The Lowdown
Alright, listen up, it’s Rusty. Let’s cut to it for Constantine Bay: it’s a quiet start and a long wait for anything worthwhile.
The first few days are a no-go. On Tuesday the 8th, we had a solid 7ft west/northwest swell, but that fresh 35 km/h NNW wind just punched it up into a mess. Combined wave energy was moderate at 705, but no good for surfing.
The first real chance comes on Sunday morning, 13th September. A 5ft west swell with a 10-second period, and the wind turns light offshore from the WSW at just 10 km/h. That’s your moment. Combined energy sits at 422. Water temp is 65°, which is a tad warmer than usual for September. Constantine Bay is a beach-and-reef setup, very consistent, and it’s wide open to that west swell – the direction is spot on. With 5ft and a longer period, it’ll be best on the reef sections; the beach might be a bit straight. It gets crowded sometimes, but a Sunday morning with that wait might keep enough folks away.
After that, it’s a slow slide. A few marginal days with light cross-onshore winds and small 3ft to 4ft swell, but nothing to get excited about. Then, on the morning of Thursday 17th September, there’s a glassy 2ft west swell – combined energy is a weak 92 – clean, but tiny.
The long-range on Monday 23rd September shows a 3ft west-northwest groundswell with a very long 15-second period. The wind is a light cross-offshore NNE breeze at 25 km/h, and combined energy jumps to 456. That’s a powerful, clean swell, but with that period, it’ll be a close-out on the beach. The data calls it poor surf conditions, so don’t bet the farm on it.
The standout is clear: Sunday morning, 13th September. Clean, offshore, moderate swell. That’s your best bet. Everything else is either too windy, too small, or too far away.
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.
