The Lowdown
Alright, Rusty here. Let’s break it down.
First up, Monwabisi Strand. The water is about 60°, which is pretty normal for this time of year, nothing wild going on temperature-wise.
Friday afternoon the 11th of September kicks things off with a sloppy 7ft swell from the SSE, but the period is a short 7 seconds. The wind is cross-shore at 16 mph, and the wave energy is moderate at 612. Honestly, with that short period and choppy wind, it’s more of a kite-surfing kind of day.
Saturday the 12th looks a bit better in the afternoon. Swell drops to 6ft from the SSW, but the period goes to a very long 17 seconds. The wind goes cross-off at 19 mph, and the wave energy jumps to 1969 – that's strong. The surf is still marginal, but the long period will make for better shaped waves if you can find a bank.
Sunday the 13th is small, 5ft in the morning, and then it fades.
From Monday the 14th through to Friday the 18th, it’s pretty bleak. Winds are mostly cross-off or cross-shore, but the swell is weak or the conditions are poor. There’s a lot of days with energy down below 300. Not much to chase.
The real standout is Saturday morning the 19th of September. Glassy – no wind at all – with a clean 5ft swell from the SSW, and a 13 second period. The energy is a solid 763. The forecast calls for very good conditions. With that wind and a decent swell, the waves will be clean and lined up. Crowds can be a factor here sometimes, so get down early.
Another good call is Monday morning the 21st of September. Glassy again, just a light 3 mph breeze from the WSW. The swell is smaller at 4ft, but the period is a very long 15 seconds, and the energy is 519. Another “very good surf conditions” call. That long period at a sandbar can make it a bit straight, but with the glass, it’ll be the pick of the second week.
After that, it’s small and mostly onshore. The 26th has a tiny 3ft glassy morning, but it’s nothing to write home about.
Best on offer: Saturday the 19th morning with 5ft SSW, 13 seconds, and glassy. Runner-up is Monday the 21st morning with 4ft SW, 15 seconds, also glassy. Don’t sleep on it.
Rusty.

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.
