The Lowdown
Alright, let’s get into it. It’s Rusty here, and I’ve been staring at the charts for Mocambique. To be honest, mate, the start of this run is a bit of a letdown. We’ve got a few days of small, messy, junk to wade through before things finally start to look up.
We’re talking about Mocambique, a spot that’s exposed to swell and likes it from the SE. For the first few days, from Wednesday the 19th through Friday the 21st of August, the surf is pretty ordinary. Small waves in the 3 ft to 4 ft range, mostly from the ENE, with short, weak period (7-8 seconds). The wind is often cross-on or onshore, and the energy is low. It’s just not worth paddling out for; you’ll be fighting bumps and ripples.
Saturday the 22nd morning is interesting, though. We get a jump to a 6 ft swell from the south with a bit more push. The wind is cross-shore, which is okay, but the report calls it “marginal” due to tide. It’s a look-see at best.
Now, here’s a little gem. Sunday morning, August 23rd. The wind goes *glassy*. Dead calm. The swell is only about 3 ft from the south, but it’s got a nice long period of 11 seconds (that’s groundswell energy) and solid moderate energy. That’s the kind of glassy surface that makes even a small wave feel like a million bucks. The afternoon goes onshore and messy again, so get on it early.
But the real stand-out, the one you’ve been waiting for, is Monday, August 24th. We’ve got a proper pulse of swell hitting: 8 ft from the SSE with a very long 13-second period. The combined energy is massive. This is *not* for beginners. For experienced surfers, this is a pumping day, but be warned, the data says the swell might be too big for this particular break and could close out or be unruly. The wind is light cross-on, so it won't be perfect, but the power is there.
After that, the quality holds for a few days. Tuesday the 25th is a great call: 5 ft from the south, 12-second period, and a clean cross-off wind from the NNE. That’s a green flag for some proper lines. Wednesday the 26th also looks fun with a 6 ft NE swell, but the period drops back to 8 seconds (windswell) so it’ll be a bit more bumpy, though the cross-off wind keeps it clean.
The second week, starting around Thursday the 28th, gets messy again. Strong S winds and onshore conditions mess up a lot of the smaller ENE swells. There’s a brief window on Saturday the 29th with a clean 3 ft ENE swell and offshore NW wind in the morning – that’s a nice little session for a log or mid-length. The 30th and 31st are a write-off with heavy rain and fresh cross-onshore winds.
Overall, our best bets are:
1. Sunday morning, August 23rd – Small, clean, glassy. Perfect for a longboard. Crowds are *sometimes* a factor here, so you might have company.
2. Monday, August 24th – The big one. Big south swell, expert-only, likely unruly but full of power.
3. Tuesday, August 25th – The best all-rounder. Clean conditions, decent 5 ft groundswell, and clean wind.
Water temp is about average for this time of year. Nothing weird going on there, so just your usual summer steamer or spring suit.
That’s the picture for Mocambique. Get the good ones while they’re clean.
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.
