The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you—this 16-day window for Bulli Beach is a tough one. There’s no standout swell, and the conditions are messy for most of the run. The first real chance to get wet doesn’t come until Monday the 14th, and even then it’s pretty ordinary. There’s a big gap before that with nothing worth paddling out for.
Let’s kick it off with Monday the 14th. Early morning you’ve got a light NNE breeze holding clean, with a small 4ft NE swell ticking over at a short 7 seconds. Combined energy is moderate at 130, but the waves are just surfable—nothing to write home about. The afternoon drops right off to 0.7ft, so don’t bother.
Tuesday the 15th is a write-off: the wind swings S and cross-on, chop builds, and the same puny 4ft NE swell gets messy. Combined energy is 163, but it’s all windslop. Wednesday and Thursday are worse—tiny, chopy, and blown out with periods of fresh breezes. Not a single decent wave.
For a moment there, Friday the 18th morning looks promising with glassy conditions and a 3ft ESE swell at 7 seconds. Combined energy hits 105, but the waves are again just surfable, nothing special. The glassy wind is a major positive though—it’ll look clean, but small. Saturday the 19th afternoon has a light NE cross-off breeze and a 2ft E swell at 11 seconds, giving a bit more shape but still tiny.
Now, the only real glimmer in this whole outlook is Monday the 22nd? No, that’s a dud too. Let me re-check—the weekend of the 25th and 26th actually shows a pulse. Friday the 25th morning has a cross-off NNE breeze with 4ft from NE at 6 seconds, combined energy 93, and it’s clean. But the standout is Friday afternoon: glassy, 4ft NE at 6 seconds, combined energy 132. That’s the best wave of the period—still short period so it’ll be a bit crumbly, but clean and fun for a confident surfer. Saturday the 26th morning is also glassy with 4ft NE swell at 7 seconds, energy at 139, and that’s your second best window—again, small but clean.
The water is about average for the time of year at 64°F. Crowds at Bulli Beach can show up sometimes, so keep an eye out on those glassy mornings.
Bottom line: there’s no big swell or epic day. The best bet is Friday the 25th afternoon or Saturday the 26th morning with glassy conditions and waist-to-chest high NE swell. It won’t blow your mind, but it’ll be the cleanest waves on offer. The rest is mostly a flat, choppy mess.
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.
