The Lowdown
Right then, folks, Rusty here. Let's have a look at what's on the cards for Muizenberg.
We've got a mixed bag over the next couple of weeks. The first few days are looking pretty grim, with a strong onshore flow and a fair bit of chop making it tough going. But don't write it off just yet, because there's a real sweet spot shaping up towards the end of the month that should make the wait worthwhile.
The water is sitting at 57°F, which is a solid 3°F colder than the long-term average for this time of year. So, you're going to want a decent wetsuit, no question.
The older, longer-period swell due in around the 22nd of August looks promising. The later part of the month, starting with the 26th, is where the real clean waves are. The 26th of August, Wednesday afternoon, is looking like a standout. We've got a solid 5ft of SW groundswell hitting the beach, with a gentle offshore wind from the NW. The combined energy of all swells directed here is a solid 1010, making for a moderate wave energy. The water is expected to be clean, and these conditions are just begging for a good session. It's a bit of a session for the more experienced crowd, as that swell is running with some power.
The 27th of August, Thursday afternoon, is another absolute gem. The wind goes glassy, with a light SSW breeze, and the swell is a clean 4ft from the SW. The period is a very long 15 seconds, which is proper groundswell. This will likely be a bit too straight for the beach itself, but it should set up beautifully for a more westerly take-off spot. The energy is moderate at 663, and the glassy conditions are a massive plus.
Then, on the 1st of September, Tuesday morning, we get a glassy calm with a 4ft SW swell. The energy is 773, and it's clean as a whistle. Another top pick for those who want a smooth session.
The first week of September looks like it gets messy again, with a big 12ft swell on the 3rd, but that's going to be blown out by strong onshore winds. That one is definitely for the experts only, and even then, it's going to be a battle.
So, if you're looking for the best, target the 26th of August afternoon, the 27th of August afternoon, and the 1st of September morning. Those are the windows to circle in the calendar.
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.
