The Lowdown
Alright folks, Rusty here, and we’re taking a long look at Bagasse. It’s a reef setup that points north, and the optimum swell direction is from the north. The problem is, this whole 16-day stretch is dominated by easterly and east-northeast swells, so it’s not really lining up with what this place wants.
We’re starting on Thursday the 13th of August, and honestly, it’s pretty grim. The swell is coming in at 6 ft from the ENE with a short, weak 8-second period. The wind is a fresh cross-offshore breeze at 22 mph, but the wave energy is only moderate (393). The conditions are described as poor, so it’s not worth paddling out. This rubbish continues through Friday and into Saturday the 15th, with the wind staying strong and onshore, mixing things up into a messy cross-chop. The swell pushes up to 8 ft and then 10 ft, and the energy briefly jumps way up into the strong range, but the wind is ruining it. That 10 ft surf on Saturday afternoon is too big for beginners anyway, and with the wind, it’s strictly for the experienced crew.
Sunday the 16th and Monday the 17th calm down a bit, with the swell dropping back under 7 ft, but the wind is still a problem. The waves are just messy and there’s no drive. We go through a big dead patch from Tuesday the 18th all the way through to Saturday the 22nd of August, where the waves are mostly under 4 ft and the energy is weak (values as low as 101). It’s just flat and ordinary.
There’s a little flicker of hope on Thursday the 20th. We get a light offshore breeze from the SSE at 6 mph, which should clean things up. The swell is only 4 ft and a weak 8-second period, but with that glassy wind, you might find a grovelly one. By Thursday the 27th, we’re back to the same old story: small ENE swell with onshore winds. The very end of the run, on Friday the 28th, is also a write-off.
So, the standout? Honestly, there isn’t one. The whole 16-day window is a washout for Bagasse. The swell direction is wrong, and when there is a tiny bit of size, the wind is on it. That Thursday the 20th morning with the 4 ft and light offshore wind is the only window that looks *possible* for a wave, but it’s still a long shot. The water temp is 84°F, which is about normal for this time of year. Don’t hold your breath on this one.
Stay salty,
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.
