The Lowdown
G’day, Rusty here. Look, I’ve had a good look at what’s coming our way for Bulli Beach over the next couple of weeks, and I’ll be straight with you – it’s a pretty bleak run for a while. We’ve got a solid stretch of flat or junk conditions from now, all the way through to late September. I’m talking nearly ten days of nothing worth paddling out for. The wind’s all over the shop, mostly cross-on or onshore, and the swell just isn’t showing up in any meaningful way. The water temp is sitting at 65°F, which is about average for this time of year, so no surprises there. But don’t get too down – it tends not to stay this poor for long, and forecasts can change.
We finally see a bit of life on Saturday the 26th of September. The morning session is the standout of the whole outlook. Bulli Beach is an advanced-level beach and reef setup, and it’s exposed to swell from the NE, which is exactly what the guidance tells us is the optimum direction. The Saturday morning offers a solid 6ft of NE swell with a period of 8 seconds, and the wind is light NNE at 9 mph, coming cross-offshore, keeping things clean. The combined energy is a moderate 365, which gives the waves a bit of push. That said, this is still a beach and reef break, and with the swell just under 6ft, it’s heading toward that territory where it gets more interesting for experienced surfers. Beginners might find it a bit much. Also, this spot can get crowded sometimes, so expect some company if you head out.
The Saturday afternoon on the 26th drops off with a light rain and the wind turning cross-shore, so the quality fades. The rest of the outlook after that is a write-off, with onshore winds and dropping swell. So, if you’re keen, make the most of that Saturday morning window – it’s the only real shot we’ve got.
Rusty.

A general guide to surfing at Bulli Beach can be found by selecting the local surf guide option on the grey menu.

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 Bulli Beach 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.
