The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for the Mocambique stretch.
Alright, we’ve got a solid run of surf coming through over the next week or so, but it’s not all plain sailing. The water temp is sitting at 65.5°F, which is bang on average for this time of year, so no nasty surprises there. The best of the action is going to be around the middle of the week, specifically Thursday the 14th of August and Friday the 15th. That’s where the real quality sits.
The pattern starts on Tuesday the 11th of August. It’s a bit of a mixed bag. Tuesday morning has a 6.6ft S swell with a 12-second period, but the wind is a cross-shore 6 mph from the SSW, creating a bit of chop. It’s surfable, but not a standout. The combined energy is strong (1207), but the conditions are marginal. However, Tuesday afternoon goes glassy. The wind drops to zero, and the swell is a clean 5.9ft from the S at 12 seconds. That’s a beautiful window, but it’s a short one.
Wednesday the 12th sees a bit more consistency. The swell drops slightly to 6.2ft from the SSE, with a 12-second period and a light cross-offshore N wind at 6 mph in the morning. The energy is still high (998). The afternoon sees the wind pick up to 9 mph, which is still cross-off, but it’s not quite as clean.
Now, Thursday the 13th carries a bigger, longer period swell. It’s 5.9ft from the SSE, but the period stretches to 14 seconds. That’s a long-period groundswell, which means better shaped waves and more energy, but it might get a bit straight at the beach break. The morning has a cross-shore SSW wind at 6 mph, creating some ripples. The afternoon gets a cross-on wind from the S, so it’s a bit of a write-off.
Here’s the standout: Friday the 14th of August. This is the pick of the forecast. The morning is glassy, with a 5.9ft SSE swell, 13-second period, and a light WSW wind at 3 mph. The combined energy is very strong (1066). The afternoon is also glassy, with a 5.2ft swell and the same period. This is perfect for an intermediate surfer. The waves will be clean, powerful, and lined up. A real treat.
Saturday the 15th is still good, but you’re on the backside of the swell. Morning sees a 3.9ft SSE swell, 12-second period, with a light offshore NNW wind at 6 mph. The energy is moderate (638). It’s clean, but smaller. The afternoon gets windier (12 mph NNW), so the morning session is the one.
Sunday the 16th sees a change. The swell switches to a shorter-period E swell at 4.3ft to 4.9ft, with an 8-second period. The morning is a bit lumpy, but the afternoon is glassy with a 4.9ft E swell. The energy is weak to moderate (321-347). It’s small and clean, better for a longboard or a funboard.
From Monday the 17th, the quality drops. The wind gets messy, and the swell is mostly short-period and onshore. Tuesday the 18th is a no-go with strong cross-on winds. The rest of the second week, from the 19th to the 26th, is a write-off. There’s a big spike in energy (1519) on the 26th of August, but it’s accompanied by strong onshore winds and rain. That’s a kite-surfing setup, not a paddle-surfing one. The swell is too big and the wind is wrong. The consistency is poor from the 18th onwards, so don’t hold your breath for the tail end of the forecast.
So, to wrap it up: Thursday 14th and Friday 15th of August are your days. Get out there for the glassy morning sessions. The rest of the window is either marginal or poor.

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.
