The Lowdown

G’day, Rusty here. Look, I’ll level with you – this outlook for Bulli Beach starts off pretty flat and ordinary, so don’t get too excited for the first week. We’ve got a solid run of poor conditions from now until late August, with only a few tiny, weak windows. The combined energy is low, mostly under 100 and often way less, so it’s a lot of waiting around. But hang in there, because the tail end of the forecast, from the 29th of August onward, starts to cook.

Let’s kick off. Thursday the 20th and Friday the 21st are nothing special. We’re looking at knee-to-waist high swell at around 3 ft from the NE, with a short 6-second period. The wind is cross-off from the NNW on Thursday morning, which keeps it clean, but the energy is weak at 105. Thursday afternoon drops off to 93 and Friday morning is similar at 94. Friday afternoon goes glassy with a light northerly, but the swell drops to 3 ft and the energy falls away to 69 – it’s surfable but don’t expect a barrel.

Saturday the 22nd and Sunday the 23rd are a write-off. Swell bottoms out at 1.0 ft to 1 ft, energy is down in the single digits to 12. Glassy conditions on Sunday morning won’t save that tiny bump. Monday the 24th sees a slight lift to 4 ft from the NE again, energy up to 75–101, but Tuesday through to Thursday morning bring onshore winds, rain, and more weak, choppy surf. Not worth paddling out.

Now, here’s where it gets interesting. Saturday the 29th of August morning – that’s a standout. Bulli Beach wakes up with a solid 7 ft NE swell, a 7-second period, and a clean cross-off wind from the north at 9 mph. The combined energy jumps big time to 821 – that’s strong wave energy. This is advanced territory, over 8 ft, so only for the experts. The swell is a bit short-period, so it’ll be punchy, but the offshore wind will keep it lined up. The water temp is 65°, about normal for this time of year.

Sunday the 30th of August offers a slightly smaller but still solid day – 5 ft in the morning and 5 ft in the afternoon from the ENE, with an 8-second period. Winds are light and cross-off from the WNW, keeping it glassy and clean. Energy is in the 280–334 range, which is moderate to strong. This is a good call for advanced surfers who want cleaner, more manageable waves than Saturday’s big stuff.

The first few days of September keep the momentum going. Tuesday the 1st of September morning is clean with 4 ft from the ENE, but the real gem is Wednesday the 2nd of September. That morning brings a 5 ft ENE groundswell with an 11-second period – longer period means better shaped waves and more push. Winds are glassy from the SW at only 3 mph. Combined energy hits 436, strong and powerful. Conditions are clean and glassy, a proper session for experienced surfers. Thursday the 3rd of September morning is the absolute standout of the whole forecast: 5 ft ENE swell, 11-second period, glassy calm conditions with a NW breeze at 3 mph. The energy is 505 – very strong. This is the one to circle on the calendar. It’s clean, punchy, and perfect for the experienced crew. The long period means it’ll be best at the reef sections here, with longer lulls between sets making the paddle out easier.

Friday the 4th of September tapers off a touch with 4 ft ENE swell and a 10-second period, but still clean with light cross-off winds and solid energy around 297. A nice way to finish the run.

Overall, the first week and a half is flat and frustrating, but the last five days – especially Wednesday the 2nd and Thursday the 3rd of September – are the real deal. Crowds? At Bulli Beach, they can pop up sometimes, so get in early for the clean morning glass.

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.
