The water temperature is about average for the time of year, so no surprises there.
Wednesday the 15th has a clean 2 ft wave in the morning, but it’s tiny. After that, the wind turns nasty again from the 16th onward. The second week looks bleak. From the 16th to the 21st of July, we’re stuck with poor conditions, mostly cross-onshore winds from the north, and small, weak waves. The swell tries to build on the 22nd – a 6 ft wave in the morning and a chunky 8 ft in the afternoon, but the wind is a fresh 35 km/h cross-onshore from the north. The energy jumps to a massive 3797, but it’s all wind chop. This is more of a kite-surfing day than a paddle-surfing one. The period is 13 seconds on that big afternoon set, which is a long groundswell, but with that onshore wind, it’s just a mess at a beach break like this.
Bottom line: if you’re desperate, the cleanest waves are Tuesday the 14th. It’s small, but it’s the only time the stars align. The rest of the run is a write-off.
Rusty.
