The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
To be honest, it’s a pretty grim start. We’re looking at a long, dry spell with no surf worth paddling out for. From now until the 24th of July, you’re better off leaving the board in the car. The wind is messy, mostly cross or cross-onshore, and the little bumps of energy that do show up are just too weak to do anything with. There’s a real stretch of flat days in the middle there, particularly from the 19th to the 22nd. It’s a proper blank run.
The first real glimmer of hope comes on the morning of Saturday the 25th. Barra da Lagoa is looking at a solid 5ft swell from the SSE with a period of 10 seconds, and the wind is swinging light cross-off. It’s still a bit tricky by the afternoon, but the overall energy is starting to build (437). That’s a solid, clean day for the beginner-friendly waves here.
The standout, without a doubt, is the Saturday afternoon of the 25th. The swell dips a touch to 5ft, but the period stretches out to a nice 12 seconds from the SSE, and it goes glassy. The energy jumps to 667, and it’s going to be very good surf conditions. The water temp is about average for this time of year, so no surprises there. If you’re an intermediate or above, that’s the session to circle.
Looking further ahead, the 1st of August (Saturday morning) shows a big 8ft SSE swell (period 13 seconds) with light cross-off wind and clean conditions. The energy is very strong (1993). That’s a powerful groundswell, and for a beach break like Barra, it might be a bit heavy and straight. This one is definitely for experienced surfers only. It’s a promising forecast, but it’s a long way out, so keep an eye on it.
So, overall, the first week is a write-off. The second week has a couple of gems, with the 25th afternoon being the best bet for clean, fun waves.
Rusty.
