The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for St Mikes over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week and a half is a tough one. We're looking at a long, dry spell with pretty much nothing worth paddling out for. From Friday the 4th right through to the middle of the month, it's a whole lot of cross-shore wind, lumpy chop, and poor conditions. The swell is there in size, especially Monday the 7th with a 8ft S groundswell (very long period of 16s) and a massive combined energy of 2894, but it's absolutely hammered by a fresh 35 km/h NE cross-shore, turning it into a messy, bumpy mess. That's more of a kite session than a surf. The water temp is sitting at 71°, which is pretty average for this time of year.
Now, if you're patient, there's a little glimmer. On Monday the 14th of September, we get a moment of calm. The wind drops right out, going glassy, with a slight air. The swell is small, only 3ft from the S, but with that glassy surface, it's surfable. It's not going to blow your mind, but it's the cleanest we'll see in a while. The energy is weak at 218, so don't expect much push.
The real standout, the one to circle on your calendar, lands on Friday the 18th of September. That morning, the stars align. The wind is glassy again from the S at only 5 km/h, and the swell bumps up to a clean 5ft from the SSE. The combined energy is a solid 708, and the forecast is calling for very good surf conditions. This is the best on offer, no question. It's a reef break, so that long-period groundswell (11s) will wrap in nicely, and with the glassy conditions, it'll be smooth as butter. The water temp will still be around average for the time of year.
The rest of the second week, like the 16th and 17th, has size but gets messy again with cross-shore winds. The 19th looks average. So, hold out for that Friday the 18th morning session. That's the one.
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.
