Porto Batel Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

The next 16 days for Porto Batel are a real mixed bag. We’ve got a long stretch of junk to start, with onshore winds and messy conditions. But once we get past the worst of it, a clean window appears with proper NW groundswell rolling in. The best of the bunch is clear.

Right off the bat, the first eight days from Saturday the 22nd of August right through to Thursday the 27th are a write-off. Swell sizes are all over the place from 3ft up to 8ft, but the wind is blowing from the SW, SSW, and SSE, mostly onshore or cross-onshore, with some thunderstorms and rain. The water is a bit colder than average for this time of year at 67°F (anomaly of -2°F), and the combined wave energy is weak to moderate with values ranging from 86 to 909. The surf is just poor. Not worth paddling out for.

Finally, a change comes on Friday the 28th. The morning sees a clean 7ft swell from the NW (period 10 seconds) with a light NNW cross-offshore breeze. That’s a solid setup. The combined energy jumps to 983 (moderate), and the wave comment points to “very good surf conditions.” The afternoon gets even better: 8ft from the NW with an 11-second period, cross-off wind, and energy cranking up to 1514 (strong). This is the standout window. Porto Batel is a point break, so that long-period groundswell is going to wrap in nicely with clean, lined-up waves. It’s a bit overhead—best for experienced surfers, as 8ft is in the expert zone. Crowds are possible here, so be ready to share.

Saturday the 29th still has clean cross-off winds, but the swell drops to 6ft (NW, 10 seconds) in the morning and 6ft (NNW, 9 seconds) in the afternoon. Energy is moderate at 684 and 530. It’s still surfable, but the quality dips a bit—marginal conditions, so pick your tides.

Sunday the 30th morning is a smaller, glassy 4ft (NNW, 8 seconds) with light offshore wind. Energy is weak at 202. It’s okay for a fun longboard session, but nothing special. The afternoon turns cross-shore and messy, so don’t hold out hope.

From Monday the 31st onward, the surf goes quiet again. Small swells from the NW and NNW, under 5ft, with periods around 8 seconds or less. Winds are mostly cross-off or glassy, but the energy is weak (120 to 350) and the wave comments say “poor” or “marginal.” There’s a tiny spike on the 6th of September with a 2ft NW swell and a very long 11-second period, but it’s just too small. The last week is a dud.

So, to wrap it up: Friday the 28th of August is your best bet. The morning session is solid, but the afternoon is the real standout with that 8ft NW groundswell and clean cross-off wind. Saturday the 29th is a decent backup. After that, the window closes.

Rusty out.
