The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day outlook for Bulli Beach is a tough one. We’re staring down a long, flat spell with barely a ripple worth paddling for. The first real sniff of anything rideable doesn’t show up until Tuesday the 15th of September, and even then, it’s nothing to write home about. Let’s walk through it.
For the first ten days, it’s a desert. From now through to Monday the 14th, the swell is tiny, mostly under 2 ft, and often just 0.3 ft or 0.7 ft. The combined wave energy is pitiful, barely cracking double digits – values like 9, 35, 4, and 20 (weak energy). The wind is a mixed bag, but it doesn’t matter when there’s no wave to surf. You’ll see some glassy mornings, like Friday the 11th with a glassy ENE 5 km/h (3 mph) breeze and a 0.7 ft, 15-second period swell, but it’s just not enough to move you. The water temperature sits at 64°F, which is about average for this time of year, so no surprises there.
Then we hit Tuesday the 15th of September. Finally, a pulse. The Tuesday morning brings a 4 ft swell from the NNE with a 7-second period – short period, so it’s windswell, not groundswell. The combined energy jumps to 151 (moderate wave energy), and the wind is a light cross-offshore from the NNW at 10 km/h (6 mph), keeping it clean. This is the standout of the whole outlook. It’s not epic, but it’s surfable, and after such a long dry spell, it’ll feel like a gift. The break is a beach and reef setup, exposed to the swell, and the NE optimum direction matches the guidance, so it’s got a bit of potential. Crowds are possible here (sometimes), and with nothing else on offer, expect a few locals out.
After that, it fades again. The Tuesday afternoon drops to 3 ft with a cross-offshore W 20 km/h (12 mph) wind, and the energy plummets to 77 (weak). From Wednesday the 16th onwards, it’s back to tiny waves, mostly 0.3 ft to 1 ft, with weak energy readings (under 33) and onshore or cross-onshore winds. The rest of the second week is a write-off. So, if you’re keen, pencil in Tuesday the 15th morning. Otherwise, it’s a long wait.
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.
