The Lowdown
Alright folks, it’s Rusty here with the skinny on Monwabisi Strand.
We’re looking at a pretty mixed bag over the next couple of weeks. The water’s sitting at 57°, which is a touch colder than usual for this time of year – you’ll feel that bite.
The week kicks off with some size but messy conditions. Tuesday afternoon is a write-off with a 6ft SW swell, but that 12 mph cross-onshore South wind is just going to chop it all up. The energy is strong though, coming in at (1150). Wednesday and Thursday aren't much better, with onshore winds and marginal conditions. Things start to look up on Friday afternoon, the 21st of August. The swell drops to a clean 5ft from the SSW with a period of 11 seconds, and the wind goes glassy. That’s your first real chance for a proper session, with moderate energy (812). It won't be huge, but it'll be clean and fun.
The weekend is a bit of a dud. Saturday morning has some clean-ish cross-offshore wind but the swell is tiny at 3ft. The rest of the weekend and early next week are plagued by onshore winds and dropping swell, with very low energy readings. We have a long gap with no real standouts here.
Now, look ahead to the final day of the month, the 31st of August. Monday morning is where the magic might happen. We’ve got a solid 6ft SSW groundswell rolling in with a very long period of 16 seconds. The wind is light and offshore from the NNE at 6 mph. The combined energy is strong at (1782), and the call is for excellent conditions for experienced surfers. This is the standout of the whole forecast. That period is so long that the waves will have serious power and shape, perfect for a spot like this. It's a bit of a wait, but if it comes together, it'll be worth it.
Beyond that, early September looks poor again with choppy conditions and fading swell.
So, to wrap it up: don't bother with this week. Friday afternoon the 21st is your best bet for a clean, smaller session. The one to circle on the calendar is Monday morning the 31st of August for the biggest, cleanest, and most powerful swell of the whole run.
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.
