The Lowdown
G'day, Rusty here. Let's have a proper look at what's on the table for St Mikes over the next couple of weeks. I gotta be straight with you – the start of the run is a tough one. There's a whole lot of nothing for the first several days, with nothing worth paddling out for until we hit the middle of the month.
Right from Saturday the 12th, it's a write-off. We've got a measly 3ft swell from the south, but that's being blown to bits by a 16 mph cross-onshore wind. The water's sitting at 69°, which is about average for the time of year, but it's not gonna make up for the messy, choppy surface.
It stays poor right through until the afternoon of Thursday the 17th. That Friday morning the 18th, we finally get a bit of hope. The swell picks up to 8ft from the SSE, with a clean cross-offshore breeze (3 mph WSW). The combined energy is strong at 973, and the period is a workable 10 seconds. This is the standout morning of the first week – clean, punchy waves for the advanced crew. It's a reef break, so expect some proper line-ups, but the crowds are often here, so get in early.
Then, looking ahead to Monday the 21st, we've got a real beauty on the cards. The morning is looking glassy – dead calm with a 3 mph westerly offshore breeze – and a solid 10ft swell from the southeast. The combined energy is cranking at 1405. That's serious power, and with a 9-second period it'll be a bit raw and chunky, but for the experienced surfer, it's a goldmine. This is your day if you've got the skills; it'll be too much for beginners.
Beyond that, the second week gets messy again. There's a bit of a pulse around the 24th with 7ft from the south, but the winds are all wrong – cross-shore or onshore. The 26th has a big 8ft south swell with 16-second period (groundswell), but a strong cross-shore wind makes it a lumpy, chaotic mess. The 27th is another stale day.
The standout sessions are definitely the morning of Friday the 18th and the glassy morning of Monday the 21st. That Monday looks like the pick of the entire run – big, clean, and powerful. If you're local and you're ready, that's the one to circle on the calendar.
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.
