The Lowdown
Alright, Rusty here again. Let’s look at this in feet and miles per hour.
Water temp is about 58°, which is a touch colder than what we’d normally expect for this time of year – about 3°F off, so you’ll want a good wetsuit.
The first real good window hits on Wednesday, August 26th. Morning brings a clean 5ft SE swell, short period of 8 seconds, with a light cross-offshore breeze. The combined energy is moderate (514). Wednesday afternoon gets even better: the wind goes glassy, the swell is 4ft, and the energy holds (442). That’s prime, forgiving conditions for a beginner-friendly sandbar.
The absolute standout is Friday, August 28th. Friday morning is glassy with a clean 4ft S groundswell, period stretching to 14 seconds. The energy is solid (765). That’s a long-period swell, and with zero wind, the shape will be there for some long, clean rides. Friday afternoon is another glassy session, 3ft of S swell, with good energy (538). That Friday morning is the session to plan for.
Then we have Tuesday, September 1st. Both morning and afternoon are glassy again, with a 5ft SSW groundswell (14 seconds) in the morning and a 5ft in the afternoon. The energy is strong (967 and 685). That’s a step up in size, still okay for intermediate surfers, but the power is there.
There’s a gap of poor conditions after that, then a spike on Friday, September 4th. The morning shows a 8ft SSE swell – that’s expert territory. The energy is very strong (1526). Light cross-shore wind, but at that size with a short 9-second period, it’s going to be a heavy, messy beast.
The best of the lot is Friday, August 28th. Glassy, clean, and a proper long-period swell. Don’t miss it.
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. Our Monwabisi Strand surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. 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.
