The Lowdown
Alright crew, Rusty here. Let’s talk about what’s in the water for the next couple of weeks. We’ve got a big ol’ gap of nothing at the start, so don't rush.
We’re looking at a flat spell that stretches from now all the way through to Friday the 20th of September. That’s about ten days of tiny, wind-chopped junk. Just leave the board in the car.
Things get a pulse on Sunday the 20th of September over at St Mikes (reef). Swell is 1.4m from the SSW with a long 20-second period – that’s proper groundswell energy (1317 combined energy). But the wind is cross-onshore and it’s choppy, so it’s a write-off. Super frustrating.
Mark your calendar for Wednesday the 23rd of September. That’s the one. St Mikes gets a solid 10ft (3.0m) south swell, coming from the S (right in the SW sweet spot). The period is 10 seconds, so there’s plenty of push (1549 combined energy). The wind is clean, cross-offshore. That’s our window. The water temp is normal for this time of year. Just a heads up: 10ft is for experienced surfers only – this is not a beginner wave. The days around it are smaller and messier.
Don’t waste your time before the 23rd. That Wednesday is the only real standout, but it’s a ways off, so keep an eye on the forecasts.
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.
