The Lowdown
Alright, let’s break down Mocambique in feet and miles per hour.
The first week and a half is mostly a mess of bumpy, onshore slop, but there are a couple of windows that could be magic if you time it right. Water temp is 66°F, which is about average for this time of year, so no surprises there.
Starting Sunday, August 30th, it’s a dud. A 4ft ESE swell with a short 8-second period, and a cross-on SSE wind at 6 mph. Just leave the board in the car.
Monday, August 31st, starts with light rain and a 5ft ENE swell, still cross-on. But then Monday afternoon, the wind drops to glassy. You get a 5ft ESE swell, period only 7 seconds, so it’s not gonna be a gem, but glassy is glassy. The combined swell energy is moderate (362). That’s your first real chance.
Tuesday, September 1st morning is clean with a cross-off NNW breeze at 9 mph and a 5ft ESE swell, period 8 seconds. Energy is moderate (406). It’s okay, but not a standout.
Wednesday the 2nd and Thursday the 3rd get blown out with onshore winds and chop. Friday the 4th is tiny.
Then we get a big, messy south swell starting September 5th. Saturday afternoon sees a 10ft S swell with a 7-second period, but the wind is a strong cross-on from the S at 16 mph. The combined energy is very strong (1057). This is a washing machine—better for kitesurfing. Sunday the 6th is similar, 7-8ft S swell, still cross-on and lumpy.
Now, the real standout. Monday, September 14th morning. We’ve got a 8ft ESE swell, period 9 seconds, with a light cross-on S wind at 6 mph. The combined energy is strong (927). The wave comment says "wind and tide favorable, but the swell is predicted to be too big for this break." Over 8ft, that’s expert-only territory. The swell direction (ESE) is a good match for the optimum SE. The wind is light enough to keep it clean. This is the biggest, most powerful swell of the run. If you’re an experienced surfer and you’re out there on the 14th morning, you’ll have a serious session.
The 14th afternoon and 15th are also too big, so the window is tight.
The week before, there’s a smaller, cleaner option. Friday, September 11th morning is glassy, with a 4ft SSE swell, period 10 seconds. Combined energy is moderate (432). That’s a fun, clean, easy day for intermediates. The 10-second period gives it some push, and the glassy wind makes it silky.
So, to sum it up: Experts, lock in Monday, September 14th morning. For a more mellow session, Friday, September 11th morning is your best bet. The rest of the 16 days is mostly onshore junk.

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.
