The Lowdown

Alright, grab a coffee and come take a look at the charts for Whitesand Bay. I’ve got to be straight with you—this one is a tough read. For the whole 16-day window, there’s not a single session that gets the green light. The rating is a 2/5 for a reason, and the scores are all zeros. It’s a beginner-friendly spot, fairly exposed to a WSW swell, but the wind just won’t play ball.

We start off on Monday, 31st August. The morning is a write-off with a 25 mph cross-on from the NW and a messy 6 ft swell. The afternoon shows a 6 ft swell from the WSW with a 10-second period, but the wind is still onshore and messy. The combined energy is moderate at 603, but it’s all for nothing with that wind.

Tuesday, 1st September, the swell drops to 3 ft, and the period is a short 6 seconds. The wind is a cross-on from the SW, making it choppy. The energy is weak, at 82 in the morning and 67 in the afternoon. Not worth a paddle.

Wednesday, 2nd September, the wind picks up to 28 mph from the SSW, creating a strong cross-shore mess. The swell is 6 ft, but the period is still poor at 6 seconds. Energy is moderate at 244 in the morning, climbing to 378 in the afternoon, but it’s all ugly.

The pattern continues. Thursday, 3rd September, is the same story: 6 ft, short period, fresh cross-onshore wind. Friday, 4th September, has a 7 ft swell from the west with a 7-second period, but the wind is onshore and the conditions are unknown. Energy is strong at 498.

Saturday, 5th September, is a slight improvement. The swell is 4 ft, but the period is still short. The wind is cross-on from the NW. It’s still poor. Energy is moderate at 193.

The rest of the first week and into the second is a long, blank run. From Sunday, 6th September, all the way through to Sunday, 14th September, there’s no quality surf. The swell is either too small, like 1.0 ft, or the wind is onshore, or the period is short. There’s a glimmer on Monday, 7th September afternoon, with a 4 ft swell from the WSW and a very long 12-second period, giving a strong energy of 432, but the wind is onshore. It’s frustrating.

Tuesday, 8th September, has a 4 ft swell with a 10-second period, but the wind is cross-on. The energy is moderate at 300.

Then we hit the end of the window. Monday, 14th September, the swell jumps to 7 ft from the SW with a 9-second period, and a strong energy of 898. The wind is onshore. It’s over 8 ft, so it’s for experts only, but the wind is still ruining it.

Tuesday, 15th September, is the biggest of the run. The morning shows a 10 ft swell from the WSW, with a massive energy of 1271. But the wind is a near-gale from the WSW at 31 mph, creating a blown-out, dangerous mess. The afternoon is 8 ft with a 34 mph wind. This setup looks more interesting for kite surfing than paddle surfing.

The water temperature is about 63°F, which is a touch warmer than normal for this time of year. But honestly, it doesn’t matter when the surf is this poor.

So, the bottom line: there are no good surf options in the 16-day window. The spot is fairly consistent, but the wind is a constant problem. It tends not to stay this poor for long, and forecasts can change, but for now, don’t bother.

Information about the Whitesand Bay Surf forecast

The above surf forecast table for Whitesand Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Whitesand Bay can be found by selecting the local surf guide option on the grey menu. Our Whitesand Bay 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.

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.
