Alright crew, Rusty here. Let’s cut to it – we’ve got a long dry spell ahead before anything is worth getting wet for.
Right now, there’s no surf on offer. We’re looking at a big gap with nothing recommended from now. The first chance for a wave doesn’t come until Sunday morning, July 12th, and it’s barely enough to call surfable.
Overall Pattern: For the next week and a half, the wind and swell are just wrong. Most days are blown out with choppy, cross-onshore wind and weak, short-period windswell. The combined wave energy sits low, mostly under 100 (weak), with a brief kick up to moderate (158) on that Sunday. You’ll see some moderate energy mid-week (around 288-352), but strong winds ruin any chance of decent surf.
The only real standout in the whole 16-day outlook is Sunday morning, July 12th.
The Best on Offer:
Get to Praia das Macas. Sunday morning is your only real shot. We’ve got a small, clean 3ft swell from the WNW. The wind is glassy – dead calm out of the west at 4 mph. That’s gonna leave the surface smooth as butter. The period is 9 seconds, so it’s a little short, but it’ll have enough juice for the inside. The combined energy is 158, which is moderate. This break is beginner-friendly, so the small size is a bonus for learning or just getting a few easy ones. Water temp is 67°, which is totally normal for this time of year.
After that morning, the wind switches onshore and it’s right back to poor surf for the rest of the 16 days. Late in the run, around Monday July 21st, the swell builds to 5ft to 6ft but the wind is a brutal 25-26 mph cross-onshore. That setup is a messy lumpy mess, and honestly looks more interesting for kite surfing than paddling.
So, circle that Sunday on the calendar. It’s a small window, but it’s the only one.
Rusty.
