The Lowdown
Alright, Rusty here. Let’s get into it.
The first few days are pretty ordinary, but there’s a real pulse of energy building later on. The standout window is around Tuesday, the 25th of August, through Wednesday, the 26th. That’s where the magic is.
Thursday the 20th and Friday the 21st are pretty flat and messy. Small swell, poor conditions, and not worth paddling out for. The water is sitting at about 67°, which is about average for this time of year.
Now, Saturday the 22nd brings a jump in size, but it’s a bit of a double-edged sword. Swell hits 7 ft from the south, with moderate energy (874), but the wind is cross-onshore and the swell is just too big for Mocambique. The same goes for Sunday the 23rd and Monday the 24th – the swell builds to 8 ft with a very long 15-second period, and energy is pumping (2563), but it’s onshore and too much for this spot.
Tuesday the 25th of August morning is the first real highlight. The swell drops to a clean 6 ft from the SSE, with a long 13-second period, and the wind turns offshore from the NNW. Light air, clean conditions. The energy is strong (1144). This is the one to aim for.
Wednesday the 26th of August is even better. Morning brings glassy conditions, light rain, and a 4 ft swell from the SE with a very long 16-second period. That’s a proper groundswell, and the energy is solid (1228). The afternoon is also excellent with a 6 ft SSE swell, clean cross-off wind, and strong energy (1487). This is expert territory, but the quality is top-notch.
After that, Thursday the 27th and Friday the 28th are still rideable but drop off in quality. Saturday the 29th and Sunday the 30th have some glassy mornings and clean surf in the 5-6 ft range, but the swell direction shifts to ENE and the period drops. Worth a look if you missed the main window.
From Monday the 31st of August into early September, the wind turns onshore and the surf gets choppy and messy. There’s a brief bump in size on Thursday the 3rd of September, but it’s cross-onshore and too big again for Mocambique. The outlook fades out from there.
The absolute best bet is Tuesday the 25th of August and Wednesday the 26th. Clean, offshore to glassy winds, solid groundswell, and plenty of energy. Not one for the beginners – this is for the experienced crew.
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.
