The Lowdown

Alright, folks, Rusty here. Let's be straight with you. Looking at the charts for our stretch of coast, this isn't a week for epic tales. The ocean’s gonna be doing its own thing for the most part, and we're just going to have to work with what we've got.

The whole 16-day window is a tough one. The swell energy is mostly weak, with values hanging around the low to mid-100s at best. We'll see a brief pulse of moderate energy on Tuesday the 18th, with combined energy hitting 223, but it's messy and blown out. We then go quiet again until the tail end of the week after. It’s a long stretch of small, onshore dribble, with some clean windows but nothing with any real push. The first real glimmer of hope doesn't show up until Sunday the 23rd, and even then, it's not huge.

Let's break it down. The first few days are a write-off. Thursday the 13th has a 3ft WSW swell at 10 seconds, but the wind is cross-onshore and it’s just going to be bumpy. The swell fades fast after that, dropping to 2ft on the 14th and then to 2ft and 1ft over the weekend. There's some clean conditions in there, but with waves that small and weak, you're just bobbing around. The onshore winds pick up strong on Tuesday the 18th, with 5ft of short-period slop blown out by a fresh breeze. That’s a waste.

Now, the standout window. It’s all about the last few days. Whitesand Bay gets a little pulse mid-week, but the real event is Sunday the 23rd. We've got a 3ft swell at 8 seconds, but the energy is moderate at 175, and the wind is cross-offshore from the SE. That’s clean. Monday the 24th also has some push, with 4ft from the N, but it’s a shorter-period swell and the energy is a bit weaker. The wind stays clean, making it surfable but not spectacular. The crowd factor is a concern, as it can get busy when the conditions finally align.

One more thing to keep an eye on: the water temp is 63°, which is 1° warmer than usual for this time of year. Not a big deal, but it's something.

So, for the best of a rough bunch, mark your calendar for Sunday the 23rd and Monday the 24th. It won't be world-class, but it's clean, there's some energy, and you can get a few. For the rest, you might be better off finding a hobby that doesn't involve a wetsuit. This is a classic run of small, wind-affected surf.

Rusty.

A general guide to surfing at Whitesand Bay can be found by selecting the local surf guide option on the grey menu.

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 Whitesand Bay 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.
