The Lowdown

Alright, let’s get into it.

The next 16 days are a mixed bag, but there are some real standouts if you’re patient. The water temp is sitting at about 65°F, which is about average for this time of year, so nothing wild there.

Let’s start with the first decent run. Monday the 17th kicks off with some small but rideable swell at Mocambique. The swell height is around 6ft from the ENE, period a short 8 seconds, so it won’t have much punch. The wind is cross-off from the north, which keeps it clean, but combined energy is only 731 (moderate). It’s surfable, but not a standout.

Tuesday the 18th picks up a little. Morning offers 5ft ENE swell with a light north breeze, clean conditions, and a score that suggests it’s worth a look. The energy is down to 309 (weak), so it’s not powerful, but it’s a nice mellow session.

Wednesday the 19th and Thursday the 20th are pretty flat. Swell drops to 4ft and 3ft, wind turns onshore or cross-onshore, and conditions are poor. Not worth paddling out.

Friday the 21st morning brings a brief window. Offshore wind from the WNW, 4ft ENE swell, 7-second period – clean but weak. The energy is only 162 (weak). It’s okay, but nothing to get excited about.

Then we hit a gap. Saturday the 22nd and Sunday the 23rd have some swell, but the wind is messy – cross-onshore, choppy, and the swell direction shifts south. Not great.

Now for the real standout. Sunday the 23rd morning – glassy conditions, 6ft swell from the south, period 11 seconds, and energy at 676 (moderate). The wind is calm, the water is clean, and the swell direction is a solid match for Mocambique’s optimum SE direction. This is the best session of the first week.

Monday the 24th gets bigger – 8ft south swell, 12-second period, energy up to 1404 (strong) – but the wind is cross-onshore and choppy, and the swell is too big for this break. Keep it for the experts only.

Tuesday the 25th morning is another beauty. Offshore wind from the NW, 6ft south swell, 12-second period, and energy at 961 (strong). Clean, powerful, and well-shaped. This is a top pick.

Wednesday the 26th and Thursday the 27th are smaller and less consistent. Swell drops to 4ft and 6ft, but the wind is good. Worth a look if you’re keen, but not a standout.

Friday the 28th brings back a strong morning session. 6ft ENE swell, 9-second period, north wind, clean, and energy at 539 (moderate). The afternoon is even better – 5ft ENE swell, 9-second period, light north wind, energy at 816 (moderate). This is a solid day.

Saturday the 29th morning is clean with 5ft ENE swell, 9-second period, NNW wind, energy at 504 (moderate). Good, but the afternoon turns cross-onshore and gets choppy.

Sunday the 30th and Monday the 31st are a different story. Swell builds to 10ft on Monday morning from the south, energy at 1436 (strong), but that’s expert-only territory. The wind is light, but the size is too much. The afternoon session on the 31st sees 8ft SSE swell, 14-second period, energy at 2292 (very strong) – a huge, long-period groundswell. That’s only for the experienced, and the river mouth or reef might handle it better than the beach.

Tuesday the 1st of September drops back to 6ft SSE swell, 12-second period, energy at 1245 (strong). The wind is onshore, so it’s messy.

Bottom line: The best windows are Sunday the 23rd morning and Tuesday the 25th morning. Both have clean conditions, solid swell, and good energy. The end of the month has some serious size, but it’s for experts only.

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.
