The Lowdown
Alright, this is Rusty checkin' in from Constantine Bay. Let's have a proper look at the next couple of weeks.
Right off the bat, I gotta level with you – this is a rough run. The first week and a half is pretty much a write-off. We've got plenty of size, no doubt – there's solid swell rollin' in, but every time it shows up, the wind is just tearing it to shreds. From August 29th right through to September 4th, it's a constant battle of cross-onshore gales, lumpy conditions, and poor surf. The combined swell energy is gonna be pumping, reaching a massive 1263 on the 31st of August, but with a fresh breeze onshore, it's just a mess. That 5 to 8 ft of SW to W swell is unsurfable where we are.
We get a bit of a break from the wind on Thursday the 3rd with some onshore wind but still fresh, and that 6 to 6 ft W swell is just powerin' through, but with that much breeze, it's still a no-go. It's frustrating because the energy is there.
Then finally, on Saturday September 5th, we get a little window. The morning is still a bit iffy with cloudy skies and a light onshore breeze, but the 6 ft W swell at 9 seconds has got some decent energy behind it (557). The afternoon is the real standout, though. The wind swings light and variable from the SE – that's glassy, clean, cross-offshore magic. The swell drops a touch to 6 ft from the W at 10 seconds, but it'll be clean and lined up. The combined energy is still a solid 540. This is the one day to circle on the calendar. It won't be perfect by any stretch, but it's the closest we're gonna get to a good surf.
After that, it's back into the wind machine. September 6th through to the 13th is more of the same – gusty cross-onshore and onshore winds thrashin' the sets. The swell never really quits, but the conditions are just blown out. By the end of the run, we're down to tiny 2 ft swell and some really long-period groundswell at 15 seconds, but it's too small and messed up by a moderate cross-shore. Not worth paddling out for.
So, the honest truth? One shot, Saturday September 5th. That afternoon window with the SE wind is your best bet. Get on it if you can.

Information about the Constantine Bay Surf forecast
The above surf forecast table for Constantine Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Constantine Bay can be found by selecting the local surf guide option on the grey menu. Our Constantine Bay 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 (Constantine Bay) 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 Constantine Bay 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.
