The Lowdown
Alright mates, grab a coffee, it’s Rusty here. We’ve got a bit of a slow start on offer over the next couple of days at Muizenberg. The surf is barely limping along with a weak cross-shore breeze and messy lines, so I’d sit those out. The energy just isn't there for a proper session.
Things start to shape up properly from Thursday morning (13 August). We’ve got a pulse of southwest swell pushing in at 5 ft with a solid 17-second period. That’s proper groundswell, folks. The wind is light and crossing just offshore, making for clean, walled-up faces. The combined energy is pumping hard at 1685 – that’s strong stuff. This looks like the standout window for anyone who knows what they’re doing.
Friday (14 August) keeps the good times rolling with offshore winds from the northwest and a still-juicy 4 ft of swell. Periods drop a bit, but the combined energy is still in the moderate range around 661. Saturday morning (15 August) is an absolute gem for the early crew – glassy as a mirror, a light 4 ft of swell from the WSW. Get on it before the onshore trash shows up later.
The second half of the month is more of a waiting game. There’s a decent pulse on Monday (17 August) – 5 ft from the WSW with glassy conditions in the morning and clean cross-off in the afternoon. The combined energy climbs back up to 1009, so that’s a solid session if you can sneak out. By the weekend of 22-23 August, the wind cranks onshore from the SSE and ruins the waves – those are write-offs.
The last few days of August fade to tiny leftovers. The morning of Wednesday (26 August) is glassy but with only 2 ft of swell. The combined energy is a weak 77 – you’d be better off paddling a pool. For this stretch, Muizenberg is a beach setup and with the onshore wind, it starts looking more like a kite session than a surf.
So, to wrap it up – the best on offer is Thursday morning (13 August) for experienced surfers with that long-period, clean 5 ft SW swell. Saturday morning (15 August) is the call for all levels wanting silky conditions and a friendly 4 ft. After that, pick your windows carefully. The water temp is about average for this time of year.
Stay stoked, but stay patient.
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.
