The Lowdown
Alright, Rusty here. Let’s talk about Bulli Beach.
To be honest, mate, it’s a grim start. The first week is a write-off, with tiny, weak waves and messy wind. You’re looking at a solid six days of frustration before anything even hints at a pulse. The best of the whole run is a couple of standout windows, but you’ve got to be patient.
The first real glimmer comes on the morning of the 29th of August. That’s the pick of the first half. We’ve got a 4ft NE swell, and the wind is offshore from the NW, blowing clean at 9 mph. Combined energy is solid (262), and it’s the only proper clean session in that week. The swell period is a short 8 seconds, so it’s not gonna be a groundswell classic, but it’ll be surfable, and the crowd might be there at Bulli Beach (break in the Illawarra region) since it’s a fairly consistent spot that can get busy.
Then we get a few days of mid-range, forgettable slop before the real standout. The morning of the 3rd of September. That’s the one to circle. The swell is 5ft from the NE, the wind is a clean offshore from the north at 9 mph, and the combined energy jumps to 277 (moderate). The period is still short at 7 seconds, but the conditions will be clean. Later that afternoon the swell bumps up to 6ft from the NE, with a moderate 16 mph cross-off breeze, and the energy rockets to 604 (strong). That’s proper juice. For a break like Bulli Beach, which is a beach and reef setup, that 6ft is getting into expert territory, and the short period means it’ll be a bit walled up, but the clean wind will make it the best session of the whole 16 days.
The water temp is 65° F, which is normal for this time of year, so no worries there.
The rest of the second week is a mix of clean but tiny days, or bigger swell with onshore wind. The morning of the 5th of September is glassy with a 2ft E swell at a longer 10 seconds, but it’s tiny, so only worth it for a longboard.
So, to sum it up: wait for the morning of the 29th of August for a decent session, but the true standout is the morning of the 3rd of September. That’s your best bet.
Rusty.

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