The Lowdown
Hey, Rusty here again, checking in on the surf for Mocambique. It’s a two-week story: first week is average, second week has a big window if you wait for it.
Water temp is about 66°F, which is spot on for this time of year.
Starting off, Wednesday the 19th is a no-go—cross-on wind, choppy, with a 3ft swell from the ENE. Weak energy (155). Thursday the 20th morning has a clean 3ft swell with a light offshore breeze, but it’s still nothing special. Friday the 21st is messy with a 4ft onshore south swell, and Saturday the 22nd has a bigger 7ft south swell, but it’s cross-on and choppy. Energy is moderate now (762), but conditions are poor.
Sunday the 23rd morning is a little better—5ft from the south at 11 seconds, but still cross-on. Energy is moderate (522). Monday the 24th is a big one. The swell hits 8ft from the SSE with a 13-second period, and the wind goes glassy in the morning. The energy is strong (2128). But it’s too big for this break—expert-only stuff. Tuesday the 25th morning is your standout. A solid 6ft SSE groundswell, clean with a cross-off NNW breeze, and energy is still strong (1057). This is the best of the period for experienced surfers. The swell direction matches the optimum SE perfectly.
After that, it quiets down. Wednesday the 26th morning is glassy again, but the swell is small at 4ft from the SSE. The rest of the week is small and clean but not exciting. There’s a gap of mediocre conditions from the 27th to the 30th, with small ENE swell and clean winds.
Then the first week of September goes downhill. The 31st and 1st bring rain and strong onshore winds—30 km/h (19 mph) from the south—making a mess of the 7ft swell. The 2nd and 3rd are worse, with fresh cross-on winds and lumpy, choppy conditions. At that point, a kite surfer might be better off.
So, bottom line: if you’re experienced, get out on Tuesday the 25th morning. The second week fades out, but forecasts can always shift.
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.
