The Lowdown
Alright, let’s break this down for Mocambique in feet and miles per hour.
The first few days are nothing to write home about. Thursday the 20th and Friday the 21st give you tiny 2-3ft ENE swell with cross-off winds and such low energy (135) it’s basically flat with a bump. You can paddle out, but you won’t be smiling.
The first real standout pops up Monday August 24 – but it’s a tricky one. A 7-8ft S swell rolls in with moderate energy (2720) and the wind is favorable, but the forecast says it’s simply too big for this break. If you’re a seasoned local and know where to sit, maybe. For most people, it’s a watch-from-the-beach day.
Now Tuesday morning August 25 is the one. Winds go glassy at 3 mph from the WNW. You’ve got a clean 6ft SSE groundswell with a 13-second period and energy around 1144. That’s proper groundswell rolling in, clean and lined up. The direction (SSE) fits the optimum SE angle for Mocambique nicely. This is excellent surf for experienced surfers. Crowds can be a factor, so get out there early and you’ll score.
Midweek, Wednesday August 26 and Thursday August 27 keep that SSE swell going at 5-6ft but with cross or cross-off breezes. Thursday morning on the 27th is noted as “very good,” but it’s smaller than Tuesday.
Friday August 28 and Saturday August 29 see the swell shift to ENE with a shorter period (8-9 seconds) and lighter energy (500-600). Winds stay mostly cross-off, and Saturday morning and afternoon are both tagged as “very good” for clean, smaller conditions. Good for a funboard or a log.
From Sunday August 30 into early September, it goes downhill. Cross-onshore winds, lumpy chop, and waist-high waves with poor conditions. There’s a real lull until Wednesday September 2, when a S groundswell returns with 6ft waves and 13-second period and energy hitting 1811, but cross-off winds keep it from being a standout.
The bottom line: Tuesday morning August 25 is your best bet – glassy, 6ft, clean, groundswell. The rest is mostly average with a couple of clean mornings for smaller boards.
Rusty out.

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.
