The Lowdown
Alright folks, Rusty here. Let’s have a look at what Sixtynine has in store for us over the next couple of weeks.
To be straight with you, it’s a pretty quiet run for a while. There’s a big gap of nothing doing from now until the first week of August, so don’t even bother checking the cam until the weekend of the 9th. The water temp is about average for this time of year.
The first real moment that might get you out of bed is Saturday the 8th in the morning. There’s a little knee-to-waist high W swell creeping in, around 2 ft, with a period of 12 seconds giving it a bit of shape. The wind will be a light offshore from the NE, so conditions should be clean. The overall energy is still pretty weak though (75), so you won’t be pulling any big moves, just a fun little cruise. Crowds are possible at Sixtynine.
After that, things start to look a touch more hopeful. Sunday the 9th afternoon sees a glassy spell with a very ordinary 1 ft wave from the WNW, but the energy ticks up a notch (125), so it’ll feel a bit more push. Still, it’s nothing to write home about.
The standout window in this entire forecast is Monday the 10th. The swell bumps up to about 3 ft from the W, with a period of 13 seconds – not a giant, but the combined energy jumps to a solid moderate 215. It’s the best we’ve seen, pure and simple. However, the wind is a light cross-onshore, so the surface will have a little bump on it. Not perfect, but it’s the most juice on offer. Tuesday the 11th and Wednesday the 12th keep things ticking with glassy windows and 1 to 2 ft waves from the WNW (energy in the 120-128 range), so if you miss Monday, those are your next best bets.
Honestly, there isn’t a true standout gem here that’s going to fire. The biggest day is Monday the 10th, but even then, it’s small and a bit bumpy. For the rest, it’s a case of small glassy waves and ordinary conditions. If you’re desperate for a paddle, keep an eye on the 10th, but don’t expect barrels.
Rusty.

Information about the Sixtynine Surf forecast
The above surf forecast table for Sixtynine provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sixtynine can be found by selecting the local surf guide option on the grey menu. Our Sixtynine 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 (Sixtynine) 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 Sixtynine 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.
