The Lowdown
Right folks, let’s have a look at what’s cooking. We’re at Milnerton, and there’s a solid run of groundswell coming through, but you’ve gotta pick your moments. The water’s sitting about average for this time of year, so no surprises there.
The action kicks off Sunday morning, September 6th. A nice clean 7ft SW groundswell with a very long 18-second period rolls in – that’s proper energy (2865). The ESE offshore breeze will have things clean and lined up. But with that size and period, it’s a beast for experienced surfers only. The break is fairly exposed, so it’ll handle it, but it’s a big one. The standout of the whole run is Monday morning, September 7th. Glassy conditions, 7ft SW swell with a 14-second period, and the energy is still pumping (1504). That’s a window of pure, clean surf.
Tuesday morning, September 8th, things back off a touch – 3ft WSW swell, but it’s glassy again, so if you want a smaller, cleaner board, that’s your window.
Thursday morning, September 10th, another big pulse hits: 8ft WSW swell, 15-second period, and a gentle ESE offshore. That’s 3081 of energy – powerful, but only for the experienced crew.
The second week gets a bit messy. There’s still size, like 10ft on Sunday September 13th and 12ft on Tuesday September 15th, but the wind swings onshore and it gets lumpy. That 13ft on Tuesday afternoon with a 22 mph NW wind? That’s kite-surfing territory, not paddle surfing.
Thursday September 17th morning sees a clean-up: 10ft SW swell, 13-second period, and a SSE cross-off. That’s a big, clean wave for experts.
Friday September 18th morning is another golden moment: 8ft SSW swell, 12-second period, with a clean ESE offshore. That’s a solid, clean session.
The very end of the run, around Sunday September 20th, drops to 4ft and glassy – small and clean for a fun session.
The best on offer? Lock in Monday September 7th morning for the glass, the size, and the energy. Friday September 18th morning is a close second for that clean offshore push.

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