The Lowdown
Right then, let's take a look at what's on offer for Constantine Bay.
Honestly, it’s a bit of a grim outlook for the next couple of weeks. The wind is just relentless out of the west and southwest, meaning we’re stuck with cross-onshore and onshore conditions for the vast majority of the forecast. The water’s a touch warmer than usual for this time of year, sitting at about 64°, but you won’t be feeling that through the bump.
We kick off on Saturday the 12th with lumpy, poor surf. A 4ft W swell at 8 seconds, but that cross-on wind is ruining it. The combined energy is weak to moderate at best (248). It stays like this through Sunday and Monday—same story, different day.
Tuesday the 15th sees the swell bump up a bit to 5-6ft from the W and WNW, but the wind stays cross-on and the period is still short at 8 seconds. The energy is moderate (371-414), but it’s just lumpy and choppy.
Wednesday the 16th is similar with a 5ft W swell and a 10-second period. Energy is moderate (519-539), but the wind is still cross-on. It’s not going to be pretty.
Thursday the 17th is a write-off. Strong winds gusting 25 mph from the WNW making it a messy, strong cross-onshore, with a short period 7-second swell. The energy is moderate (347-425) but it’s not for paddling.
Finally, a glimmer of hope. Friday the 18th. The wind swings onshore, gentle to moderate, and we get a longer period groundswell at 12 seconds. Swell is 4-4ft from the WNW and W. The energy is moderate to strong (524). This is the only real standout in the whole run—a clean-looking window with some proper shape potential for the more experienced lot. That long period will make it a bit more drawn out at this beach and reef setup.
Saturday the 19th afternoon actually gets a clean cross-off breeze and a 5ft W swell. The energy is weak (227), but the conditions are described as good, so that morning session might be worth a look if you’re desperate.
After that, it’s mostly poor again. Sunday the 20th afternoon sees a spike to 8ft from the W, but it’s a short 8-second period with a fresh cross-onshore, so that’s too big for beginners and messy for anyone else. The energy is strong (834).
From Monday the 21st, the swell fades away slowly. We drop to 3ft, then 2ft, then the whole thing just peters out. There’s a long gap with no real swell from the 23rd of September through the 26th, with tiny, weak energy and clean conditions but no waves to speak of. By the 27th, a new but messy 6ft WNW swell shows up, but it’s back to cross-onshore wind and short period—a disappointing end to the window.
So, your best bet is Friday, the 18th of September, for that cleaner groundswell. Everything else is a battle with the wind. If it weren't for that one day, this would be a kite-surfing run for the most part.

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.
