Alright, I’m looking at Sandy Beach here and, honestly, for a spot that usually can fire, this 16-day stretch is about as frustrating as a flat spell in July. The wind is just locked in from the ENE for days on end – fresh to strong cross-shore breezes – and that’s going to leave the surface lumpy and chopped up. There’s a lot of wave energy moving through, but none of it is lining up with the optimum swell direction the spot wants, which is ESE. The water temp is sitting at a normal 79°F for this time of year, so no surprises there.
The first few days, from Thursday the 2nd through Sunday the 5th, are a write-off for a paddle surfer. You’ve got small swell, around 2ft to 5ft, but it’s coming from the ENE or a long-period SSW/S direction with a period over 18 seconds, which can make a beach break like this tricky – it might just close out or break too straight. Plus the wind is a fresh 18–22 mph cross-shore. The combined energy is moderate, getting up to 946 on Sunday morning, but it’s messy. Not worth suiting up.
Then from Monday the 6th through to Saturday the 11th, the swell picks up a bit, 6ft to 7ft, but it’s all short-period ENE windswell, 7 to 8 seconds, with strong cross-shore winds at 25 mph. The energy is still in that moderate range, around 345 to 835, but the wave comment for every single session says "poor surf conditions." Honestly, this setup looks more interesting for kite surfing than paddle surfing – the wind is strong enough and the chop will be there.
There’s a glimmer on Sunday the 12th morning, with a 3ft SSW swell and a period of 17 seconds, but again the wind is cross-shore from the ENE at 22 mph. The combined energy is moderate at 666, but the wind will wreck any chance of a clean face.
From Monday the 13th through to Friday the 17th, it’s more of the same. Swell heights hover around 5ft to 5ft, mostly short-period ENE windswell, with a couple of brief 3ft SSW pulses. The wind backs off slightly to a moderate to fresh 15–22 mph, but it’s still cross-shore. The wave energy drops to the low-to-mid hundreds, and the wave comment never changes: "poor surf conditions." There’s not a single standout session in this whole window. The spot is fairly consistent, so it tends not to stay poor for long, but this run is a long, gusty stretch of nothing good.

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.
