The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
We’ve got a real mixed bag of a forecast coming up. The first couple of days are actually looking pretty sweet with clean conditions and some fun sized swell, but then things get messy. A big dirty southerly blow is gonna trash the place, and then we get a period of oversized swell that’s just too much for the spot. We’ll see a bit of a recovery right at the end of the window, but the middle part of the month is a write-off for a decent paddle.
The best session on offer is hands down the Tuesday morning, 8th of September. Mocambique is gonna be firing. We’ve got a nice 5ft of SSE groundswell (that’s 407 moderate energy) with a 10-second period, and the wind is a light offshore from the WNW at 3 mph. That’s the recipe for some clean, lined-up waves. Water temp is sitting right on 66°, which is bang on average for this time of year, so no surprises there. Get out there early, it’ll be worth it.
The other standout is the Wednesday morning, 9th of September. The swell is up a touch to 5ft, coming from the ENE with a shorter period of 8 seconds, but the wind is glassy. Dead flat. That’s a major positive. The combined energy is a solid 534 (moderate), so there’s plenty of push. Just be mindful that the short period will make for a bit more of a crumbly, less powerful wave than the day before.
Now, Thursday the 10th is still OK. It’s a bit smaller with 3ft of S swell, but the period is a long 12 seconds, which is proper groundswell and will give you some nice shape. The morning offshore (NNW, 6 mph) keeps it clean. The energy is still moderate at 502.
After that, it turns ugly. Starting Friday afternoon, the wind swings and picks up, and by Saturday the 12th, we’ve got a 10ft southerly swell with a fresh 19 mph cross-onshore wind. That’s a total mess. The energy is 1540 (strong), but it’s just too big and blown out. This is more of a kite-surfing setup than a paddling one. That continues all the way through to the middle of the following week with the swell staying over 7ft and the wind cross-on or onshore. That’s a solid 5-6 day gap of no good surf.
We get a glimmer of hope on the 17th of September. The wind goes glassy again on Thursday morning with a small 3ft easterly swell. It’s nothing special but it’s clean. The 18th of September Friday morning is also glassy with 4ft ENE swell, but the period is a short 6 seconds, so it’ll be a bit fat and weak.
The last few days of the forecast, heading into the 19th and 20th, we see big swell again. The 20th September Sunday morning is looking at 8ft of ENE swell with a long 9-second period and a light offshore wind. The combined energy is 1116 (strong to very strong). That is a lot of water. The problem is that at 8ft, that’s expert territory only. The wind is clean, but the size will be intimidating for most. It’s a promising but less certain call for the second week.
So, to wrap it up: get on it Tuesday the 8th or Wednesday the 9th of September. There’s a big ugly gap in the middle. The end of the window has size but is for the brave, and the very last days look messy again.
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. 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.
