The Lowdown
Right then, let’s take a look at Constantine Bay. It’s a beach and reef setup that’s very consistent and exposed to the west, and it takes a bit of a battering this period.
The water temp feels pretty average for the time of year, nothing unusual to report there.
To be brutally honest, the first ten days or so are a write-off. We’ve got surf, sure, but the wind is all over the shop – mostly cross-onshore or howling onshore, which means chop and lumpy conditions. It’s not the kind of thing you paddle out for unless you’re desperate for a beating. The energy hangs around moderate to strong, but the quality is just poor. There’s a bit of a gap where nothing is really recommendable until the weekend after next.
Now, the 19th of September (Saturday) afternoon is where it gets interesting. The wind drops to glassy, and we’ve got a solid 7ft of west swell coming in. The energy is moderate, and the guidance says expect very good surf conditions. That’s the first real standout – clean, punchy, and all for you if you can get out there. It’s a bit on the bigger side for beginners, but intermediates will love it.
Then, looking further out to the 23rd (Wednesday) morning, it goes glassy again. A clean 7ft west swell with no wind at all makes for a gorgeous session. The energy is moderate, but the glassy conditions will make it a real treat.
But the absolute pick of the lot, the one to circle on the calendar, is the 25th of September (Friday) morning. This is a standout. You’ve got 10ft of west swell, with glassy conditions and an ENE breeze that’s just a whisper. The wave energy is strong, and the guidance calls it excellent for experienced surfers. This is proper, powerful groundswell, and with that period around 9 seconds, it’s got plenty of push. It’s going to be a big, clean day – only for those with skill and a bit of nerve. The Saturday morning after that also looks cracking, with strong energy and clean cross-off winds.
So, bottom line: you wait, you wait, then you get a couple of glassy gems, and one absolute belter of a day for the crew who can handle it.
Rusty.

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.
