The Lowdown
Alright, Rusty here, let’s get into it.
So, we’re looking at a pretty mixed bag ahead for Mocambique. The first real standout is Thursday the 27th of August, and that’s the one to circle. Thursday morning, the swell is solid at 6ft from the SSE with a nice long period of 14 seconds – that’s proper groundswell energy, and the combined energy is strong (1222). The wind is a light cross-off from the north, so the face will be clean. That’s the pick of the whole run, no question. It’s a bit much for beginners, but for experienced surfers it’s the best session in the whole 16-day window.
After that morning, things drop off quick. Thursday afternoon sees a score drop, wind picks up, and the swell loses a bit of energy. Then Friday the 28th and Saturday the 29th are pretty ordinary – the swell shifts to the ENE with short 8-second period, combined energy drops to around 460, and the wind is mostly cross or onshore. Not worth paddling out.
Sunday the 30th is a write-off with poor conditions and small weak swell. Then Monday the 31st looks interesting – glassy conditions in the morning and afternoon with light rain, swell around 5ft from the ENE, period 9 seconds. Combined energy is moderate (468). The glassy wind is a big plus, but it’s not a huge swell, so it’s a fun but not epic session.
Tuesday the 1st of September turns ugly – strong cross-onshore wind, and the afternoon swell jumps to 8ft from the south with a short period, but poor conditions. That’s a no-go. Wednesday and Thursday the 2nd and 3rd are marginal at best. Then Friday the 4th of September – morning has a small 2ft swell from the south with offshore wind from the NW, 9-second period, but combined energy is weak (117). It’s clean but tiny.
The next week is quieter. The real standout in the second week is the 7th and 8th of September. Monday the 7th has swell building to 7ft from the ENE, 8-second period, combined energy 652, but the swell is too big for this break according to the guidance. Tuesday the 8th is even bigger – 10ft from the ENE, 9-second period, combined energy 2613, glassy wind. That’s massive and only for experts, but if you’re experienced and the break handles it, that could be a special session. The rest of the second week is mostly onshore winds and marginal conditions, but the 11th of September morning shows 6ft SSE swell, 13-second period, combined energy 1496, and clean cross-off wind. That’s another quality session for experienced surfers.
Water temp is about average for the time of year, nothing unusual.
The break is Mocambique, an exposed spot, fairly consistent, with optimum swell from the SE. Crowds are sometimes an issue, but nothing to stress about.
Rusty signing off.

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.
