Mocambique Surf Forecast and Surf Report

Alright, let’s get into it.

The next week and a half or so is looking pretty ordinary around here. Wave energy is moderate to strong at times, but the wind and the swell direction are just fighting us. We’ve got a big run of clean, cross-off mornings early on, but it’s mostly small and weak, then a whole lot of lumpy, cross-onshore junk for days. There’s a potential window late next week that could be the standout, but you’ll need to be patient. It’s not a period for the casual surfer; you’ll have to be keen.

Mocambique is the only break showing up to bat. The first real call is for Wednesday morning, September 9th. It’s glassy with a light NW breeze. Swell is a modest 3ft from the south at 12 seconds. Water temp is 65°, which is about 0.9° colder than average for this time of year – nothing weird, just a touch of autumn chill in the water. It’s a fairly consistent break, so the small stuff should still offer a few clean lefts and rights. Combined energy sits at a moderate 484. It’s a bit small, but the conditions will be clean and the long period south swell will have some push to it. This is a good one to warm up on.

Wednesday afternoon stays glassy with a cross-off breeze. The swell picks up slightly to 4ft from the SSE at 10 seconds, and the energy is still moderate at 496. Still decent, just not big.

Thursday morning, September 10th, sees a shift. A light NNW cross-off wind, but the swell drops and turns a bit, coming from the east at only 8 seconds. It’s 4ft and the combined energy is down to a weak-ish 318. The period is short, so it’ll be a bit crumbly and disorganized. Still surfable, but not great.

From Thursday afternoon through to Monday, the wind builds out of the north and then swings around to the south. The swell gets bigger – up to 8ft on Saturday afternoon – but it's all onshore, cross-onshore, and choppy. The energy readings are strong, like 713, 1270, 923, but it’s all that messy south, southeast wind swell. The guidance flags these as poor conditions. A lot of this run will be a battle. With that much swell and the wind howling cross-onshore, this setup looks like it could be more fun for the kite surfers than for us paddle surfers.

Tuesday, September 15th, offers a bit of a tease. A light cross-shore breeze in the morning and the swell is 6ft from the east at 8 seconds, energy at 672. But the period is short and it’s still a bit messy. It’s a marginal call at best. The afternoon turns ugly again with a 15 mph south cross-onshore.

Now, for the standout. Hold on for Thursday morning, September 17th. This is the one. There’s a complete glass-off, no wind at all. The swell swings back around to the SSE at 12 seconds, with a 5ft face. The combined energy is a solid 744. The forecast text says it plainly: expect very good surf conditions. This is a long-period groundswell, so it’ll have some real power and shape to it. Mocambique is an exposed spot, so it should handle this well. The afternoon even keeps a clean cross-off breeze with 5ft waves. This is your window. It’s a little over a week out, so it’s promising, but not set in stone just yet.

Friday the 18th is still worth a look, with a glassy morning and chest-to-head-high waves, but the swell is forecast to be 7ft from the ENE at a short 7 seconds. The energy is very strong at 1197, but the model notes it might be too big and unruly for this break. The period is just too short for a wave that size, and it could be a close-out mess. The afternoon cleans up with a cross-off breeze and 5ft waves, but the morning might be a bit of a washing machine. And that’s mainly it.

From Saturday the 19th onward, things fade away. The swell drops back to around 4ft, with mixed winds and mostly cross-onshore or very weak conditions. The energy numbers fall away too, down into the 100s and 200s. It looks like we might get another run of clean mornings from the 20th to the 23rd, but the swell is small, the period is short, and the energy is weak. It’s surfable but completely ordinary. Not worth getting excited about.

So, to wrap it up: there’s plenty of junk coming with that south swell, a few small but clean sessions early on, and then that Thursday the 17th looks like the day to make the call to miss work. It’s the only true standout in the whole run.
