The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming down the line for our stretch of coast.
We’ve got a bit of a slow start, but once the swell fills in properly, there are some absolute gems on the horizon. The opening days are okay, but the real standout action is tucked away in the second week, so keep your eye on the calendar.
Right off the bat, Thursday morning the 13th has some serious juice. Monwabisi Strand is seeing a solid 5ft SW swell with a long 18-second period, pumping a strong 1414 units of energy. The wind is a clean offshore from the NNE at 6 mph, so the lineup will be clean. This is one for the experienced crew, though; that size and period will throw some power. The water temp is about average for this time of year, so no surprises there.
That afternoon the swell drops a touch to 4ft, but it’s still very good. The wind shifts to a cross-offshore from the NW, keeping things clean enough.
Friday the 14th sees the swell backing off to 3ft, but that long 15-second period keeps the waves shapely. The morning offshore wind from the N at 16 mph will groom it nicely, but it’s more of a fun-sized day for a longboard or a fish.
Saturday the 15th and Sunday the 16th are marginal. The swell hangs around 3ft, but the wind goes a bit funky with light cross-onshore breezes and some chop. Not a write-off, but nothing to get excited about.
Then Monday the 17th morning looks real good. A 5ft SW swell at 13 seconds, 632 units of energy, and glassy conditions with a light SW wind at 3 mph. That’s clean, fun, and punchy. Tuesday the 18th morning keeps the good vibes going with 4ft and a cross-offshore wind from the NNW.
Now, here’s where it gets interesting. There’s a rough patch from Wednesday the 19th through to Wednesday the 26th. The wind turns onshore and the swell gets messy. A lot of those days are blown out or just small and weak. We’re talking a solid week of poor to marginal conditions with cross-onshore winds and choppy water. It’s a real dry spell, so don’t bother paddling out unless you’re desperate.
But hold on to your board shorts, because Thursday the 27th is the standout. Thursday morning serves up a 4ft SW groundswell with a very long 17-second period, 756 units of energy, and a cross-offshore wind from the NW at 6 mph. Clean, long lines. Then Thursday afternoon is even better: 5ft SW swell, 16-second period, 1085 units of energy, and glassy conditions with a light S wind. That’s an excellent call for experienced surfers – proper, powerful, clean waves.
And the run continues into Friday the 28th morning: 5ft SW swell at 16 seconds, 1124 units of energy, and glassy. Another cracker. This late August run is the real deal.
So, to boil it down: the first week has some fun sessions, especially Thursday the 13th morning and Monday the 17th morning. The second week is a write-off from Wednesday the 19th until Wednesday the 26th. But the absolute best on offer is Thursday the 27th afternoon and Friday the 28th morning – both are glassy, powerful, and clean. Mark those dates.
Keep an eye on the sky and don't sleep on that late swell.
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.

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.
