The Lowdown

Alright, Rusty here. Let's have a look at the only show in town for this forecast period.

It's a tough stretch ahead for Sandy Beach. The next 16 days are pretty much a write-off for any decent paddle surfing. The wind is a constant problem, hammering in from the ENE or NE at 18 to 25 mph, which keeps the ocean lumpy and cross-chop ridden. For the first ten days, the conditions are just plain poor. The swell is mixed, but the energy is moderate, with combined energy readings mostly in the 500 to 900 range, but it's all blown out. There's a brief window of *marginal* surf popping up on the 5th of September, but it's still a far cry from good.

The only real standout, and it's a tentative one, comes on the 5th of September and into the 6th. A bigger, longer-period groundswell pushes in from the ENE. The swell hits 7ft on the 5th with a period of 13 seconds, and combined energy jumps to a strong 1759. That's a lot of water moving. The wind is still a cross-shore, but it drops to a moderate breeze. This long-period swell will have power, but at a beach break like Sandy Beach, it's likely to be a bit straight and hard to handle. The 6th is similar, with 6ft swell from the ENE at 12 seconds. Because of the size, this is only for experts. It's a slight improvement, but with the crowds that are often here, it'll be a battle. The first week of September is the only time you'd even look at the ocean, and even then, keep your expectations very low.

Stay keen, but not on this beach for a while.

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.
