The Lowdown
G’day, Rusty here. Let’s be straight with it – this run for Mocambique is a mixed bag. There’s some size early on, but it’s wonky. The real gem sits way out on the 28th of August, and a few days either side of that have some glimmers. The water’s sitting at about 65°F, which is pretty much what you’d expect for this time of year, no real shocker there.
The first real standout for a surf is the Saturday morning of the 15th of August. It’s small, 5ft from the SSE with a solid 12-second period, but the cross-on wind from the east at 6 mph is light, so it’s not too chopped up. The combined energy is moderate at 991. Not magic, but it’s a start.
Now, the Sunday the 16th of August morning is where things get interesting. The swell jumps to 7ft from the ENE, period is a short 8 seconds, and the wind is cross-off from the NNE at 9 mph. The combined energy is strong at 1167. This is a bit chunky and short-period – not a beginner wave at that size. It’s more for the experienced crew who can handle a bit of push.
The week after that goes quiet. There’s a gap of several days with nothing worth chasing – just small, ordinary conditions until Wednesday the 19th of August. That morning is a proper little highlight: glassy conditions, wind from the WSW at 0 mph, swell 4ft from the ENE, period 8 seconds. Combined energy is only 241 (moderate), but the glass makes it clean and fun. Crowds could be around at Mocambique, so you might want to get in early.
Then it gets messy again. Thursday and Friday the 20th and 21st of August are pretty flat and ordinary. The next big pulse comes on Sunday the 23rd of August, but it’s too big for this spot – 7ft from the S with a 13-second period, combined energy a massive 1593. That’s a wall of water, and with cross-on winds, it’s just messy and dangerous for anyone but experts.
Now, the real standout – the one to circle on your calendar – is Friday the 28th of August morning. Glassy offshore, wind from the WSW at 3 mph, swell 4ft from the ESE, period 7 seconds. It’s not a long-period groundswell, but the conditions will be clean as a whistle. Combined energy is moderate at 542. That’s the session for the week, no doubt.
The Saturday the 29th of August morning has another glassy window, with 5ft from the ENE, but the period is still short at 7 seconds. Worth a look if you missed the Friday.
Overall, Mocambique has a few moments, but the best bet is the 28th of August. Get it while it’s clean.
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.
