The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Monwabisi Strand.
Honestly, the next couple of weeks are a bit of a grind. There’s a long stretch of messy, wind-affected surf to get through before we see anything worth paddling out for. Wind is mostly out of the SE and ESE, which puts it cross or cross-onshore here, and that keeps things choppy and lumpy with some poor conditions. The first real hope isn’t until Tuesday the 22nd of September morning, when a light cross-offshore breeze from the NW cleans things right up. Swell is tiny though, only 2ft from the SW with a period around 11 seconds. Combined energy is weak at 141, so it’s small and weak but clean.
There’s another window on the morning of Thursday the 24th of September. Swell picks up but it’s messy – 6ft from the SSE with a short period of 8 seconds, cross-shore wind, and combined energy jumping to 1113 (moderate). It’s a bit of a beast for a beach break, short period slop, better left for more experienced surfers. The afternoon of that day looks better with swell dropping a touch to 6ft from the SSW, period lengthening to 13 seconds, and the wind backing off to a gentle breeze. Combined energy is 1515 (moderate) – still got some push but cleaner.
The standout for the whole outlook is Tuesday the 29th of September morning. Clear skies, light cross-offshore from the NW, and the swell is 3ft from the SSE with a 12-second period. Combined energy is low at 228, but the wind is clean and the conditions are described as “expect good surf conditions”. For a beginner-friendly sandbar break that’s fairly consistent, this is the pick of the bunch. The optimum swell direction from the guidance is S, and the swell here is SSE – close enough. Water temperature anomaly is about average for the time of year.
Later that same afternoon the wind goes offshore from the NNE at 12 mph, but the swell drops to just 1ft. Too small to get excited about.
There’s a small glassy possibility on the morning of Thursday the 1st of October – 1ft with a very long 16-second period from the SW, light wind, glassy water. Combined energy is very weak at 85. That’s a knee-high cruise at best.
So overall, if you’re hunting for something clean, aim for the morning of the 29th of September. The rest is mostly a write-off or for the patient ones.
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.
