The Lowdown
Right then, let’s have a look at what’s on offer for Mocambique over the next couple of weeks. Straight up, there’s a bit of a rough patch to get through before things clean up. The first few days are pretty ordinary, with a persistent cross-onshore wind messing things up. Don’t get too excited about the 12th of September – we’ve got a 7ft S swell, but it’s short period at 7 seconds and the wind is a 19 mph cross-on. It’s going to be lumpy and messy, with moderate wave energy (491). The water’s sitting at 64°, which is a bit colder than normal for this time of year.
Sunday the 13th through to Wednesday the 16th stays poor or marginal. You’ll see some S swell around 5ft to 6ft, but the period is short, and the wind is mostly cross-on. Not worth paddling out for.
The first real standout comes on Thursday the 17th. The morning looks magic – glassy conditions, with a 6ft S swell that has a nice 11-second period, giving it good energy (698). The wave quality is expected to be excellent, and that northwest offshore wind will have the faces clean. This is the best bet early on.
Friday the 18th morning is also a solid option. A 3ft S swell with a 10-second period, and a gentle offshore wind from the NNW making for clean surf. The combined energy is moderate at 341. It’s a smaller day, but clean.
After the 19th, we have a few days of cross-on junk again, but there’s a glimmer on Sunday the 20th afternoon – a 5ft E swell with a 7-second period, and a light offshore wind from the NW cleaning it up. Not the best period, but better than what’s around it.
The following week from the 21st to the 22nd is decent, with cleaner conditions and east swells in the 5ft to 6ft range, periods around 8 to 9 seconds. Light offshore or cross-off winds keep things tidy. Moderate energy builds into the 400s.
The real standout of the whole outlook is towards the end of the period: Friday the 25th through Sunday the 27th. Friday morning starts glassy with a 4ft S swell, 12-second period, and excellent quality. The afternoon sees a 5ft S swell pushing 13 seconds, with very good quality and clean conditions. On Saturday the 26th, we’ve got a 5ft S swell with a 12-second period, cross-off wind, and very good surf conditions expected. The energy is strong at 903. This long-period groundswell will wrap in nicely here at Mocambique, and as a point break, it’s going to handle that long period swell well. Keep in mind, crowds can be an issue here, so get there early.
Sunday the 27th morning is another cracker – 6ft E swell, 7-second period, but with a clean offshore wind from the NNW. Very good surf conditions are expected. The afternoon, however, gets blown out again by a 19 mph cross-on.
Overall, the best windows are Thursday the 17th morning, and then the Friday 25th to Sunday 27th stretch, with the 25th and 26th being the absolute best on offer. Go get it.

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.
