The Lowdown
Alright, folks, Rusty here. Let’s get into it.
We’re looking at a stretch that starts off quiet and stays that way for a while. The energy just isn’t there for any proper sessions for the first week and a half or more. There’s a long gap from now until the tail end of the month where you’d be flogging a dead horse out there.
Right off the bat, Monwabisi Strand is the only break on the menu, but it’s a real slow burner. The water is sitting at 58°F, which is a bit colder than normal for this time of year.
From August 20th through the 31st, it’s pretty grim. We’ve got onshore and cross-onshore winds from the S and SW most days, keeping things choppy and messy. The odd morning might clean up, like the 22nd with a light NNW cross-off, but the swell is tiny and weak. The 27th shows some glassy conditions with light WSW wind, but again, the waves are small. The combined energy barely gets into the hundreds, well under the moderate mark, and the periods are short. There’s a little juice on the 25th with a 5ft SSW swell and 14-second period, but the cross-shore winds ruin it. Honestly, you’re better off doing something else.
Then we hit a big wall of swell. On September 2nd, we’re looking at a massive 12ft SW groundswell with a very long 15-second period and the combined energy hits a huge 5020. That’s strong, powerful stuff. The wind is offshore from the NW, so it’ll be clean, but this is way too big for anyone but the experts. The break is a sandbar and exposed, so it could be wild. Not a day for the faint-hearted.
The standout window is the morning of September 3rd. The swell drops to a more manageable 8ft SSW with a 12-second period, and you’ve got a clean NNW cross-off breeze. The energy is still a strong 2194, but it’s listed as excellent conditions for experienced surfers. That’s the one. The crowd factor is “sometimes,” so you might have company, but it’s the best the outlook has to offer.
Right after that, on September 4th, the morning looks lovely with glassy conditions and a clean 5ft SW groundswell (12-second period). That’s a solid, clean option for the more moderate crew.
To sum it up, sit tight through the last week of August – it’s a write-off. The real action is the first few days of September, with the 3rd morning being the absolute standout for those with the skill to handle it.
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.
