The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s heading our way at Mocambique over the next couple of weeks. It’s a bit of a mixed bag, so pay attention.
Right off the bat, we’ve got some swell but it’s going to take a bit of patience to find the good windows. The first few days are looking tricky.
Saturday the 15th kicks off with a 7ft easterly swell, but it’s being pushed around by a 15 mph cross breeze from the ENE. That’s going to mess up the surface. The wave energy is moderate (923), but the wind’s the problem here.
Sunday the 16th is where it gets interesting. The morning sees a 7ft ENE swell with a light north wind – clean, cross-off conditions. That’s a solid, good-looking wave for intermediate surfers. The energy is still decent (638). Definitely the best morning of this early run.
Monday the 17th though, that’s the standout for this first week. The swell drops a touch to 6ft from the ENE, but the wind goes light northerly again, keeping it glassy and clean. The energy jumps up to a healthy 1078, meaning there’s real push behind those waves. This is your call for a proper session. Later in the day, it stays clean but the energy drops.
After that, things go quiet. From Tuesday the 18th through to Friday the 21st, we’re looking at small, weak swell (energy dropping below 200 in some spots) and mostly onshore or cross-shore winds. Not worth paddling out for. There’s a poor run here, so just wait it out.
Now, Saturday the 22nd brings a shift. A southerly swell arrives, building to 7ft by the afternoon, with a 6 mph cross-breeze. The energy is strong (1187). This is a promising return.
Sunday the 23rd is a write-off. Strong southerly winds will make it a mess.
Monday the 24th is a big one, but for experts only. A 8ft southeast swell with a very long period of 15 seconds. That’s a serious groundswell. The energy is massive (2167). The wind is a light cross-on from the south, so it’ll be lumpy but powerful. Only for the experienced crew. The same goes for the afternoon, with a 7ft swell and 14-second period.
Tuesday the 25th sees the size back down to a more manageable 5ft, still with a long period (14 seconds), but light cross-on winds. The energy is still very high (1020+). This is a solid day for intermediates if you can handle the longer gaps between sets.
The real gem looks to be Wednesday the 26th. Morning brings a 5ft SSE groundswell with glassy conditions – zero wind. Pure, clean lines. The energy is strong (655). Afternoon gets a bit bigger at 8ft, but the period drops to 7 seconds, so it’ll be a different beast.
Thursday the 27th offers another clean session with a 4ft SSE swell and cross-off winds. Clean and fun.
Friday the 28th morning is glassy with a 6ft easterly swell – another great chance for clean waves, though the energy is moderate (536).
Saturday the 29th is a write-off again with onshore winds. Skip it.
Sunday the 30th rounds out the outlook nicely. A 4ft southerly groundswell (12-second period) with glassy morning conditions. Clean, calm, and a lovely way to finish.
So, to sum it up: the real standouts are Monday the 17th for a clean, punchy session, and Wednesday the 26th morning for the glassy, long-period groundswell. Keep an eye on Tuesday the 25th for powerful but manageable waves.
The water temp is sitting at 65°, which is pretty average for this time of year – nothing unusual there.
Remember, this is Mocambique we’re talking about – fairly consistent, but you’ve gotta pick your windows. Today and tomorrow, bide your time.
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.
