The Lowdown
Alright, Rusty here. Let’s break down St Mikes for the next couple weeks.
First thing’s first: it’s a rough start. A long stretch of nothing from Sunday the 13th through Wednesday the 16th. The waves are tiny and the wind is all wrong—cross, cross-on, and gusty. That NE wind on the 13th is blowing 30 km/h cross-on, messing up the 0.7m SSW swell. The water’s at 21°, about average for this time of year, but you won’t care because the surf is garbage.
The first real chance comes Thursday morning the 17th. A 1.6m SSW swell with a gentle 15 km/h WSW cross-off wind and clean conditions. Combined energy is moderate at 207. It’s called “surfable but very ordinary,” so it’s nothing special, but it’s the best we’ve seen. The afternoon turns heavy rain and onshore wind, wrecking the 2.4m S swell.
The real standout is Saturday morning the 19th. Wind goes glass—dead calm, 5 km/h from the SSE. Swell is a clean 1.6m from the SE with a 6-foot period. Combined energy is moderate at 356. The conditions are glassy, and it’s a reef setup that will hold that swell. This is the best on offer. Expect company though—crowds are often here.
After that, Sunday the 20th flattens out again with just 0.3m swell.
The week from Monday the 21st to the 27th is a write-off. Strong winds, cross or onshore, small messy waves, chop, and lumpy conditions. Nothing worth paddling for.
The long-range look is Monday morning the 28th. Combined energy jumps to 1608—that’s strong. A 2.1m SE swell with a 10-second period and a clean 25 km/h cross-off wind from the SW. That’s big and powerful, expert-only stuff. The forecast is marginal due to tide, but if it lines up, it could be a bomb. That afternoon goes back to cross and messy.
So, bottom line: Saturday morning the 19th is your day—glassy, fun waves. Keep a loose eye on Monday the 28th morning for the big boys. Otherwise, the board stays in the car.
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.
