The Lowdown
Alright, surfers, Rusty here. Let’s look at what’s cooking over the next couple of weeks. It’s gonna be a slow burn, but there’s a little something to aim for if you’re patient.
We’re starting off with a real quiet stretch, so don’t rush to grab your board. The first few days through to the 20th of August are basically a washout with tiny waves and bad wind. There’s a moment around the 16th where the swell inches up, but the period drops to 6 seconds with onshore wind. That’s just a bumpy, choppy mess – not worth your time.
You’ll see a change on Wednesday the 19th afternoon. The wind goes glassy, and we get some 1.2m swell from the East with a short 6-second period. The wave energy is moderate at 125, but it’s only called “surfable but ordinary”. It’s a little tease, but not the main event.
The real standout, the one to save for, is Monday the 24th of August. That’s your best chance in the whole window. We’ve got clean lines from the North-East running 1.4m with a 10-second period (that’s groundswell), and the combined energy is pumping at 327. The wind is a light cross-offshore from the WSW, making for glassy, clean faces. The morning is the pick. This is a solid window for an advanced surfer to go to work.
The days before it build nicely. Sunday the 23rd shows swell pushing energy up to 307 by the afternoon, still clean wind, but it’s only rated as marginal. Monday morning is the true peak.
It fades fast after that. Tuesday the 25th still has clean wind, but the swell and energy drop off. Then it’s back to tiny, poor conditions from the 26th onward.
Water temp is about what you’d expect for this time of year, nothing weird.
So in short: a long flat spell, then a promising Monday the 24th. Mark that day.
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.
