The Lowdown

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.

Information about the Mocambique Surf forecast

The above surf forecast table for Mocambique provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mocambique can be found by selecting the local surf guide option on the grey menu. Our Mocambique surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Mocambique) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Mocambique may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Mocambique is 12 km (7 miles) from Florianopolis. If you plan a holiday in Florianópolis, look for hotels and other accommodation in Florianopolis. Florianopolis has rooms for a wide range of budgets as well as car hire and transport links.
