The Lowdown
Alright folks, Rusty here with the long-range look at Monwabisi Strand in the old units.
Honestly, the next few days are a washout. Wednesday and Thursday are blown out with onshore wind—don't bother. Friday and Saturday stay cross-shore with short-period slop, barely worth a paddle. Wait until Sunday the 13th for the first real session.
Sunday morning is the clear winner. Wind goes light offshore from the NW—just a slight cross-off—and the water turns glassy clean. Swell is a solid 4 ft from the SSW with a 14-second period, real groundswell energy (1210 combined). It's got enough juice for a fun session, and at that size it's fine for most intermediates. Water temperature is 59°F, about normal for the season. The break is exposed south, and the swell direction lines up with the optimum. Crowds are possible, but Sunday morning might keep it mellow.
Sunday afternoon stays clean with a light NW cross-off, waves around 4 ft. Still a good session.
Monday the 14th brings offshore north wind, lighter in the morning at 9 mph, with 3 ft SSW swell and a 12-second period. Small but clean. Afternoon gets windier and smaller, so the morning is your window.
Tuesday the 15th has strong cross-off winds and the swell period jumps to 20 seconds—very long period groundswell—but the energy is low (351) and the wind is strong. The long period will make the waves wall up at this beach–sandbar setup; better for a point or reef. Not great here.
The middle of the second week (16th–19th) is mostly cross-onshore or strong cross-shore wind with lumpy chop. Waves get bigger but quality is poor. Not for surfing.
Toward the end, Thursday the 24th morning shows glassy conditions—light variable wind, 3 ft SW swell with a 16-second period (groundswell). Combined energy is moderate (393), and with perfect glass you could get some clean walls. It's small, but those long intervals bring shape if you find the right bank. Not a standout like Sunday the 13th, but a solid backup.
So bottom line: Sunday the 13th morning is your best shot—clean, decent size, and real energy.
Rusty.

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.
