The Lowdown
Alright, this is Rusty, and here’s the look at Muizenberg.
The first few days are a total bust. That SE wind is cranking at 28 mph on Friday, and it’s just blowing everything out. The water is running at 58°, which is a bit cold for this time of year. There’s swell, but it’s all messy and onshore. No dice.
Sunday the 6th, the wind drops to a gentle 9 mph from the ESE, but it’s still onshore. The swell is there, but the combined energy is 2069 (moderate to strong). It’s marginal. The afternoon gets a light breeze, but still onshore.
Monday the 7th is where we get a window. The wind goes NW at 6 mph, offshore. That’s the ticket. The swell is a clean 3ft from the WSW with a long period of 14 seconds. The energy is 709 (moderate). It’s not big, but it’s clean. The afternoon keeps it going with a cross-offshore wind and a 4ft SW swell. This is a good session for a beginner or an intermediate.
Tuesday the 8th is a glassy morning. Zero wind from the SW. The swell is tiny at 3ft from the SSW, period 11 seconds. The energy is low at 264 (weak), but it’s going to be smooth as glass. The afternoon gets a bit of a cross-onshore, so get out early.
Wednesday the 9th and Thursday the 10th are a step back. The wind comes onshore again, and the swell gets lumpy. The Thursday morning has a 6ft SW groundswell with 14-second period, and the energy is 1202 (moderate), but the wind is cross-onshore, so it’s choppy.
The next week is a rough patch. We’ve got strong onshore winds from the SE up to the 14th, with solid swell sizes (6ft to 7ft) but all blown out. The energy gets high, but it’s not surfable for paddle surfing.
The standout for the whole period is the 16th of September, Wednesday. The afternoon is a gem. Wind goes NW at 6 mph, offshore. The swell is 4ft from the SW with a very long period of 17 seconds. That’s a proper groundswell, and the combined energy is 1095 (moderate). The forecast says it’s excellent for experienced surfers. That long period will make for lined-up waves.
Then the 17th of September, Thursday, is the big one. The morning shows an 8ft swell from the SSW, period 12 seconds, with a cross-offshore wind. The energy is massive at 3526 (strong). The afternoon is even bigger: 7ft from the SW, period 17 seconds, and an energy reading of 7052 (very strong). The wind is cross-offshore. This is for experts only. It’s a powerful groundswell.
The 18th of September, Friday, is a warning. The morning shows an 12ft swell from the SSE. That’s too big for this break. The energy is 7466 (very strong). The forecast even says it’s too big.
So, the best bet in the short term is Monday the 7th and Tuesday the 8th for clean, small waves. The long-range standout is the 16th and 17th of September, but that’s a bigger, more powerful swell. Keep an eye on the wind.
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.
