The Lowdown
Alright, Rusty here again. Let’s break it down for the imperial crew. The outlook for St Mikes is a long, frustrating wait, with just one short window that looks half-decent. The standout is next Wednesday, the 26th of August.
We start off with a bang on Sunday the 23rd, but it’s a bad bang. There’s a solid 10ft swell from the SSW, with a massive combined energy of 2838 (strong to very strong). But the wind is a howling cross-shore from the SSW at 15 mph, and the surface is a cross-chop. It’s just not surfable. By Sunday afternoon, the swell drops to 5ft, but the wind shifts to a S cross-shore at 12 mph, and it’s still poor.
Monday the 24th and Tuesday the 25th are a total washout. The swell drops to 3ft, and the wind is all over the place. This is a waiting game.
Wednesday morning the 26th of August is the one. The swell is 5ft from the S, with a very long period of 17 seconds. That’s a proper groundswell with a moderate to strong energy (1359). The wind is a light cross-shore from the south at only 3 mph, which will keep it glassy. This is the best-looking window in the entire 16-day run. The caveat is that 17-second period is very long. At a reef like St Mikes, that’s usually a good thing – it’ll wrap in and have real power. But it also means longer waits between sets. The afternoon is a problem: the wind swings onshore from the east at 9 mph, and the swell jumps to 7ft. That’s expert-only territory, and the wind will junk it up.
Thursday the 27th is a mess. A strong breeze from the NE at 25 mph with a cross-shore will create a total chop. Friday through the end of the first week stays windy, with the swell struggling to hold any shape. The water temp is about average for the time of year, so no worries there.
The second week is a sad story. Tuesday the 1st of September is tiny, with 2ft swell and a fresh breeze. Wednesday the 2nd has a 3ft SSW swell with a long period of 14 seconds, but the energy is weak (324) and the wind is a problem. The furthest we look, on Thursday the 3rd of September, has a 3ft SSW swell with a 16-second period, but it’s a cross-onshore. The only real hope is that Wednesday morning the 26th. That’s your window.
If you’re an expert, the 7ft on Wednesday afternoon will be a heavy, powerful wave, but it’s onshore, so it’ll be a battle. For the rest of the 16 days, the board is staying in the car more than it’s in the water.
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.
