The Lowdown
Alright folks, Rusty here with a look at what we’ve got on the cards for our local stretch. Let’s get into it.
The good news is there’s no big empty gap at the start, we’ve got something to talk about right away. The real standouts are few and far between, but there’s a couple of moments worth getting the board waxed for.
Our first chance to get wet is Tuesday morning, August 18th over at Mocambique. We’re looking at a clean 5 ft swell from the ENE with a short 8-second period. The wind is a gentle cross-off breeze from the NNW. The combined swell energy is moderate (309). It’s nothing epic, but it’s clean and rideable for an intermediate. Expect the crowds to show up *sometimes*.
Tuesday afternoon holds similar: 5 ft, ENE, still clean with a cross-off. Good for an after-work dip.
Wednesday, August 19th is a write-off. The wind swings onshore from the south and it gets choppy and messy. Not worth paddling out.
We’ve got a couple of smaller, cleaner days on Thursday and Friday (August 20th & 21st) with waves around 3 ft, but the energy drops right off (down to 94 on Friday morning). Surfable if you’re desperate for a slide, but nothing to write home about.
Saturday morning, August 22nd brings a change. A solid 7 ft swell from the south with a 9-second period rolls in. The combined energy jumps to a very strong 1156. However, the wind is a light cross-on from the SSW. It’ll be a bit lumpy and this size is pushing past beginner territory, but it’s worth a look for an intermediate. It gets bigger and choppier in the afternoon.
Sunday, August 23rd stays big (6 ft to 7 ft) from the south-southwest, but the winds are mostly cross-on or onshore, keeping conditions mediocre.
Now, here’s the standout. Monday, August 24th is the one to circle. The morning session looks unreal with a 8 ft swell from the SSE and a long-period groundswell of 13 seconds (1956 combined energy). The wind is dead glassy. That’s as clean as it gets. But I gotta be straight with you: at over 8 ft, this is expert territory. The water’s pushing out some serious power and it’s likely too big for beginners. It’s a clean, powerful groundswell that will be better peeling down at a point or reef than surging straight at the beach.
Tuesday, August 25th is still fun, with the swell dropping to 6 ft from the SSE but still a long 13-second period. Morning winds are a clean cross-off from the north, giving us excellent conditions for experienced surfers.
From Wednesday, August 26th onwards, the swell backs off quite a bit, dropping to around 2 ft to 4 ft through the end of the month. The winds are mostly cross-off, so it will be clean, but the energy is weak (under 500).
Friday, August 28th offers a little spike of hope. A clean 4 ft from the SE with a proper 13-second period and a gentle offshore wind from the NW. The combined energy is moderate (545). The morning will offer some very good, clean conditions on that long-period groundswell.
From Saturday, August 29th through to the start of September, it’s a real mixed bag with mostly onshore winds and quick-period, weak windswell from the east. It's looking mostly poor. The morning of September 2nd has a 5 ft SSE groundswell with a 12-second period (721 energy), but the northeast cross-wind will put a chop on the surface and it’s still a week and a half away, so not a lock.
All in all, that Monday the 24th is your best bet if you’re an experienced surfer after some glassy, powerful groundswell.
Rusty.

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.
