The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what Constantine Bay has on the cards over the next couple of weeks.
The truth is, it’s a bit of a slow burn to start. We’ve got a lot of poor surf conditions and onshore wind filling the first five or six days, so you won’t be missing much if you sit tight. The water temperature is sitting at 64°F, which is a touch warmer than normal for this time of year – not a bad thing if you’re getting in.
The first real glimmer comes on Tuesday the 22nd. That morning, the wind goes completely glassy with a slight air, and we’ve got a clean 4ft swell rolling in from the west with a decent 12-second period. The combined wave energy is moderate (582), and the conditions are looking very good. This is the kind of window where Constantine Bay will feel like a different spot – clean lines, no chop, just you and the ocean. That morning is the standout for the whole run.
After that, Wednesday the 23rd morning keeps the quality going. We get light offshore wind from the east, a 5ft swell from the west-northwest, and a nice long 13-second period. Energy is solid at 689, and the surf is clean again. It’s not as glassy as Tuesday, but the offshore flow will groom those waves nicely. This is your second-best bet.
The following week gets a bit messy again. There’s a huge pulse of swell on Monday the 28th with 15ft waves pumping in, but the wind is onshore and the surf conditions are poor. That’s expert-only territory, and even then, with the wind, it’s not going to be pretty. By Tuesday the 29th it’s dropped to 8ft, but the cross-on wind doesn’t do it any favours. You might find a few, but it’s a long paddle for not much reward.
All in all, the next two weeks are a story of two days: Tuesday 22nd morning for the glassiest, cleanest surf, and Wednesday 23rd morning for that offshore flow and consistent long-period waves. Everything else is either blown out, too small, or too raw.
That’s it from me. Keep your eyes on the horizon, and I’ll see you in the water.
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.
