The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the outlook for Bagasse.
Right off the bat, I’ll be straight with you: this isn't the kind of run that gets you frothing. The setup at Bagasse is a reef break that’s fairly consistent and exposed to the north, but we’ve got wind and swell direction fighting each other most of the time. The water temp is about average for this time of year, so no surprises there.
The first real shot at a wave comes Wednesday morning, September 9th. We’re looking at a 6ft swell out of the ENE with a short 8 second period, and combined energy hitting 579 (moderate). The wind is a cross-off from the east at 19 mph, so it’s clean but the wave quality is only marginal. Tide might mess with it. Not a standout.
Things go downhill quick. From Thursday the 10th right through to Tuesday the 15th of September, it’s a dry spell. Swell hangs around 4ft to 6ft, but the wind stays cross-off or cross, and the scores are all zeros. Poor conditions, period under 8 seconds, just no juice. Not worth paddling out.
Then, on Wednesday, September 16th, we get a pulse. The morning shows 8ft swell from the east, period still short at 8 seconds, but energy jumps up to 760 (moderate to strong). That’s a bit of size. For a reef break, 8ft is pushing into expert-only territory. Wind is cross-off at 19 mph from the east, so it’ll be clean on the face. This is the one day that might get your heart going, but that short period means it could be a bit crumbly. The afternoon drops to 7ft, still clean, still decent energy at 662. If you’re experienced, this Wednesday is your best window.
After that, it fades again. Thursday the 17th drops to 5ft, poor conditions, and then through the end of the run into the 24th, it’s mostly 3ft to 5ft, short period, cross-off winds, and zero scores. There’s a little bump on Tuesday the 22nd with 5ft and 270 energy, but it’s still just poor.
Overall, the only real standout is Wednesday, September 16th with that 8ft swell. Everything else is a waiting game. For a reef break like Bagasse, it’s not unusual to have these flat, windy stretches.
Rusty.

Information about the Bagasse Surf forecast
The above surf forecast table for Bagasse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bagasse can be found by selecting the local surf guide option on the grey menu. Our Bagasse 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 (Bagasse) 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 Bagasse 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.
