The Lowdown
Well, grab a cuppa, because the next few weeks are lookin' real quiet for Prestons. We're in a proper flat spell here, mate. For the first week, from Sunday the 9th right through to Wednesday the 20th, you're pretty much staring at nothing but knee-high dribble or less. The combined energy is mostly a measly 4 to 36, barely a ripple in the pond. There's a bit of offshore wind here and there, like Tuesday the 11th, but with only 0.3 ft on offer, that clean face is just a tease. Truth is, the surf is so small and weak it's basically a paddle board day or a swim.
Now, around Saturday the 22nd, things start to wake up. That afternoon, we finally see some juice with a 5 ft swell out of the SE, and the energy jumps to 197 – that's proper moderate energy finally. The wind is offshore from the WNW and gentle, so it'll be pretty clean. It's still only "surfable but very ordinary," so don't expect perfection. It's a beginner-friendly size, so if you're learning, that Saturday arvo is your best bet in this whole 16-day run.
Sunday the 23rd looks more messy. The swell bumps up to 6 ft from the NE (energy 350), but the wind swings onshore from the SSW, making it choppy. That's a write-off for paddle surfing, but honestly, those choppy conditions and that push might make it more interesting for the kite crew.
The last real hope is Monday the 24th. The swell is 5 ft out of the ENE with a period of 9 seconds, and energy is still strong at 336. The wind is cross-off from the WSW, so it should stay fairly clean. That's probably the best wave of the whole forecast if you ask me – a solid chest to head-high set with clean conditions. It's a bit much for beginners (over 5 ft), but for the rest of us, that Monday morning is the standout. Keep in mind, the optimum direction here is ENE for Prestons, so that Monday swell is right on the money direction-wise.
So to sum it up: the first 12 days are a total write-off for any real surfing. Saturday the 22nd afternoon gives you a little clean, learner-friendly bump, and then Monday the 24th morning delivers the best of what we've got – a decent-sized, clean, directional swell. It's not a classic stretch, but you can get one session in if you time it right.

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