The Lowdown
Alright folks, Rusty here. Let’s check out what Mother Nature is cooking up for us over the next 16 days. It starts off slow, so don’t rush, but there are some proper moments to aim for.
Friday the 11th is a tough start. We’ve got a 1.1m NW swell (160 combined energy) with a cross-off wind from the NE at 5 km/h. The water’s at 19°, feeling 2° colder than usual – a real fridge for this time of year. Saturday the 12th is flat and glassy with a 0.9m NW swell (95), but nothing to write home about. Sunday the 13th brings a change: a 0.6m NNW swell with a 14-second period (227 moderate energy). That’s real groundswell, and it’s clean with a NE cross-off in the morning. Monday the 14th is similar, with a 1.1m NW swell at 12 seconds (338 moderate energy) and light offshore winds. If you’re keen on small but clean lines, these are your early windows.
Things go flat and choppy from Tuesday the 15th through Wednesday the 16th. Then, bam. Thursday the 17th morning is the first real standout. A glassy 1.8m NW swell (1008 very strong combined energy) rolls in with zero wind. That’s expert territory – steep, clean, and powerful with a 10-second period. This is a session for the strong paddlers.
After a mixed few days, the second week has a major highlight. On Tuesday the 22nd of September, we get a gloopy 1.3m NW swell with a very long 13-second period and 733 strong combined energy. It’s dead calm – glassy conditions. This is premium surf. Long-period swells like this love points and reefs, and at Zambujeira do Mar, it should line up beautifully. You might see a few other surfers there, but with conditions like that, you’ll happily share. Saturday the 19th is also a decent backup with a clean 1.1m NW swell and offshore ESE wind.
So, the game plan: Thursday the 17th morning for the big, clean sets, and Tuesday the 22nd morning for the absolute best of the run. That 22nd session is the one to schedule your day around.
Ride safe.
