The Lowdown

Hey there, Rusty here. Let’s talk about what’s happening at Bulli Beach over the next couple of weeks.

Right off the bat, I gotta be straight with you – the first week is a bit of a rough patch. We’re looking at a lot of flat, weak knee-high slop, with combined wave energy barely ticking over (52 early on, dropping to just 17-19 later in the week). The water’s sitting around 64°, which is pretty much average for this time of year, so nothing wild there. It’s a frustrating start, with onshore winds and poor conditions hanging around through Wednesday the 20th. You’d be better off waxing your board and waiting. The gap here is about eight days of pretty ordinary surf, with most days scoring a big fat zero.

Now, things start to look up from Thursday the 21st. We get a bit of a clean-up with a light offshore breeze from the northwest, and the swell picks up to a tiny but cleaner 2 ft from the ENE. It’s still small, but at least it’s rideable. By Friday afternoon the 22nd, the swell bumps up to 5 ft from the NE, and the wind swings to a light cross-offshore from the WSW. The combined energy jumps to 232, and that’s when we start talking about proper waves. This is the first standout of the run. Expect clean, lined-up sets. A good one for a Friday arvo session.

Saturday the 23rd is the pick of the lot for the whole forecast. Morning glass-off with no wind, 4 ft swell from the NE, a solid 10-second period, and combined energy at 216. It’ll be clean, fun, and with those light winds, the crowd might be a factor – this spot is no secret. It’s a beach and reef setup, so it can handle a bit of size, and the NE swell direction is bang on for Bulli. This is your window.

Sunday the 23rd keeps the quality going with a clean offshore from the WNW and 4 ft swell from the ENE, but the period stretches to 11 seconds. That’s a nice groundswell pulse, good energy (286 combined), and the offshore wind will hold it together. The longer period might make it a little more walled-up at the beach, but the reef sections should handle it well.

After that, the Monday the 24th sees a spike in size to 5 ft from the NE, but the onshore wind picks up, making it a bit messy. The combined energy hits 520 though – that’s a solid push of water. It’s more for the experts or for kites if the wind stays cross-shore. By Tuesday the 25th, the wind goes offshore again, but the swell drops back to 2 ft.

The second week fades out a bit. There’s a few more clean windows with light winds, but the swell stays under 3 ft and the energy tails off (55-68 by Wednesday the 26th). It’s pretty small and uninspiring. The last few days are mostly flat and glassy, but with nothing to catch.

So, to sum it up: wait out the first bumpy week. Your best chance for a proper session is Saturday the 23rd morning – that’s the standout. Friday afternoon the 22nd and Sunday the 23rd are also very good options. Everything else is either too small or too blown out.

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.
