G’day, Rusty here. Let’s have a look at what’s cookin’ for Sandy Beach over the next couple of weeks.

Alright, straight up – I’m not gonna sugarcoat it. The next week and a half is a write-off for decent paddle surfing. We’ve got a solid run of poor conditions starting from Thursday, July 9th, all the way through to Sunday, July 20th. That’s nearly twelve days of messy, lumpy, cross-shore chop. The wind is hammering out of the ENE at 22 to 25 mph basically every day, and it’s staying cross or cross-on, which is just ruining any chance of a clean face. The swell is hanging around 5 ft to 8 ft, but with that short period of 7 to 8 seconds and the wind just tearing it up, it’s all white water and bumps. The combined energy is moderate, sitting between 249 and 1077, but it’s all wasted energy with that wind. For a beach and reef setup like Sandy Beach, this is looking more like a kite session than a surf session for a while.

Now, there is a little glimmer in the second week. On Monday, July 20th, we start to see a shift. The swell drops to 3 ft, but the period jumps right up to 16 to 17 seconds – that’s a very long-period groundswell pushing in from the east. The combined energy spikes up to 1119 and 1435, which is strong, but the wind is still a bummer, blowing 19 mph cross-shore from the ENE. We’re still looking at lumpy conditions, so it’s marginal. The optimum swell direction for Sandy Beach is ESE, so this east swell is on the money direction-wise, but that wind is the killer.

The real standout, if you can call it that, is Tuesday, July 21st. Morning and afternoon both see that long-period groundswell hanging in at 4 ft from the east, with a period of 16 to 17 seconds and combined energy of 1246 to 1612 – that’s strong energy. The water temp is about average for the time of year. But again, the wind is still fresh cross-shore from the ENE at 19 to 22 mph. The wave comment says “marginal surf forecast or questionable tide conditions,” which is fair. That long-period groundswell will produce some nice lines, but at a beach break like Sandy Beach, it might break a little too straight. You’d want to find a bank that can handle it. The crowds here are often, so you won’t be alone, but with conditions this marginal, it might keep the numbers down.

So, bottom line: the first ten days are a total dud. The only real chance to get wet is around July 20th to 21st, but it’s a long way out, so treat it as a promising maybe. The wind will need to play ball for it to be any good. Keep an eye on 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.
