The Lowdown
Alright, let’s be straight with you. St. Mike’s is the only spot on the cards for this whole stretch, and honestly, it’s looking pretty grim for a good chunk of the next couple of weeks. We’ve got a lot of small, junky surf and cross-shore breezes messing things up. But there’s a tiny glimmer of hope tucked in there, so let’s walk through it.
Right now, Tuesday morning, we’ve got a weak 0.3m (1ft) SSW swell with a 12-second period. The energy is weak (28) and it’s choppy with a cross-on breeze. Nothing to get excited about. Tuesday afternoon turns glassy but the swell drops to nothing. That’s a flat spell.
Wednesday morning is still flat. Wednesday afternoon, though, we see a quick spike – 2.2m (7ft) of SSW swell but the period drops to a junky 6 seconds. That’s short-period windslop, plus a strong cross-shore wind making it messy. The energy jumps to 478 but it’s not going to be any fun. Thursday brings a bit more size – 1.7m to 2.5m (5-8ft) – but it’s onshore and lumpy, with a period still under 10 seconds. This is all poor surf.
Then it completely dies again. Friday and Saturday are tiny, back down to 0.3m (1ft), with fresh cross-onshore winds. The water temp is sitting at 21° (70°F), which is pretty much normal for this time of year, so no surprises there.
After that, we have a few days of nothing much until Monday the 21st. That’s when things get a little interesting. Monday morning, we’ve got 1.6m (5ft) of SSW swell with a 7-second period, but it’s glassy. The energy is moderate (275), and for once the conditions look clean. It’s not big, but it’s the best we’ve seen. Monday afternoon, the swell pushes up to 2.4m (8ft) but the period stays short, and a cross-off wind keeps it clean. Still, with that short period, it’s going to be lumpy and not particularly well-shaped. This is the only real window where you might get a few, but it’s far from perfect.
And that’s it. After Monday, it’s back to small, crumbly, and cross-shore chop for the rest of the run. We see some energy pick up around the 25th and 27th, but the winds are fresh and cross, and the periods are too short. There’s nothing that’s going to get your heart racing.
So, the honest truth is – for the next 16 days, St. Mike’s is not turning on. The only faint glimmer is that Monday the 21st window, and even that is marginal. A 2.4m (8ft) short-period swell with a cross-off wind, on a reef, might give you a few workable ones if you’re keen and don’t mind the inconsistency. But for the most part, you’re looking at a whole lot of nothing. When it’s like this for so long, you just gotta wait it out – forecasts can change, but right now, it’s a waiting game.
Rusty out.

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.
