The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Monwabisi Strand over the next couple weeks.
Water temp is running 57° – that’s a bit colder than usual for this time of year, so you’ll want a thicker suit. There’s swell coming, but the wind is going to be the main headache. We’ve got a lot of onshore and cross-onshore wind, and the tide conditions are keeping things marginal.
Monday starts with a 5ft SW swell, 13-second period, with the wind from the NNW at 12 mph, cross-off. It’s clean, but not much juice. By afternoon, wind drops to 6 mph from the west, light cross-on, and the swell backs off to 4ft. Small and a little bumpy. Tuesday bumps up to 6ft to 6ft, SW and SSW, but the wind is cross-on from the south at 9 to 12 mph, making it choppy. The combined energy Tuesday morning is big at 1691, but the wind kills it. From Monday through Friday, it’s a write-off for quality.
Wednesday 26 August morning is the one to mark. Swell sits at 5ft from the SW, 12-second period, and the wind goes light cross-off from the northwest at just 3 mph. Clean conditions, combined energy at 579 – not huge, but it’ll be the cleanest wave of the week. That’s your window.
After that, the following week drops off. Thursday 27 August starts with a tiny 3ft swell, and the wind stays onshore or cross-onshore from the south. By Sunday 30 August, the swell jumps to 7ft to 8ft from the SSW, but again the wind is onshore. Combined energy hits 1960, so there’s power, but it will be a battle. That’s expert territory only in those conditions.
Looking into Tuesday 1 September, we’ve got a glassy morning with a light southwesterly breeze at 3 mph. Swell is 5ft from the SSW at 12 seconds, combined energy at 785. That’s your second standout – clean, smooth, and manageable. Not huge, but glassy conditions make it the best ride of the whole stretch.
So, to sum it up: the clear standouts are Wednesday 26 August morning and Tuesday 1 September morning. Everything else is wind-battered or just too small. Pounce on those windows.
Rusty.

A general guide to surfing at Monwabisi Strand can be found by selecting the local surf guide option on the grey menu.

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.
