The Lowdown
Alright, let’s break it down. We’re only looking at Mocambique here, an exposed SE-facing spot. The water temp is 18°, which is about a degree colder than usual for this time of year – so a bit chilly.
The first week starts off slow. Monday the 14th brings light rain and a gentle cross-onshore breeze. The swell is around 4ft from the south, period of 11 seconds, with moderate energy (505). It’s surfable but choppy. Tuesday and Wednesday stay in that marginal zone, with similar or smaller swell and the wind staying cross-on or onshore, keeping things messy.
Thursday the 17th is the real highlight. Thursday morning is glassy – zero wind – with a solid 5ft south swell and a longer 12-second period. The energy is strong at 566. That’s clean, proper groundswell. This is the best session of the week. Later Thursday and into Friday, the wind turns cross-off or cross, keeping it clean, but the swell drops off.
The weekend turns ugly. Saturday the 19th sees a rising ENE swell, but it’s short-period, wind-affected slop with moderate to strong onshore wind. The swell hits 7ft on Saturday afternoon, but with an 8-second period and choppy cross-onshore, it’s just a mess.
Now, into the start of the second week, Sunday the 20th is a big one. The swell is predicted to be 8ft from the ENE, with a very strong energy reading of 1154. The wind is offshore from the NNE at 12 mph, keeping the surface clean. But at 8ft, this is expert-only territory. The period is only 9 seconds, so it’s a windswell, but the size is the main factor. Monday the 21st is similar, with glassy conditions and a 7ft ENE swell (energy 717), but again, it’s likely too big for most.
After that, the swell settles. Tuesday the 22nd has some clean surf with offshore winds and 5ft from the east, but the period drops to 8 seconds. The rest of that week into the 25th sees smaller swell, around 2ft to 4ft, with clean cross-off winds but low energy. By Saturday the 26th, the energy drops to 84 – weak – with tiny 1ft surf. The last few days of the month see a slight bump back up to 4ft to 6ft from the south, but the wind turns onshore again, making it messy.
So, the honest take: Thursday the 17th morning is the standout. That 5ft south swell with glassy conditions is the pick – clean, consistent, and fun for intermediates. The Sunday the 20th and Monday the 21st have the biggest swell, but it’s only for experts, and the quality is questionable with the short period. For the rest, it’s a waiting game. The crowds at Mocambique can be a factor sometimes, but with the conditions as they are, it might not be too packed.

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.
