The Lowdown
Alright folks, Rusty here with a look at what Bulli Beach has in store for us over the next couple of weeks. Let’s be straight up—it’s a bit of a mixed bag, with a long flat spell in the middle. But there’s some decent action bookending the period, so let’s get into it.
The first couple of days are weak. Friday the 21st of August, we’re looking at small 3ft surf from the NE, but with a short 6-second period. The morning has light offshore winds, keeping it clean, but the energy is weak. It’s surfable but nothing to write home about. Friday afternoon goes glassy but the swell drops to 3ft. It’s pretty ordinary.
Then we hit a serious lull. From Saturday the 22nd of August all the way through to Tuesday the 25th, the swell barely registers. We’re talking 1ft to 4ft waves, mostly with short periods. It’s a dead zone for a quality surf. Wednesday the 26th of August shows a bit of life in the morning—4ft from the NE with an 8-second period. Winds are light and cross-offshore, so it’s clean, but conditions turn sloppy in the afternoon with rain showers and stronger wind. Even so, the morning window is your best bet early on.
The standout window, and I mean the real standout, arrives on Tuesday the 1st of September. Tuesday morning brings clean, glassy 5ft surf from the ENE with a 9-second period. The water temp is about average for this time of year, nothing wild. Winds are glassy, making for some of the best conditions of the whole outlook. This is the morning to circle. It’s clean, has enough push, and the offshore vibe is locked in. If you’re an advanced surfer, this is the session.
Wednesday the 2nd of September morning also looks promising—4ft from the ENE, 9-second period, and glassy winds again. Another good, clean session. After that, things taper off into smaller, longer-period swell from the 3rd and 4th. The 11-second periods suggest better shape, but the size is small. By the 5th of September, we’re looking at tiny 2ft waves with offshore winds. Clean, but not much for power.
Overall, the big gap is from the 22nd to the 25th of August—a solid four days of nearly no surf. But the end of the run on the 1st and 2nd of September is where it’s at. Keep your eyes on that Tuesday. Bulli Beach is a beach and reef setup, exposed to the NE swell, so when it lines up, it can handle a bit of size. The 5ft on the 1st is right in the sweet spot for advanced surfers.
Stay patient, mates. Rusty out.

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.
