The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you. This is a tough one. We’re looking at Muizenberg over the next couple of weeks, and honestly, we’re in for a long dry spell. The first real chance of a surf doesn’t even show up until the 16th of September, so we’ve got a big gap of quiet, messy conditions to sit through first.
The bone dry period kicks off Monday the 7th. The swell is tiny and the wind is cross-on, so the water’s sporting a bit of a chop. Tuesday the 8th through to the 11th, the waves drop off even more, barely a ripple with a light cross-onshore breeze. The water is seriously cold right now, sitting at 54°F, which is a massive 6°F colder than normal for this time of year. That’s a real shock to the system. The wind cranks up strong from the SE on the 11th, and while there’s a bit of size, the period is short at 7 seconds, making for bumpy, blown-out conditions. That pattern of strong, onshore wind continues right through to the 15th, with the swell energy bouncing around but never lining up with decent wind. The morning of the 15th brings a strong offshore, but the swell is only 3 ft, so it’s clean but hard to get into.
Now, the standout. Mark your calendar for Wednesday the 16th of September. This is the only real window. We’ve got a solid 10 ft of swell rolling in from the WSW with a lovely long period of 16 seconds, giving it that real groundswell push. The combined energy is a massive 4694, so there’s serious power. The morning looks best with a moderate offshore breeze from the NW, keeping the faces clean. This is a big swell, well over 8 ft, so this is expert territory only. Muizenberg is exposed to the swell, and with that long period, the waves will be lined up but the sets will be widely spaced. The afternoon swings around to a cross-shore wind, so the morning is your window. With crowds listed as “often” here, expect plenty of company for this one.
After that, it’s a mess again. The 17th and 18th get hammered by strong SE winds again, making the 8 ft+ swell a total washing machine. The 19th calms down a bit, but the swell is small and mixed. The 20th and 21st show a bit more size but cross-onshore winds wreck the quality. The 22nd finishes the run with an 8 ft swell and onshore wind, so it’s a no-go.
In short, we’ve got a long wait for one solid day. The 16th is the only game in town, and it’s a big one for the crew who can handle it. Keep your eyes on the forecast, because this stretch of poor conditions can’t last forever.
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.
