The Lowdown
Alright crew, Rusty here. Let’s break down the next couple of weeks.
The water is sitting at 67°F, which is normal for the season.
The first few days are a total loss. The south wind is cross-on, making everything choppy and messy. Friday the 4th through Sunday the 6th is a real struggle. The swell builds, but the wind just gets worse, especially Sunday afternoon with a 2.5m swell and a 22 mph south wind. The combined energy is strong (1136), but it’s all blown out. You’d have more fun on a kiteboard.
Monday the 7th is still nothing special, just marginal, messy waves.
Here’s the good news. Tuesday the 8th is where it turns. The morning is glassy with a 1.2m SSE swell – clean as a whistle, with moderate energy (416). The afternoon goes cross-off with a light breeze. That’s a solid session.
But the real standout is Wednesday the 9th. The swell goes ENE at 1.8m, staying clean with a light cross-off breeze. The combined energy is moderate (550). This is the best of the run: clean, good shape, and the swell direction is exactly what Mocambique likes. It’s not a giant day, but it’s a quality day. Crowds are likely, as it’s a fairly consistent spot.
Thursday the 10th morning is also glassy with a 1.3m ENE swell – another good window, just a touch smaller.
After that, the weekend of the 12th and 13th is smaller and cleaner, but nothing special. Then Sunday the 13th gets ugly again with a big 3.0m south swell and a fresh onshore wind – a total mess.
The next week is mostly a bust. Monday the 14th through Wednesday the 16th has a big, long-period groundswell (13 seconds) from the SSE, but it’s all cross-on wind. The energy is huge (over 1000), but the wind ruins it. This is a powerful swell that would be epic at a point break, but with the onshore wind, Mocambique is just choppy.
By Thursday the 17th and Friday the 18th, the swell drops to small and weak. There’s a brief window on Saturday the 19th morning with a clean 0.9m S swell and light cross-off wind, but it’s a long way off and the energy is weak (369). Not a day to plan around.
So, the verdict: The first week is rough. Lock in Wednesday the 9th and Thursday the 10th. That’s your best chance at clean, fun waves. The second week is a coin flip – small and clean, or big and blown out.
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.
