The Lowdown
Alright, let’s have a look at what’s on offer for Constantine Bay over the next couple of weeks.
To be honest, mate, it’s a pretty grim run. The whole 16-day window is looking like a write-off for any decent surf. There’s a real gap here with no good waves to speak of. The first few days are particularly rough – Wednesday the 19th through to the end of August are all marked by poor surf conditions. You’ve got a lot of strong onshore and cross-onshore winds smashing up whatever swell is there. The water temperature is sitting at 66°F which is much warmer than normal for this time of year, so at least it’s not a cold session if you do go for a paddle, but the waves themselves are just not worth it.
The only faint glimmer I can see is on Tuesday morning, the 25th of August. There’s a bit of a cleanup with a gentle breeze and a cross-offshore wind, and the wave comment says “surfable waves but very ordinary conditions.” The swell is tiny though, just 1ft from the WNW with a period of 10 seconds, and the combined energy is a weak 40. It’s not really something to get excited about, but if you’re desperate for a float, it’s the only window that’s not completely trashed. Even then, it’s hardly a standout.
The rest of the period is just bad news. Thursday the 27th sees some moderate sized swell, up to 5ft from the west, but the wind is onshore and the conditions are poor. By the end of the month, on Monday the 31st of August, we get a pulse of 8ft swell from the west with a period of 10 seconds and a massive combined energy of 1277 – that’s a strong, powerful swell. But the wind is a fresh cross-onshore, so it’ll be a lumpy, blown-out mess. That’s one for the experts only, and even then, it won’t be pretty.
Honestly, for a spot that’s usually very consistent, this is a blank run. The forecast can change, but right now, I’d say leave the boards in the van and go for a walk along the beach instead.

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.
