The Lowdown
Alright folks, Rusty here, let's have a look at what's on the cards for The Rock-Costa Azul.
Right off the bat, we're looking at a bit of a slow start. The first real window of opportunity isn't until Tuesday afternoon, so you've got a little time to get the gear sorted. The water is sitting at a balmy 89°, which is a massive 7° warmer than usual for this time of year – that's some seriously unusual tropical feels, you won't be needing a wetsuit.
The pick of the whole period, the one you want to circle on the calendar, is Saturday afternoon, the 29th of August. The Rock-Costa Azul is a reef break, and it's exposed to the south swell. We've got a solid SSW swell pushing in at 4ft with a period of 15 seconds, that's a proper groundswell with some punch. The wind is a light cross-offshore from the west, which is going to groom those waves into nice, clean lines. The combined energy is sitting at 1000, showing there's plenty of power in the water. It's a wave for experienced surfers, but if you've got the skills, this is the session. Just be aware, this spot can get crowded, so get in early.
Sunday morning, the 30th of August, is another standout. The swell drops slightly to 4ft from the SSW, but the wind swings to a glassy easterly. That's as good as it gets for clean conditions. The energy is a little lower at 710, but the total lack of wind will make for some silky smooth walls.
Friday afternoon, the 4th of September, is a promising one for the long-range forecast. The swell builds to 5ft from the SSW with a period of 16 seconds, packing a strong energy of 1283. The wind is forecast to be calm and glassy on Friday morning, so that's your window to get out there before the afternoon cross-onshore kicks in. It's a bit far out, so keep an eye on it, but it has the potential to be the best of the second week.
For the rest of the outlook, we've got a mix of clean windows and funky conditions. The swell is a bit on the weaker side for a lot of the mornings, and the wind is often a bit cross or onshore. The period often hangs around the 14 to 18 second mark, which is a long period groundswell. At The Rock, a reef break, that long period energy should wrap in nicely, but just be aware the sets will be a bit more spaced out, making it easier to get a position.
All in all, Saturday the 29th is the one to aim for, with Sunday the 30th a close second. Conditions are cooking up for a good run.
Rusty.
