The Lowdown

Alright folks, Rusty here. Let's get stuck into the outlook for Praia da Baleia.

We've got a run of surf coming through, but it's not all going to be pretty. The first few days are a bit of a mixed bag with the wind working against us, but there are some absolute gems hiding in the second week. The water here is sitting at 71°, which is a touch warmer than normal for this time of year – a nice little bonus.

The action kicks off on Saturday the 8th of August, but honestly, it's a struggle. We've got a 5ft south swell, but the cross-on wind is making a mess of it. The energy is moderate at 639 and the comment says it's marginal. Not the best way to start. Sunday the 9th is much the same story – onshore winds and lumpy conditions. The swell builds a bit into Monday the 10th, hitting 8ft by the afternoon with a solid 13-second period from the south. That's got some serious energy behind it (3471), but again, the onshore wind is just ruining it. For beginners, 5ft is getting big, and at 8ft, this is expert territory only. Honestly, this setup is looking more interesting for the kite crew than paddle surfing.

Now, here’s where it gets good. Wednesday the 12th of August is a standout. We've got a 6ft south swell with a 12-second period, but the magic is the glassy conditions. The wind is dead calm, and the comment says "expect very good surf conditions." The energy is moderate (893-921). This is the window to get out there – clean, lined-up waves for everyone. Thursday morning the 13th holds onto the glass with a 5ft south swell, still very clean.

Things get a bit messy again after that, but keep your eye on Monday the 17th of August. This is the big one. We've got a 8ft swell from the east, a 9-second period, and it's glassy with zero wind. The energy is strong at 1493, and the comment says "excellent surf conditions for experienced surfers." That's a powerful, clean swell. At 8ft, this is for the confident crew only. It's a long way out, so it's a promising call, but one to circle on the calendar.

The surf starts to fade towards the end of the period, with smaller swells and a bit of cross-shore wind sneaking back in. The 22nd and 23rd of August see some small 3ft to 4ft south swells, but by then it's pretty quiet.

So to sum it up, the best on offer is Wednesday the 12th of August for the clean, glassy conditions and fun 6ft south swell. For the experienced surfers chasing a bigger, more powerful wave, Monday the 17th of August is the one to watch.

Stay stoked.

Rusty.
