The Lowdown
Grab your board, 'cause we've got a long-range look at Constantine Bay, but honestly, it's a bit of a mixed bag with a late reward. The water's sitting at a warm 67°, which is much warmer than normal for this time of year, so you can leave the thick wetsuit at home.
The next week and a half is a bit of a grind. We've got a fair bit of swell energy kicking around, but the wind is just not playing ball. From Wednesday, August 12th, we see small 3 ft waves from the west, but the wind is cross-off or cross-shore, and the wave energy is weak (125 for the morning). It's surfable but nothing to get excited about. Thursday the 13th brings a slight bump to 4 ft with a longer 11-second period, giving moderate energy (269), but the wind swings cross and cross-on, leaving it marginal and choppy.
From Friday, August 14th right through to Wednesday, August 20th, it's a write-off. The wind is relentless, blowing fresh and either onshore or cross-onshore, with some days hitting 19-22 mph. The swell bumps up and down, with a peak of 6 ft on Thursday the 20th morning (strong energy at 387), but with that fresh cross-shore wind, it's lumpy and messy. Honestly, for a beach and reef setup, this is looking more interesting for the kite surfers than us paddle folk. There's a solid 8-day stretch of poor conditions here.
Now, here's the light at the end of the tunnel. The real standout and the only time I'd recommend paddling out is on Friday, August 21st. The morning is looking prime. We've got a clean 4 ft swell from the west with an 8-second period, a moderate combined energy of 214, and the wind is a light offshore breeze from the ESE at just 6 mph. This is the cleanest we'll see it, with that offshore wind grooming the waves. The score says "expect good surf conditions," and for once, the wind is on our side. It's a bit of a wait, but that Friday morning session is the one to circle.
After that, the weekend of the 22nd and 23rd offers small, clean waves with light offshore winds, but the swell drops to 1-2 ft and the energy is weak (40-93). It's surfable for a longboard or a learner, but not a standout. The consistency is very consistent here, so it's a shame the wind has been so cruel.

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.
