The Lowdown
Alright, this is Rusty. Let's be straight with you: the next 16 days are looking pretty flat and sad around here. We've got only one spot on the radar, Deveraux Beach, and honestly, it's not looking like it's gonna give us much to work with.
The water's sitting at about 68°, which is pretty much bang on average for this time of year.
The first few days, from Tuesday the 18th through the end of August, the swell is tiny, barely 1ft to 2ft, coming mostly from the ESE. The energy is weak, barely cracking 30 or 40. The conditions are a mix of choppy cross-onshore winds and glassy spells, but with no real swell to push it, it's just a messy, flat lake. There's a glimpse of clean conditions on the 23rd morning with a 2ft ESE swell, but the period is a short, weak 5 seconds. The 25th Tuesday afternoon has a glassy window with 2ft, but it's still basically nothing.
We go all the way into the first week of September with nothing. Then, on Wednesday the 2nd of September, there's a little flicker. The morning shows a 1ft ESE swell, but the period jumps to 14 seconds, which is a long-period groundswell. The energy picks up to 98 (moderate), and the wind is light and cross-offshore, so it'll be clean. But it's still only 1ft. That's a lot of push for very little height. The afternoon then sees a 2ft E swell with a 14-second period and energy hitting 120 (moderate), but it goes cross-on.
So, the only standout, if you can call it that, is the morning of Wednesday the 2nd of September. The long period will mean long, clean lines, but it's tiny. It's a reef break, so the long period will work nicely, but the crowds are listed as "sometimes," so you might have some company for the few waves that roll through. It's a beginner spot, and even then, 1ft is a struggle.
Honestly, for the whole 16-day window, we're looking at a long gap of nothing, then a single, marginal morning. It's a blank run for the area. Sometimes it just doesn't pump.
Rusty.

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

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 Deveraux 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.
