The Lowdown
Alright, let me break this down real simple for ya.
To be straight with you, the outlook for St Mikes over this whole 16-day stretch is pretty grim. It’s one of those flat spells where you’d be better off waxing your board just for the smell of it.
We’re looking at Saturday, the 15th of August, right through to Sunday, the 30th of August, and there’s not a single standout session here. The first few days are a write-off: tiny little slop with waves barely pushing 3 ft, and with a short-period, weak windswell coming from the NNE, the energy is pathetic (50). The water temp is 70°, which is pretty normal for the time of year, so the ocean feels familiar, but it's flat. All day Saturday and into Sunday, it's just cross-shore winds messing up what little bump there is.
The swell tries to pick up around Thursday the 20th of August, seeing some 6 ft waves from the SSW with moderate energy (173), but it’s still crossed-up wind and the period is short (6-7 seconds), meaning lumpy, weak waves. That energy builds into Friday the 21st (834), but the swell period gets really long (15-16 seconds), which on a reef setup like St Mikes can be a bit gutless and straight—especially with a fresh cross-shore wind chopping it up. The conditions are poor across the board with zero clean windows.
Then Saturday the 22nd of August throws up 10 ft from the SSW, with strong energy (1098), but this is way too big for the average surfer, and with the wind still cross, it would be a messy, washing-machine kind of day. Kite surfers might have a field day in that, but for a paddle surfer, it's a no-go.
The only time the score even sneaks up to a 1 out of 10 is on Monday the 24th of August, with 6 ft of long-period S swell and very strong energy (1841), but again, the wind is cross and it’s described as marginal. The waves might have some push, but they’ll be hard to read and choppy.
After that, the swell fades again from Tuesday the 25th into the end of the month, dropping back to 2 ft or less. The last few days of August have tiny waves, weak energy, and still messy wind conditions. By Saturday the 30th, it’s a light cross-shore with a weak 2 ft SSW groundswell.
There’s just no good day in this run. The whole period is a blank for quality surf. We’ve got energy coming, but the conditions refuse to line up. Don’t lose hope completely—forecasts can change, but right now, leave the board in the garage.

Information about the St Mikes Surf forecast
The above surf forecast table for St Mikes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at St Mikes can be found by selecting the local surf guide option on the grey menu. Our St Mikes 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 (St Mikes) 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 St Mikes 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.
St Mikes is 17 km (11 miles) from Port Shepstone. If you plan a holiday in Durban/KwaZulu-Natal South Coast, look for hotels and other accommodation in Port Shepstone. Port Shepstone has rooms for a wide range of budgets as well as car hire and transport links.
