The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Monwabisi Strand.
The outlook starts pretty bleak, with a lot of wind messing things up for the first week and a half. But there’s a glimmer later on, though it comes with some size.
We’re looking at Monwabisi Strand (South Africa), a beginner-friendly sandbar that’s fairly consistent when conditions line up. This morning, Sunday the 13th, is actually the best it gets for a while. We’ve got a 5ft SSW groundswell rolling in with a 14-second period – that’s proper long-period energy, so it’ll be groomed nicely by the glassy conditions. The combined energy is pumping at 1490 (moderate to strong), and with zero wind, it’s clean as a whistle. This is the standout session if you’ve got an experienced head on you, though it might be a bit much for the absolute beginners at that size. The water temp is about average for this time of year, so no need for a thick suit.
That Sunday morning window is it for a while. From Sunday afternoon right through to Monday the 21st, it’s a write-off. We’ve got strong cross-off, cross, and cross-onshore winds – consistently in the 15 to 22 mph range – that smash up any potential. The swell sticks around, but the quality is zero. You’re looking at over a week of poor to marginal conditions. Even though there’s a lot of energy in the water (check out Wednesday the 16th morning with 1629 energy), the wind just ruins it.
Things start to look a bit more hopeful on Tuesday the 22nd. Monday the 21st is still a no-go, but Tuesday morning brings a shift. There’s a 5ft SSW groundswell (15-second period) with a gentle cross-off breeze and clean conditions. The energy is high at 845 (moderate). That’s a solid session for anyone looking to get a wave after the long dry spell.
Then it gets interesting and a bit wild. Wednesday the 23rd afternoon sees a jump to 8ft SSW swell with a 13-second period. The energy is massive at 2895 (very strong), but the wind turns strong cross-onshore, making it a messy, choppy beast. That’s expert territory only, and even then, the wind will make it a battle. The next morning, Thursday the 24th, has a 4ft SSW groundswell with a very long 17-second period, and energy at 1898 (strong), but it’s again cross-onshore and choppy. Then Thursday afternoon – 8ft S swell, but with a short 9-second period and fresh cross-onshore wind. That combo is just ugly and lumpy, more for kites than paddles.
Friday the 25th morning is the last real hope. A 6ft SSW swell (14 seconds) with moderate cross-shore wind, giving a cleaner look than the days before. Energy is at 1622 (strong). It’s still got some chop, but it’s worth a look for experienced surfers.
So, to sum it up: your only real standout is Sunday morning, September 13th. That’s the glassy, clean one. After that, mark your calendar for Tuesday the 22nd morning for a decent pulse with clean conditions. The rest is a battle with the wind or too big and messy.
Stay patient, and keep an eye on the charts. Forecasts can always shift.

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.
