Mocambique Surf Forecast and Surf Report

Alright, Rusty here. I've got the lowdown for the Mocambique zone. This forecast runs from August 18th all the way to September 2nd, but you’re going to have to sit through a quiet, messy period before the gold shows up.

For the first week or so, it’s pretty lackluster. We’re dealing with small, short-period windswell from the ENE, mostly around 3ft to 3ft, with periods barely hitting 8 seconds. The wind is mostly cross-off or light, so the surface might look okay, but there's just no juice. The combined swell energy is weak, mostly between 94 and 200 for those days. Honestly, don't bother; you'll be wasting energy.

The action kicks in on Tuesday, August 22nd. The swell swings to the south, and early Saturday morning we get a solid 7ft south swell with a 9-second period. The combined energy jumps to 1084. That's moderate. But the real kicker is the wind: glassy. Slight air, completely flat water. The water temp is about 65°F, which is normal for the season. This is a serious window for the more experienced crew; the set waves will have some heft, and the surface will be like a mirror. The break is fairly consistent and exposed to the south.

If that 7ft glass is a touch too spicy, Sunday morning the 23rd is a treat. A 5ft south swell, but with a period stretching to 11 seconds – that’s a proper groundswell. Glassy again with a slight air, and the energy is still strong at 547. This is cleaner, with longer waits between the bomb sets, but when they roll through, they'll have shape and power. That's the session you want.

Monday the 24th brings a big jump. We're looking at 8ft south swell with a 13-second period. The combined energy hits 2192 – strong. But for this spot, that's too much size. The wave comment says it’s a size issue, so unless you're a local charger on a step-up, give it a miss. The wind is also onshore, making it a messy, washed-out mess.

The absolute standout of the whole 16 days is Tuesday morning, August 25th. The swell drops back to a punchy 6ft from the SSE, period still a meaty 13 seconds, and combined energy at 1174. And we get glassy conditions again with a slight air from the NNW. This is the gem. It’s marked as excellent for experienced surfers. The combination of a strong, long-period groundswell, the right direction (SSE), and flat-calm winds is a rare find. This session will be clean, powerful, and consistent.

After that, we get a string of clean days through the 27th and 28th with swells between 4ft and 5ft from the south and east, periods up to 17 seconds. The wind stays cross-off or offshore, keeping the faces smooth. The 26th morning has a tiny 4ft SE swell but with a *17-second* period – that's ultra-long period groundswell. It'll be glassy clean, but the wave height is small and with that period, it might be breaking too straight for the beach. Still, for a longboard it could be very special. The energy is still moderate.

The first of September brings another spike – 8ft SSE swell, but with a moderate onshore wind. That’s a big, messy wave. Then the 2nd has a 8ft SE swell with the wind onshore. Too much size and dirty wind.

So, to wrap it up: Sunday the 23rd for the cleanest, most user-friendly groundswell, and absolutely do not miss Tuesday the 25th. That’s your best chance for a standout session. The crowds at Mocambique are marked as "sometimes", so expect a few heads in the water.

Keep it salty.
