The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Mocambique.
First up, the water temp is sitting at 66°F, which is bang on average for this time of year – no surprises there.
Straight off the bat, we've got a bit of a lull. Wednesday and Thursday are looking pretty ordinary with small, weak wind-affected swell, so you're not missing much. The first real sign of life comes in on Saturday morning, the 22nd of August. We'll see some chest-high swell (6ft) pushing in from the south, but it's going to be a bit bumpy with a cross-onshore wind, so keep your expectations in check. The combined energy is moderate (541).
Sunday the 23rd sees a bit more size, around waist-to-shoulder high (5ft), and that south swell picks up some serious period, hitting 11 seconds. That's a touch of groundswell, but it's still a little ugly with the wind, so it's not the one to get amped for.
Now, for the best of the bunch. Monday the 24th of August is a massive standout, but it's a serious one. We're looking at a solid 8ft south-southeast swell with a very long 13-second period and combined energy readings of 2229 – that's strong. The wind is light and offshore, so the lines will be clean. But here's the kicker: this is a serious amount of water for Mocambique. It's going to be way too big for beginners. This is expert-only territory, and you'll need to know what you're doing. The sheer power will be something else.
After that, things settle down a lot. Tuesday the 25th is a much better bet for the average surfer. We get a 5ft south swell with a 12-second period, and the wind is light and cross-offshore, keeping the face clean. Combined energy is still decent (804). This is the real sweet spot – good shape, fun size, and clean conditions. The crowd factor is "sometimes", so keep an eye out, but it'll be worth it.
The following days drop off in size, with some clean but small surf mid-week, before a bit of a bumpy, rain-filled spell hits from the end of August into early September. There's a brief moment of glassy conditions on the 30th of August, with waist-high (3-3ft) south swell, but it's small.
The second week into September looks messy, with a lot of onshore wind and rain. There's some size, with a 6ft east-northeast swell on the 1st, but the wind is all wrong, making it choppy and poor. The 2nd of September has a bigger south-southeast swell (6ft) but that's also accompanied by choppy wind.
To sum it up: if you're an expert, circle Monday the 24th of August on your calendar for a serious, powerful session. For everyone else, Tuesday the 25th of August is your best bet for clean, fun waves. The rest of the window is a bit of a mixed bag, with the end of the first week offering the best conditions.
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.
