The Lowdown
Alright folks, Rusty here, looking at what's on the cards for Amanzimtoti over the next couple of weeks. Gotta be straight with you – it's a tough forecast. We've got a long stretch of pretty average to poor conditions before any real hope shows up.
Right now, for Friday the 21st, there's some SSW groundswell coming through at around 5 ft with a decent 13-second period. The energy is moderate (880). Problem is, it's cross-shore and the wave comment is already calling it marginal. The water temp is about average for this time of year. It's not the worst, but it's not the best, either. The real bummer is the wind goes nasty on Saturday afternoon, and we're looking at a whole lot of days where the wind is either cross-on or just too strong, making a mess of things. For a spot like Amanzimtoti, a beach and reef setup, this kind of wind just isn't friendly.
There's a real gap in quality surf here. Saturday the 22nd morning sees the swell drop significantly to 3 ft, and while it's clean and light, the wave energy is weak (352). It’s just not enough to get excited about. Then we go into a long, bleak run. From Sunday the 23rd right through to Monday the 31st and beyond, most of the reports are either "poor surf conditions" or marginal at best, with scores that reflect that. The swell sticks around but the wind is just constantly onshore or cross-onshore, creating a lumpy, choppy, or messy surface. It’s one of those periods where you might as well save the gas.
Now, here's the one true standout, and it's a promise for the future. On Wednesday, the 2nd of September, we finally get a moment of clarity. The morning is still light cross-on, but the afternoon? Glassy. The wind goes completely still (ESE at 3 mph). The swell is a clean SSW groundswell at 3 ft with a very long 16-second period. The combined energy is moderate (555), and for the first time in the forecast, the conditions are flagged as "expect very good surf conditions". That long period should produce some nice, walled-up lines on the reef. This is the session to pencil in. Keep an eye on it, but it’s looking like the only real winner in the whole 16-day window.
The rest of the second week is a write-off again, with small swell and strong winds returning.
Stay patient, wait for that glassy afternoon on the 2nd, and don't bother with the rest.
Rusty.

Information about the Amanzimtoti Surf forecast
The above surf forecast table for Amanzimtoti provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Amanzimtoti can be found by selecting the local surf guide option on the grey menu. Our Amanzimtoti 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 (Amanzimtoti) 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 Amanzimtoti 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.
