The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Right off the bat, I'm not gonna sugarcoat it – the start of this run is a bit of a struggle. The surf is tiny and the conditions are messy. The water temp is sitting right around 70°, which is bang on average for this time of year, so no surprises there.
We’ve got a long wait ahead. There’s a stretch of days with poor to marginal surf, so you’re looking at a gap of several days with nothing worth rushing for. The first real glimmer of hope shows up on Friday the 21st of August. We’re looking at swell from the SSW pushing 6 ft, with a solid period of 14 seconds. That’s a proper groundswell, carrying a moderate to strong energy reading (1213). The wind is cross-shore from the NE at 15 mph, which means it’ll have a bit of a chop on it, but with that size and period, Amanzimtoti should have some worthwhile waves. It’s a beach and reef setup, so the longer period should wrap in nicely.
The weekend after that, the 22nd and 23rd, gets a bit lumpy. The wind swings more cross-onshore and picks up, making things choppy. The swell sticks around, but the quality drops. Honestly, with that much wind and a beach break, it might be more interesting for the kite surfers than us.
Now, the thing that catches my eye is Monday the 24th of August. Not the morning, but the afternoon. The swell is 6 ft from the SSW, but the period jumps to 16 seconds – that’s a very long period groundswell. The energy reading is a strong 1542. The wind is a cross-shore NE at 15 mph, so not perfect, but the raw power and shape potential from that long period is a standout. This is a promising one, but it’s a way out, so keep an eye on it.
Later in the week, Wednesday the 26th of August has some serious energy with a huge 20-second period and a 6 ft swell, but the wind is a fresh 19 mph cross-shore, making it lumpy. That’s raw power (2720), but it’ll be a battle.
The very end of the run, on Monday the 31st of August, shows another big SSW groundswell – 7 ft with a 16-second period. That’s big, strong energy (2024), but again, with a fresh 22 mph cross-shore wind, it’s going to be messy and choppy. That’s a wave for the experts only, and even then, it’s going to be a tough session.
So, to wrap it up: the first half of the run is a write-off. The best bet on offer is the Monday afternoon of the 24th of August, with that long-period groundswell. The Friday the 21st is your next best shout. Just manage your expectations for 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.
Amanzimtoti is 9 km (6 miles) from Umlazi. If you plan a holiday in Durban/KwaZulu-Natal South Coast, look for hotels and other accommodation in Umlazi. Umlazi has rooms for a wide range of budgets as well as car hire and transport links.
