Laguna (Os Molhes) Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cookin’ at Laguna (Os Molhes).

Right now, we’ve got nothing. Sunday the 23rd is flat and messy – tiny swell, no energy, poor surf. Forget it. The good stuff doesn’t show until Monday the 24th.

Monday morning hits with a solid 8ft SSE groundswell, 15-second period, and the combined energy is massive at 2612. That’s a serious pulse of power – this is a strong to very strong wave energy day. The wind is light offshore from the WSW, keeping the lineup clean. This is for advanced surfers only – 8ft is big, and the long period will make the sets pack a punch. Laguna is a beach/jetty/river setup, so long-period swells can sometimes break a bit straight, but with that offshore wind, it’ll still offer some solid corners. Water temp is around 66°, about normal for this time of year. Monday afternoon holds similar size (8ft) and remains cross-off from the south.

Tuesday the 25th morning is a standout. Swell drops to a more manageable 6ft from the SSE, period 12 seconds, and the wind goes glassy – dead calm from the north. That’s a rare treat. Combined energy is 920, moderate to strong, so there’s plenty of push. The surf will be clean and smooth. This is the best window for decent conditions without the extreme size. Afternoon on Tuesday gets ruined by a strong onshore wind from the NE at 12 mph, so morning is your window.

From Wednesday the 26th through Friday the 28th, it’s blown out. Onshore winds from the north to north-northeast pick up hard, 16 to 25 mph, and the swell stays between 4ft and 8ft but the wind just shreds the surface. Not worth paddling out. Kite surfers might have a field day with that wind and solid swell, but for regular surfing, no thanks.

Saturday the 29th and Sunday the 30th look marginal. Swell drops to 4ft, period short at 9 seconds, energy around 283 to 322. Winds are mixed – Saturday morning is cross-off, Sunday morning goes glassy. Those glassy Sunday morning conditions with 4ft swell could be fun for a grovel session, but it’s not gonna light the world on fire.

Monday the 31st sees a slight improvement: 5ft east swell, 10 seconds, and glassy conditions in the morning. Energy is 424, moderate. Could be a sneaky fun session if you’re keen.

After that, Tuesday September 1st and Wednesday September 2nd have offshore winds but the swell drops fast – 4ft then 2ft. Thursday the 3rd morning looks promising with 6ft SSE swell, 10 seconds, and glassy conditions. Energy hits 583, moderate. That’s a late window worth keeping an eye on.

Beyond that, the second week looks average at best. Swell stays small or gets blown out by onshore winds. No big standouts.

So, to sum it up: Monday morning the 24th is the big-wave day for experts – powerful and clean. Tuesday morning the 25th is the sweet spot for the rest of us: 6ft, glassy, clean. That’s your best bet. If you miss it, wait for Monday the 31st morning or Thursday September 3rd morning for cleaner but smaller waves. Keep the faith – when it comes together at Laguna, it can be magic.

Rusty.
