The Lowdown

Hey, Rusty here. Let's break down the surf for Praia das Macas over the next 16 days. Right now it's a quiet spell – from today through Saturday the 12th, there's nothing worth the drive. Winds are strong and cross-onshore, the swell's messy, and the scores are zero. Hang tight.

First real hope comes Sunday the 13th. Morning session: light SSE cross-off wind at 6 mph, a chest-high 5ft NW swell (period 7 sec, combined energy 481). Clean and small – ideal for beginners. The afternoon loses the window with a cross-shore breeze, but the morning is a go.

Then Monday the 14th morning is your standout. Glassy conditions – wind from the NNW at 3 mph, calm – and a 8ft groundswell from the NNW at 8 seconds. Combined energy 701 – that's meaty. The waves will be clean, lined up, and punchy. That 8ft is a bit much for beginners, but for anyone with a few seasons under their belt it's a dream. This is the best slot in the entire outlook.

Later in the week it's mostly poor – cross-onshore winds, lumpy faces, no consistency. The second weekend has a couple of weak glimmers: Sunday the 20th morning gets glassy with a 3ft NW swell (energy 144) – surfable but ordinary. Monday the 21st morning sees a light cross-off breeze clean up a 4ft NW swell (289 energy) – decent if you're keen.

Bottom line: aim for Monday the 14th morning if you can, or Sunday the 13th morning as a backup. Everything else is a wait-and-see.

Rusty signing off.
