The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The next couple of weeks are looking pretty grim for Constantine Bay, to be honest. We’ve got a real flat spell on the cards before things maybe start to stir again late in the month.
The immediate future is basically a write-off. For the first stretch, we’re looking at a lot of poor surf with bumpy, onshore winds. There is a brief pulse of energy around the 20th with some 6.9ft WNW swell (moderate energy at 702), but a strong cross-onshore wind is going to chop it all up. That’s not what we want. Then the surf just falls away into nothing, a real flat spell that runs for a few days. The water temp is about average for this time of year, so no surprises there.
Things start to look a little more interesting around the 29th, but we've got to be careful. The morning of the 29th shows some 5.2ft WSW swell (284 energy) with a clean, cross-offshore SSE breeze, which is promising. That’s our first real sign of life in over a week. But it gets messy by the afternoon as winds pick up. The following week is where things get more interesting, but it's a longer-range call. There's a proper push of energy coming in the final days of the month and into September. The 1st of September is the standout, with a solid 8.2ft west swell and strong, 1275 energy. The morning looks choppy, but the afternoon is clean in a cross-offshore wind. This is a big call, but it could be the best session in the whole window. That kind of size and power is not for everyone, and at over 8ft, it’s expert territory at a place like Constantine Bay. We’re talking proper waves here.
One last thing: the surf on offer is looking so messy at times, especially around the 20th and the 1st, that a beach and reef setup like this might honestly be more interesting for the kite crew than us paddle surfers. Keep an eye on that 1st of September, though. It's got potential.

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.
