The Lowdown

Alright, folks, Rusty here. Let's cut to the chase. The next week-plus at Sandy Beach is a total loss. ENE winds, onshore and cross-shore, are going to keep the ocean all lumpy and chopped up. We're talking moderate wave energy (600-700 range) with heights bouncing from 2ft to 6ft. It's all junk. Don't even bother looking at it until the 7th.

That's the big gap. From now until Monday, September 7th, there is zero quality surf. Over a week of nothing. It's a drought. You might as well go fishing or fix your board.

Then, on Monday afternoon, September 7th, the switch flips. The wind turns offshore from the NW, and it goes glassy. Clean. The swell comes in at 4ft from the SSW with a 14-second period. That's real, strong groundswell, and the combined energy jumps up to 1179. This is the day. The standout of the whole forecast. Sandy Beach is a beach and reef setup, so the long period might make it a bit walled-up, but that offshore wind will make it absolutely groomed. This is your one chance in the next two weeks to get a proper session.

The following days (the 8th and 9th) will have more size, up to 6ft, but the wind goes bad again and it all falls apart. So, it's a short window. Be there on the 7th.

Water temps are just about normal for this time of year. Nothing to write home about.

So, there you have it. A whole lot of nothing, then one perfect afternoon on the 7th. Don't miss it.

Rusty.

Information about the Sandy Beach Surf forecast

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