The Lowdown
Alright, let’s break it down. For the whole 16-day run, it’s all about one spot: Kleinmond. This is a reef break, exposed to the swell, and it likes a good SSE direction. Water temp is running 58°, which is a bit colder than normal for this time of year, so you’ll want a thick wetsuit.
The forecast kicks off with some messy energy. Tuesday the 18th has a solid 10ft SW swell, combined energy of 2715 (strong), but it’s blown out by a SE wind. Wednesday morning the 19th is also pretty average with a cross-onshore wind, but by Wednesday afternoon things clean up. The wind swings to a light cross-offshore, the swell drops a touch to 8ft from the SW, and it cleans right up. That’s a nice window for the more experienced crew, as 8ft at a reef takes some nerve.
Now, the real standout. Thursday the 20th. We’re talking a glassy, dead-calm morning with a 12ft SW swell rolling in – that’s a combined energy of 3732 (very strong). The wind is pure glass. However, for a reef break, that size is only for the experts. It’s going to be a big, powerful day. Crowds are possible here, so if you’re confident, dawn patrol will be the call.
After that, Friday drops right off to 5ft with some onshore slop, and the wind builds through the weekend. Saturday the 22nd morning is a write-off with 19 mph NW winds, but the afternoon shows some promise: a clean cross-offshore breeze with a 8ft SW swell (1140 energy). Sunday the 23rd and Monday the 24th are mostly cross-on messes, not worth the drive for the conditions.
There’s a gap of poor-to-average days until Wednesday the 26th morning. That’s another glassy session: 6ft WSW swell, combined energy 1139, and the wind is dead flat. Clean, smaller, and perfect for the intermediates. The energy is moderate but the waves will be tidy.
The following week looks interesting but a bit touch-ande. Monday the 31st afternoon shows a big 10ft SW swell with a very long 15-second period and a clean offshore NW wind blowing – combined energy 3712 (very strong). That long period is perfect for a reef like Kleinmond, giving it shape and power, but again, that’s big-wave territory only. Then into Tuesday September 1st, the morning holds a clean offshore with 8ft SW swell (1929 energy), a solid, cleaner option for the brave. The wind stays favorable through the first week of September, but the swell stays on the bigger side, so save that for the chargers.
Overall, your best bets are Thursday the 20th for the big, glassy power session (experts only), and Wednesday the 26th morning for a much more user-friendly, clean day.

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