The Lowdown
Alright, Rusty here, let’s take a look at what’s coming our way.
Right off the bat, the first few days are a bit of a mixed bag. We’ve got some inconsistent, short-period swell – around 5 to 6 feet from the ENE, with periods only 8 seconds – and it’s being hit by cross-offshore winds, which keeps things clean, but the quality is only marginal. Monday the 17th and Tuesday the 18th offer some surf but nothing that’ll get the heart pumping. Those early morning sessions might be worth a quick paddle, but the combined wave energy is moderate, in the 300-600 range, and it’s just not that exciting.
From Wednesday the 19th through Friday the 21st, things go downhill. The swell drops and the winds turn onshore or cross-onshore, giving us poor conditions. You’re better off doing something else those days.
Now, Saturday the 22nd brings a change. We’ve got a new S swell rolling in with a period of 10 seconds, and Saturday morning it’s dead glassy – zero wind. The wave energy is moderate (387) and the swell is 4 feet from the south. That’s a good sign for clean, lined-up waves. The crowd factor says “sometimes” so expect some company, but for a Saturday morning session, this is the best bet in the early part of the outlook.
The real standout, though, hits on Sunday the 23rd. Mocambique is going to see a solid 7-foot swell from the south in the morning, with a period of 9 seconds. The combined energy jumps to 777 – moderate to strong. And the wind? Totally glassy. This is big, clean surf. But I gotta warn you, at 7 feet, this is edging into expert territory. It’s not a day for beginners. The afternoon pushes to 8 feet with a much longer 11-second period and energy over 2000 – that’s powerful. But with a cross-shore wind, it’ll be a bit bumpy. Still, this Sunday morning is the pick of the entire outlook: solid size, glassy conditions, and a south swell at a break that loves SE swell.
Monday the 24th is a write-off – too big (10-foot S swell) and strong onshore winds wreck it. That afternoon even with the swell dropping to 8 feet, it’s still onshore and messy.
Tuesday the 25th afternoon shapes up nicely for a smaller session: 5-foot SSE swell, 11-second period, and glassy conditions. Wave energy is moderate (493). Clean and fun, but nothing huge.
The last real highlight is Sunday the 30th through Monday the 31st. Sunday offers 4-5-foot SSE swell with a 10-second period and glassy winds both morning and afternoon. Combined energy is 650-688. That’s clean, fun, punchy surf. Monday the 31st morning brings a 4-foot SE groundswell with a very long 12-second period, offshore wind, and clean conditions – perfect for points or reefs. The energy is strong (577). But by Monday afternoon the onshore kicks in and spoils it.
Overall, the best session on offer is Sunday morning, August 23rd – glassy, solid 7-foot south swell, with moderate-strong energy. If you’re experienced, that’s your day. For a smaller, cleaner option, go for Sunday August 30th.
Stay sharp, and keep your board waxed.

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.
