Alright, Rusty here. Let's talk about what's on offer at Sixtynine.
Alright folks, it's pretty quiet out there for most of the next two and half weeks. We've got a long dry spell to start, with nothing really happening from now until around the 14th of July. The water's sitting at a warm 80° and feels a touch warmer than normal for this time of year, but there's no energy in the water to work with.
The first real whisper of life shows up on Tuesday the 14th in the afternoon. The swell is tiny, just 2ft from the West, but look at that wind – glassy conditions. The combined energy is picking up to 193 (moderate energy), and while the waves will be small and a bit ordinary, it’s at least surfable. The period is a long 16 seconds, so those sets will be slow and lined up, but with barely 2ft of swell, don't expect much push.
Things start getting a bit more interesting on Wednesday the 15th. The morning is still marginal with a cross breeze, but by the afternoon, the wind goes glassy again. The swell holds at about 3ft from the West, with a period of 15 seconds and a moderate energy reading of 302. The report says "expect good surf conditions" for that afternoon window. It’s small, but for this stretch, that's the pick of the bunch. The west swell direction isn't the absolute optimum for Sixtynine but it's clean and glassy, making it the standout session of the whole forecast.
After that, we see a bit of swell hanging around through the 16th and 17th, but the winds are a bit more mixed, and it drops back down. There's another glassy window on the afternoon of the 17th, but the swell is dropping (about 2ft, 212 energy). Beyond the 18th, we're back to tiny, weak waves and mostly poor conditions, with just a few glassy moments on the 19th and 20th, but the swell is barely 1ft and 1ft.
So to sum it up: the first week is a total write-off. Your best bet, and really the only standout, is the afternoon of Wednesday the 15th of July. It's not a big day by any stretch, but clean, glassy 3ft West swell with that long period will be the most fun you'll have. The afternoon of the 14th and the 17th are runners-up if you just need a paddling fix. After that, the window closes up again.
Stay tuned, forecasts can change.
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.
