The Lowdown

Alright folks, Rusty here. Let’s get into what’s cookin’ for Praia da Baleia over the next couple of weeks.

We’ve got a solid window of surf kicking off mid-week, but you’ll need to be an experienced surfer to handle the size. The water is a touch warmer than normal for this time of year, sitting at 71°, which is a nice little bonus.

Wednesday afternoon, the 26th of August, is where it’s at. We’re looking at a solid 7ft swell from the SSE, with a very long period of 15 seconds pushing through. The energy is pumping hard at 2067, so this is proper groundswell. The wind is glassy, absolutely dead calm from the SE at just 3 mph. This is the standout session. The wave quality is excellent, but at that size and with that long period, a beach break like this can get a bit tricky – it might be breaking a little too straight. Still, for the experienced crew, this is a cracker.

Thursday morning, the 27th, is another good one. The swell drops slightly to 6ft, still from the SSE, with a 14-second period. The energy is still strong at 1574, and the wind is glassy again from the ENE. This is another clean, powerful session for the experienced. The afternoon gets a bit of a cross-on wind, dropping the quality.

Friday the 28th morning sees the swell drop to 3ft, but with glassy NNE wind and a 12-second period, it’s still clean and fun. The energy is moderate at 636. The afternoon goes a bit flat and messy.

We then hit a bit of a lull. From Friday afternoon right through to Monday the 31st, it’s nothing to write home about – small, weak, and mostly ordinary. Monday morning is glassy but tiny, with only 2ft waves and weak energy of 52. That’s a couple of days of quiet water.

Things start to pick up again on Tuesday, the 1st of September. The swell comes back to about 4ft from the S, with a short 6-second period, but the wind is glassy on Tuesday afternoon. The energy is light at 291, but it’s clean and surfable.

The next real highlight comes on Friday the 4th of September. The morning has a 4ft swell from the S, with a 10-second period and glassy ENE wind. The energy is moderate at 305. It’s not the biggest, but the conditions are clean and the wave quality is good. The afternoon holds clean too.

Saturday the 5th morning is also worth a look. The swell nudges up to 4ft from the E, with a short 7-second period, but the glassy SE wind keeps it clean. The energy is moderate at 319.

After that, Sunday the 6th sees the swell jump to 5ft, but the wind goes cross-on, bringing in some rain and making it more marginal. The following week looks like a mix of small, clean days and some bigger, wind-affected ones. The standout long-range call is for the 8th of September: on Tuesday morning and afternoon, we get a 3ft to 3ft swell from the S with a long 12-second period and glassy SSW wind. The energy is moderate (205 and 346), and the wave quality is good. It’s a promising one for the second week, but you know how those long-range promises go.

The bottom line: get out there Wednesday afternoon, the 26th, for the biggest, cleanest, and most powerful swell of the forecast. Thursday morning is a close second. After that, pick your windows for the smaller, glassy days.

Rusty, signing off.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Praia da Baleia may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
