The Lowdown
Right then, let's have a look at what Whitesand Bay has in store. I gotta be straight with you – this 16-day window is a bit of a struggle. Every single session in the forecast is marked as poor surf conditions, so there are no standout days to get genuinely excited about. If you’re a beginner looking to get wet, there might be a window or two to mess about, but for anyone chasing proper waves, this is gonna be a long wait.
We start off with a bit of a rough Sunday, the 30th of August. The wind is howling out of the South at 19 mph, creating a lumpy cross-chop on 5 ft of swell. The combined energy is moderate at best (354), and with that short 9-second period, it’s just not shaping up. Sunday afternoon gets worse with a 7 ft SW swell but onshore wind at 22 mph – a complete mess. The water temp is sitting at 64°, which is a touch warmer than average, so at least you won't freeze while you're getting hammered by the wind.
Monday the 31st doesn’t offer any relief. The morning shows 6 ft of WSW swell but a cross-onshore wind from the NW at 22 mph keeps things lumpy. The energy is moderate (732), but nowhere near clean. Monday afternoon sees the wind switch to onshore from the West at 12 mph, which is a slight improvement, but the swell drops a touch. The whole week follows this pattern: Tuesday the 1st of September through to Thursday the 3rd offers small, weak, cross-onshore waves between 3 ft and 6 ft, with period dropping as low as 6 seconds. The energy figures hover in the double digits and low triple digits – weak stuff.
Then Friday the 4th of September throws up a big, messy lump. The morning swell hits 10 ft from the West with a period of 8 seconds, and the combined energy spikes to a strong 1191. But with the wind screaming onshore at 25 mph, this is dangerous, ugly, and only for experts – if anyone is silly enough to paddle out. Afternoon drops to 8 ft, but the wind stays strong and onshore.
We then hit a flat, quiet spell. From Saturday the 5th through to the middle of the second week, the swell drops below 3 ft. The wind dies down a bit, and we get a few clean-looking morning windows – like on the 10th of September with a light cross-offshore breeze and tiny 1.0 ft swell – but there’s no energy to surf. The combined energy is in the low double figures or even single digits. These are flat spells, not surf days.
By the end of the second week, around the 12th and 13th of September, we see clean conditions with offshore or cross-offshore winds, but again the swell is tiny – 1 ft to 2 ft with low energy (28-72). Long period swell of 11 seconds shows up on the 12th, which would be classy in proper size, but at this height it’s just a ripple.
Honestly, for the next 16 days, there's no surf worth chasing. The consistent theme here is poor quality. Given the persistent onshore and cross-onshore winds and the short, weak swell periods, the setup at Whitesand Bay looks more interesting for kite surfing than paddle surfing through most of this period. Just a blank run, I’m afraid. Keep an eye on the charts – it tends not to stay this poor forever.
