The Lowdown
Alright, mate, Rusty here. Let’s break down what’s going on at Mocambique for the next 16 days.
It’s a bumpy start, then a lot of wind and chop, but the back half of the period is where the real juice shows up. Water temp is 19°C right now, which is dead average for this time of year, so no surprises there.
First up, Monday 31 August afternoon: glassy, 1.1m ENE swell, light northerly airs, combined energy of 303. That’s weak, but clean – a longboard kind of day.
Then we get a rough patch. From Tuesday 1 September through to Sunday 6 September, it’s mostly cross-onshore wind, moderate to fresh, with stormy weather – heavy rain, risk of thunderstorms – and the swell is messy. Swell heights are around 1.4m to 1.5m with short period, so it’s poor. Combined energy sits in the moderate 300–400 range, but the wind kills it. Monday 7 September is more of the same: cross-onshore, choppy, not worth suiting up.
Things turn on Tuesday 8 September. Morning goes glassy with a light NE breeze, 1.4m SSE swell, combined energy of 389. The sea is clean. Wednesday 9 September is the real standout: morning is cross-off with a 0.8m SSE swell, 12-second period, 456 combined energy. The afternoon is even better – 1.1m SSE swell, 11-second period, 635 combined energy, cross-off northerly winds. Very good, clean, proper lines.
Thursday 10 September morning is a gem – glassy, 1.8m east swell, 8-second period, 526 combined energy. Punchy and clean. The afternoon gets too big for the break at 2.4m and 889 combined energy, with cross-off wind. For the experienced, it’s powerful, but it’s pushing the limits.
Friday 11 September and Saturday 12 September are back to cross-onshore and marginal, so skip them.
The big one is Sunday 13 September. Morning has offshore NNW wind, 2.3m S swell, 10-second period, combined energy of 1351 – that’s strong. Afternoon is 2.4m SSE swell, 1426 combined energy, cross-off NNE wind, clean. This is a serious groundswell, but it’s too big for the break. Experts only, and you’ll need the right tide.
Monday 14 September is still very good – 2.0m SSE swell, 870 combined energy, clean cross-off winds. Tuesday 15 September morning is another beauty: 1.8m SE swell, 12-second period, 904 combined energy, offshore NNW wind. The afternoon gets a bit cross-onshore, but the morning is the pick of the second week.
Best bets: afternoon of 9 September, morning of 10 September, and morning of 15 September. The big swell on 13 September is for the brave. Crowds are possible at Mocambique, so time your sessions for the clean windows and you’ll be smiling.
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.
