The Lowdown
Alright folks, Rusty here with a look at what's on the menu for Praia da Baleia over the next couple of weeks. We've got a bit of a slow start, but there's some quality on the horizon if you're patient.
Overall, the pattern starts off pretty average, with a lot of small, short-period windswell. We've got a few days of barely rideable waves, but nothing worth paddling out for until the weekend. The real standout action is split across two distinct windows: the upcoming weekend, and then a promising window over a week away.
The water's sitting at a balmy 72°, which is a touch warmer than normal for this time of year – a nice little bonus.
Alright, let's get into it. The first real opportunity kicks off on Friday morning, the 18th of September. Early that day, Praia da Baleia (beach and point) should be glassy with offshore E wind around 3 mph. The swell is a clean-looking 4 ft from the S with a solid 12-second period. Wave energy is moderate (589). It's not huge, but with those conditions, it'll be a really fun, clean session. The crowds can be a bit of a thing here sometimes, so get in early.
Later that day and into Saturday the 19th, the swell gets a bit chunky. Saturday morning sees a jump to 6 ft from the E, but the period drops to a short 8 seconds. While it's glassy with NE wind at 3 mph, that short period will make it a bit lumpy and fat at the beach break. The combined energy is moderate (433). This might be a better option for a bigger board. By Saturday afternoon the swell is up to 6 ft (531), but with that short period, it'll be a bit of a bumpy mess for paddle surfing – might be more interesting for a kite session.
Sunday the 20th is a solid day all round. Morning glassy conditions with NNW wind at 3 mph, and the swell holds at 5 ft from the ESE with a short 8-second period. The wave energy is moderate (358). Not the cleanest lines, but it'll be fun and plenty of waves. The afternoon glass-off looks even better with the same 5 ft of ESE swell.
Then we hit a bit of a lull from Monday the 21st through to Wednesday the 23rd. Waves drop off significantly – we're talking 2 ft to 4 ft with very ordinary energy. It's pretty flat, so don't bother.
Now, here's where it gets interesting. The next real standout window kicks off on Thursday, the 24th of September. Thursday morning is looking prime. Glassy conditions with SSW wind at 3 mph, and a solid 6 ft of SSW swell rolling in with a 10-second period. The combined energy jumps to a strong 622. This is a proper groundswell event. The direction is a great match for the break, and with that offshore wind, Praia da Baleia should be absolutely cooking – clean, lined up, and fun for everyone. Thursday afternoon holds the same quality with 5 ft of S swell.
Friday the 25th is also worth a paddle, with clean 4 ft S swell (11 secs) and glassy conditions. The energy is moderate (382). It’ll be a step down from Thursday, but still a very solid session.
From Saturday the 26th onwards, it fades away again into tiny, weak surf, so that Thursday and Friday window is your best bet for the whole outlook.
This is Rusty, signing off.
