The Lowdown
Alright, Rusty here again, giving you the same outlook but in feet and miles per hour.
For Muizenberg, the water temp is 57°F, which is about 3°F colder than usual for this time of year. That’s a noticeable chill, so layer up.
Today, Tuesday 1st September, we get the biggest swell of the run—a 8ft SW swell with a 13-second period, carrying a strong 1831 combined energy. But the wind is a cross-on from the SSW at 6 mph, so it’s messy and marginal. Not the cleanest start.
The rest of the week into the weekend is a total loss. From Thursday 3rd through Saturday 5th, we’ve got strong onshore winds gusting up to 31 mph and short-period, choppy windswell. The energy drops, and the surf is poor. That’s a solid three-day gap with nothing worth paddling for.
Sunday 6th brings a 17-second groundswell, but it’s still onshore. All that energy (1323) is wasted.
The first real standout is Monday 7th September. The wind swings offshore from the NNW at 9 mph, and the swell is a clean 4ft from the SSW with a 13-second period. Combined energy is 564. It’s glassy, clean, and perfect for a mid-range session. This is the best early window.
Tuesday 8th is similar with a 3ft swell, but the afternoon goes cross-offshore. Still fun, but not as good as Monday.
Then another dry spell from Thursday 10th to Saturday 12th, with onshore winds or tiny, 3ft waves. The 12th has a glassy moment, but the swell is barely 3ft.
Now, for the long-range call. Sunday 13th September is the standout. The early morning shows a 4ft SW swell with a 15-second period, and the wind is offshore from the NW at 12 mph. Combined energy is a strong 1123. This is excellent for experienced surfers. The long period is a proper groundswell. Muizenberg can get crowded, so keep that in mind.
After that, Monday 14th gets hammered by onshore winds again, and the final day, Wednesday 16th, shows a building 6ft SW swell with a 16-second period, but the wind is onshore from the SE. Marginal again.
So, your best bets are Monday 7th September for clean, fun waves, and Sunday 13th September for a more powerful, groundswell session—but that one’s a week and a half out, so it’s a bit less certain. The first week is windy, so pick your moments.
Rusty.

Information about the Muizenberg Surf forecast
The above surf forecast table for Muizenberg provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Muizenberg can be found by selecting the local surf guide option on the grey menu. Our Muizenberg 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 (Muizenberg) 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 Muizenberg 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.
