The Lowdown
G'day, Rusty here. Let's talk about the surf ahead for Mocambique. The water temperature is sitting at 65°F, which is about average for this time of year, so nothing unusual there.
The next 16 days start off a bit slow. We've got some small, short-period ENE swell coming through at around 5ft to 7ft, but the wind is mostly cross-offshore, which keeps things clean. The combined energy is moderate, hitting 595 on Sunday morning, but the swell period is only 8 seconds, so the waves will be a bit soft and weak. Honestly, it's nothing to write home about through the early part of the week. Monday and Tuesday look marginal, with the best early chance being Sunday morning with light rain and a 12 mph NNE cross-off breeze. The waves will be around 7ft from the ENE, but it's not going to be a standout.
The real action starts to build on Wednesday, 19th August. The morning looks glassy with a light NNW breeze at 3 mph, and the swell drops to 4ft from the ENE. The energy is weak at 222, but those glassy conditions will make for a clean, fun session for intermediate surfers. Thursday morning, 20th August, also offers some clean cross-off conditions with a 3ft to 3ft ENE swell, but the energy is still low.
Then there's a bit of a lull from Friday, 21st August, through to Saturday, 22nd August. The swell switches to the south, but the wind is onshore or cross-onshore, making things choppy and poor. The energy builds to 451 on Saturday afternoon, but with a 9 mph SSE onshore wind, it's not worth paddling out.
Now, here's the standout. Sunday, 23rd August, is the one to circle on the calendar. We've got a solid 10ft swell from the south, with a period of 8 seconds in the morning and 10 seconds in the afternoon. The combined energy is strong, hitting 1269 in the morning and 1876 in the afternoon. The wind is glassy in the morning with a 3 mph SSW breeze. This is a big, powerful swell, so it's definitely for experienced surfers only. The waves will be too big for beginners, and with that short period, it'll be a bit messy. Still, for the experts, it's the best on offer across the whole forecast.
The following week looks a bit mixed. Monday, 24th August, has a 7ft south swell with a longer 11-second period, but the cross-onshore wind at 16 mph kills it. The energy is still high at 994, but the wind makes it choppy. Things improve on Wednesday, 26th August, with a nice 5ft SSE groundswell pushing in with a 12-second period. The wind is offshore from the NNW at 3 mph, and the energy is strong at 866. This is a solid, clean option for intermediate surfers, with good shape and longer gaps between sets.
The final few days of the month see the swell drop back down. Thursday, 27th August, has a 6ft ENE swell with cross-off winds, but it's marginal. The real gem is Monday, 31st August, with a 3ft ENE swell, a 10-second period, and a light offshore NNW wind at 6 mph. The energy is moderate at 422, and it's clean and glassy. A great little session for a relaxed paddle.
So, the standout days are Sunday, 23rd August, for the big, powerful south swell for experts, and Wednesday, 26th August, for the clean, long-period groundswell. Keep an eye on the forecasts, as the long-range stuff can be a bit less certain.
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.
