The Lowdown

Alright, this is Rusty checking in, and I gotta be straight with you—what we’ve got on the table for the next couple of weeks is a real mixed bag, and you’ll need to pick your moments carefully.

The only spot in the game is St Mikes, a reef break that’s fairly exposed and handles a SW swell best. The water temp is sitting right around 70°, which is basically normal for this time of year, so no surprises there.

For the first few days, from Tuesday the 18th right through the rest of that week, it’s pretty grim. We’re looking at weak, short-period slop, cross-shore winds, and the combined energy is barely registering (46). It’s just not worth paddling out. There’s a long gap of poor conditions until we finally see something surfable on Saturday the 22nd in the morning. That’s a tiny window with a light WSW breeze and a clean look, but it’s only 2 ft and honestly, it’s ordinary.

The real standout, the one you want to circle, is Monday the 24th in the afternoon. That’s glassy conditions, a clean 3 ft swell from the south with a very long period of 15 seconds, pumping in a solid moderate energy (462). That long period means better shaped waves and more push, especially on a reef setup like this. It’s the best call of the whole forecast.

After that, things get messy again. There’s a lot of wind and chop, and the swell jumps up to 6 ft and even 8 ft on Saturday the 22nd afternoon, but with short period and strong cross-shore winds, it’s just a washing machine. The later part of the month, from the 27th into September, has some bigger energy on the charts (like 1119 on the 28th), but the wind is always cross or cross-on, and the conditions are either marginal or poor. It’s just not clean.

For experts, the bigger, more powerful swells late in the month could be interesting, but the wind never really aligns. The 5 ft to 6 ft stuff on the 27th and 28th is too messy for a good session. The 8 ft on the 22nd afternoon is only for the brave, and even then, it’s a mess.

If you’re a beginner, stay away from anything over 5 ft, and that’s most of the second week. The 3 ft glassy window on the 24th is your best bet.

So, to sum it up: the first week is a write-off. The only real highlight is Monday afternoon, the 24th. After that, it’s a gamble with wind and chop. The second week has some powerful energy, but it’s more for the dedicated crew who don’t mind a battle.

Rusty.

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.
