Mocambique Surf Forecast and Surf Report

Alright, Rusty here, checkin’ in with the local outlook.

Right now, things are looking a bit ugly to start. We’ve got a decent-sized, short-period S/SSW swell rollin’ in, but a strong S/SSE wind is smashing it up, makin’ for lumpy, poor conditions. It’s not worth paddlin’ out. That initial S/SE swell will actually push into about 10ft by Sunday afternoon, with a cross-on wind – total mess. So, we’re basically sittin’ on our hands for the first couple of days.

The real story starts to turn early next week. By Tuesday the 8th the wind finally swings around, with a light offshore (WNW) in the morning. We’ve got a cleaner, lined-up 4ft SSE swell, with a period of 10 seconds, and a combined swell energy of 434 (moderate). The wave quality picks up, and it stays tidy through the afternoon. Wednesday the 9th looks even better – that swell direction shifts ENE, still 5ft with an 8-second period, but the cross-off winds keep it smooth. The combined swell energy sits at 549-567 (moderate). This is a nice, clean window of surfable waves.

That quiet, clean spell continues into Thursday the 10th, with smaller 4ft ENE swell in the mornin’, droppin’ off in the afternoon to a super-long-period 15-second 3ft SSE pulse (combined energy 483). Friday the 11th is an absolute gem – dead calm, glassy conditions, with 3-4ft ENE/E swell. That’s the best the week gets for clean, user-friendly waves.

Saturday the 12th starts small but gets spicy in the afternoon – a 7ft SE swell rolls in with 10-second period and a combined energy of 1007 (strong). However, the wind swings cross-on, and the guidance notes the swell is predicted to be too big for Mocambique itself. This might be one to watch from the sand.

The following week gets real chunky, but rough. From Sunday the 13th through Thursday the 18th, we’re lookin’ at blown-out, onshore conditions with moderate to fresh winds. The swell stays solid (7-8ft SE with strong energy readings of 984-1209) but it’s messy and choppy. The second half of the week sees it drop off and get sloppy.

Then, out of nowhere, Saturday the 19th of September looks like the real standout of the whole 16-day window. The wind goes clean and light offshore in the morning (cross-off), with a solid 6ft SSE groundswell pumpin’ in. The period is a very long 15 seconds, and the combined swell energy is a massive 1416 (strong). This is a proper, powerful groundswell, but that long period means it’s better suited for a point or reef setup than a beach break, where it might just close out. For experienced surfers at the right spot, this is prime. It gets a little more crossed-up in the afternoon.

After that, the last couple of days (20th-21st) fade back into smaller, less exciting surf.

So, for the best bet: Tuesday the 8th through Friday the 11th gives you the cleanest, most manageable waves. But the one to really circle on the calendar is Saturday the 19th of September, with that powerful, long-period groundswell and light winds – it’s the big, promise-filled swell of the run, but keep in mind it’s a long way off and things can shift. Water temp at Mocambique is 67°F, which is spot-on average for this time of year, so the shorty is still the call.

Rusty.
