The Lowdown
Alright, grab a cuppa and listen up. It's Rusty here, and I've been staring at the charts for Constantine Bay, and it's a bit of a mixed bag to be honest.
First off, we've got a couple of solid days of swell, but the wind is the real villain here. For the first few days, it's a write-off. Friday morning the 21st, we've got a cross-shore gale howling at 16 mph, and the sea is a mess. The water is a touch warmer than normal for this time of year at 66°, but that's small comfort.
We finally get a window of clean surf on Saturday morning the 22nd. The wind swings offshore from the ENE at a light 6 mph, and the bump is gone. The swell is small, just 2 ft coming from the west with a 10-second period. The combined energy is weak (105), so don't expect much push, but it'll be clean. Saturday afternoon stays clean but the wind picks up a touch.
Sunday morning the 23rd is glassy, with a light offshore breeze, but the swell is tiny, barely 0.7 ft. You'd be hard-pressed to get a ride. The rest of the week is a slog. The wind is either cross-shore, cross-on, or onshore, and the swell is unremarkable for the most part.
The real story is the end of the run. Wednesday the 3rd of September morning is a gem. The wind is dead calm, glassy, and the sea is flat as a pancake with a 2 ft west swell. That's your best bet for a peaceful, clean session, even if it's small. Then, later that same day, the bottom drops out. A 7 ft NNW swell rolls in, but it's accompanied by a 9 mph cross-onshore wind, making it a messy, lumpy affair. That's a lot of water moving around with a combined energy of 458, but the wind just ruins it.
The 8 ft plus swell we see on the 31st of August and 1st of September is for experts only, and with the onshore winds, it's likely a washing machine. For a beach and reef setup like Constantine Bay, the long period swell (like the 14-second one on the 23rd) might be too straight for the beach break, but the reef could offer a better shape.
Overall, the standout is that glassy morning on the 3rd of September. It's a long way off, so don't bank on it, but it's the cleanest option on the cards. The rest of the 16 days? It's a lot of waiting for the wind to play nice.
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.
