The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s cookin’ for our local stretch.
The next 16 days are a mixed bag for Monwabisi Strand. We’ve got a bit of a slow start, but there’s a promising window building towards the end of the first week and into the second, with a few sessions that could be really worth paddling out for. The water is sitting at 57°, which is a bit colder than usual for this time of year – so a good 4/3 might be your best mate.
The first few days are pretty average. Wednesday morning the 19th has some 6 ft swell from the SSW but with a 12 mph onshore wind, it’s just messy. Combined energy is moderate at 893. Thursday morning the 20th sees a bigger 8 ft SSW swell, but again it’s cross-onshore, so it’s a bit of a battle. The energy picks up to 1807, but it’s not clean. Friday the 21st is small and marginal, and Saturday the 22nd has a brief window of cleaner conditions in the morning with a light NNW cross-off breeze and a 4 ft SSW swell, but the size is small. The energy is weak at 495.
Sunday the 23rd and Monday the 24th are largely onshore and poor. Not much to write home about.
Now, here’s where it gets interesting. Tuesday the 25th afternoon is a real standout. We’ve got light winds turning glassy, a 4 ft swell from the SW with a nice long 14-second period, and combined energy of 721. This is a proper groundswell – but that long period means it might be a bit straight at this beach break, so keep your eyes open. Still, glassy conditions are rare gold.
Wednesday the 26th morning is the pick of the week. A 5 ft swell from the SSW, 13-second period, clean cross-off wind from the NNW, and combined energy of 1159. This is excellent for experienced surfers. The swell direction is a solid match for the optimum S direction, and the energy is solid. This is the one to circle.
Thursday the 27th offers glassy conditions again with a smaller 3 ft S swell, good for a fun session on the longboard. Energy is moderate at 425.
The weekend of the 29th and 30th sees a big spike in swell, with 10 ft to 12 ft SSW swells, but the wind is howling from the ESE at 19 mph, creating lumpy cross-chop. The energy is huge – 2580 and 5383 – but it’s just too big and messy for paddle surfing here. This setup looks more interesting for kite surfing than a traditional surf.
After that, Monday the 31st morning is a real gem. A clean offshore breeze from the N at 12 mph, a 4 ft SW swell with 14-second period, and combined energy of 1008. Excellent for experienced surfers again. Tuesday the 1st of September morning is also glassy with a 4 ft SW swell, very clean.
The final standout is Thursday the 3rd of September morning. Absolutely glassy, zero wind, a 4 ft WSW swell with a 14-second period, and combined energy of 684. This is a perfect morning for a glassy session.
So, overall, you’ve got to wait out the early onshore slop, but the 26th morning, the 31st morning, and the 3rd morning are the true standouts. Get on them.
Rusty.

Information about the Monwabisi Strand Surf forecast
The above surf forecast table for Monwabisi Strand provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Monwabisi Strand can be found by selecting the local surf guide option on the grey menu. Our Monwabisi Strand 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 (Monwabisi Strand) 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 Monwabisi Strand 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.
Monwabisi Strand is 17 km (11 miles) from the city of Stellenbosch. If you plan a holiday in Cape Town, look for hotels and other accommodation in Stellenbosch. Stellenbosch has rooms for a wide range of budgets as well as car hire and transport links.
