The Lowdown
G’day, I’m Rusty, and here’s how the surf’s shaping up at Bulli Beach over the next couple of weeks.
Right now, it’s a bit of a flat spell. We’ve got a long run of poor surf through to the 17th, with tiny knee-high waves around 1 to 2 ft from the ENE, and combined swell energy sitting weak at just 17 to 55. The wind’s mostly cross-off or onshore, so nothing worth paddling out for. There’s a gap of several days where it’s basically unsurfable, so don’t get your hopes up.
Things start to change around the 18th and 19th, with the swell bumping up to 5 to 6 ft from the E and ESE, but the period is short (7–8 seconds) and the wind’s messy—onshore or cross-onshore. Combined energy climbs to moderate levels (219–524), but it’s still marginal at best. Not worth rushing down for.
The real standout arrives on Saturday the 22nd. That morning we’ve got a clean 6 ft swell from the ENE with an 11-second period—nice groundswell energy—and light offshore NW wind. Combined swell energy is strong at 711. It’s an advanced break and fairly consistent, so expect some power. The NE optimum swell direction lines up well here. Crowds are sometimes an issue, so pick your bank. This is the best on offer.
The good run continues into Sunday the 23rd, with similar 6 ft ENE swell, another 11-second period, and light cross-off N winds. Energy remains strong at 711. It’s still quality, but by afternoon it drops off a touch.
After that, the wind stays cross-off through the 24th and 25th, but the swell drops back to 4–6 ft with shorter period (8–10 seconds) and energy around 379–517. It’s clean but less punchy—worth a look if you’re keen but not a standout.
Late in the outlook, around the 26th and 27th, the swell fades to 2–3 ft with weak energy (96), and conditions get ordinary again. Water temperature is about average for this time of year, nothing unusual.
Best bet: hit Saturday the 22nd or Sunday the 23rd for the cleanest, most powerful waves.
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.
