The Lowdown

Alright, let’s take a look at what’s on offer for the next couple of weeks.

Honestly, the start of this run is pretty flat and ordinary. We’ve got some small, weak energy pushing in, but nothing that’s going to get you scrambling for your wetsuit just yet. The water temp is sitting around 66° which is pretty much bang on average for the time of year at Atalaia (Molhes) – no surprises there. The combined swell energy is weak early on, only around 92, so don’t get your hopes up for the first few days.

Sunday the 16th is a write-off – only about 5ft of short-period, wind-affected easterly slop (432 combined energy). Cross-shore wind will leave it looking messy. Monday the 17th and Tuesday the 18th stay small, with waves around 4ft to 5ft, but the wind is better on Tuesday morning with a light cross-off breeze that’ll clean things up a bit, though the swell is still short-period (8s) and weak.

The first real standout doesn’t come until Friday the 21st. That morning, we’ve got clean 3ft easterly swell with a light offshore wind (WSW 15 km/h) and the combined energy ticks up to 114. It’s small but clean – a decent window for a longboard or a fun shape. The afternoon holds up too, with 4ft and light offshore winds, so you could sneak a session after work.

Saturday the 22nd starts glassy with a tiny 2ft, but it’s clean – only worth it for a real log. The afternoon fades into junk.

Now, looking further out, things start to get more interesting. On Monday the 24th, the swell kicks up to 5ft from the southeast with a long period (13s), and the combined energy jumps to 648 – that’s solid moderate energy. The wind is cross-shore, so it’ll be a little bumpy, but there’s real push behind it. This is groundswell, and at Atalaia (Molhes) that longer period can work well, giving you some proper shape.

Tuesday the 25th afternoon is a hidden gem. Only 3ft, but it’s clean, cross-off wind, and the period is a very long 14s with 342 combined energy. The water might be rainy, but the waves will be well-formed and glassy – a classic sleeper session.

The real standout, and the one to circle on your calendar, is Monday the 31st. That morning we’re looking at 7ft of south-southeast swell, clean with a light offshore wind from the west-southwest (10 km/h), and the combined energy is cranking at 833. That’s strong wave energy. The period is a bit short at 8s, but with that size and clean conditions, it’ll be pumping. This is for experienced surfers though – over 7ft, the paddle-out gets serious, and the power is real. The afternoon stays offshore but winds pick up to 30 km/h, so get it early.

Overall, there’s a gap of small, average surf from the 16th through the 20th, then a gradual build. The best on offer is clearly Monday the 31st morning, with Tuesday the 25th afternoon as a sneaky good option if you want clean, lined-up waves in a smaller size.

Stay stoked,
Rusty
