The Lowdown
Right, let's look at what Whitesand Bay has cooking over the next couple of weeks. I gotta be honest with you, mate – it’s a pretty grim outlook for most of it. There’s a long, quiet stretch ahead.
From Sunday, July 19th all the way through to the start of August, that’s a solid 13-14 days where the surf is mostly flat or just plain messy. You get tiny pulses of swell, mostly from the north or southwest, with periods so short (4-5 seconds) the waves just can’t get any shape. The wind is often a fresh breeze, and for a spot that needs a west-southwest swell, it’s mostly blowing the wrong way, creating chop and lumpy surface. The combined wave energy stays in the weak zone (well under 100). Not a single day scores above a 0 out of 10 until August 2nd. The water temp is about 62°F, which is 1°F above normal – just a touch warmer than average.
Now, I see a faint glimmer at the very end. On Sunday, August 2nd, things finally pick up a little. We get a 3ft swell from the WSW with a 6-second period. The combined energy jumps to 81 (moderate energy), and the wind turns to a light, cross-off breeze from the north, so the surface will be clean. It’s still only a 1/10 day, described as "surfable waves but very ordinary conditions," but after that long dry spell, it’s your only real window.
The next day, Monday the 3rd, the period bumps up to 9 seconds and energy hits 59, but the wind picks up to a fresh cross-off and the size drops to 2ft. So, that Sunday is your one and only standout – just a tiny, clean waist-to-chest-high wave if you’re on the right board. For a break that can be fairly consistent, this is a tough run. Sometimes the ocean just shuts down.
