The Lowdown
Alright, this is Rusty. Let’s break down what’s happening at Mocambique.
First thing’s first – the water temp is right around average for this time of year, nothing unusual. The start of the forecast is weak and messy. For the first few days, we’ve got small, poor-quality waves with cross-onshore breezes making everything choppy. Monday and Tuesday of this week are a total washout – don’t bother.
Wednesday the 16th morning pushes up to about 5ft from the south, but it’s short period (8 seconds) and still cross-on, so the surface is ugly.
Now, here’s the real gem. Thursday, the 17th of September, morning is your best call. The wind is dead calm – glassy conditions. You’re looking at a clean 5ft south swell with a 10-second period. The energy is solid, in the moderate range (432). This spot is exposed to that south swell, so it’ll be working. Crowds are just “sometimes,” so you might have some company but nothing crazy. This is fantastic for an intermediate surfer.
Friday the 18th morning also cleans up with a light offshore breeze from the north, but the swell drops to about 3ft (258 energy). Still a fun, mellow option.
Then we get a big pulse of energy over the weekend. On Saturday the 19th and Sunday the 20th, the swell swings around to the ENE and jumps up to 8ft to 8ft. That’s big. The period is short, 8 to 9 seconds, and the energy is strong (685 to 834). The comment says it’s too big for this break. This is for experts only. Beginners, stay off the water.
The next window of clean conditions is Monday the 21st of September morning – another glassy session with a 6ft ENE swell at 9 seconds (463 energy). Solid and clean again.
The second week gets patchy. Tuesday 22nd morning is glassy with a 5ft east swell. Thursday 24th morning has a nice offshore wind from the NNW with a 5ft east swell (325 energy). That’ll be clean. After Friday the 25th, it drops right off into tiny, weak, poor-quality surf. From the 26th onward, there’s nothing worth paddling out for – a long quiet spell.
The standout to pin on your board is Thursday 17th September morning at Mocambique. Glassy, 5ft from the south, clean lines. That’s your session.
Rusty.

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.

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.
