The Lowdown

Alright, let me get a read on the situation for Sandy Beach over the next couple of weeks.

Honestly, it’s a bit of a rough stretch ahead. We’re looking at a long, frustrating gap for any kind of decent surf right from the start. There isn’t a single session that jumps out as a "go" for the next 16 days. The first chance for anything that isn't a total write-off doesn't even show up until Saturday the 5th, and even that is just "marginal" at best.

The main issue is that the wind is stuck on a cross or cross-onshore hate train from the ENE, just absolutely chewing up the surface. We’re looking at lumpy, cross-chop conditions for the vast majority of the period. The swell comes through with some moderate to strong energy (values like 1421 and 2739 in the mix), and there are some decent-sized pulses around the 8ft mark on the 5th and the 8ft on the 7th, but the wind just murders the quality. It’s all short period, messy windswell, only really showing any longer period stuff from the SSW much later, but those waves are tiny.

For a spot like Sandy Beach that’s a beach and reef set-up, a long period groundswell from the SSW is more of a point break or reef wave, so the little pulses we see on the 16th and 17th aren’t going to do much here with the wind still junk. The combo of strong, cross wind and these mushy, choppy waves makes it look more like a kite session than a paddle session, to be honest.

The water temp is running pretty average for this time of year, nothing strange going on there. But with the crowds often being a factor here, you’d at least want the waves to be worth it, and they just aren’t.

Don’t sweat it too much, though. This area can turn around. It’s not a usual pattern to be this blank for so long, and forecasts change. Keep an eye on it, but for now, I’d save the wax.

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.
