The Lowdown
Alright folks, Rusty here. Let’s take a hard look at the surf ahead for Whitesand Bay. Gotta be straight with you – this one’s a tough stretch.
The next week and a half is pretty grim. We’ve got a long, dry spell with barely a ripple. From Saturday the 25th of July right through until the end of the month, it’s all small, weak, and messy. Wind is mostly cross-onshore or cross, and the swell is tiny. The wave energy is pitifully low, often under 50 (15 to 45). It’s a real desert out there.
We finally get a flicker of hope on Saturday the 1st of August. The morning shows a bit of a pulse. A clean 4ft swell from the SW, with a period of 9 seconds, pushing a moderate 271 energy. The wind is light and offshore from the SE, so it’ll be clean. The score is a 2/10, but that’s a standout in this bleak window. It’s a beginner-friendly size, but keep in mind that with a 9-second period, it’s a mixed bag, not a true groundswell.
That brief moment of glory is gone by the afternoon, and we’re straight back into the doldrums. Sunday the 2nd is tiny again, and the whole next week is a washout of tiny, choppy, or cross-shore junk. The energy numbers are mostly in the low double-digits.
Then, a week later on Wednesday the 5th of August, the forecast throws a real curveball. A big 12ft swell from the WSW hits, with a 9-second period and a massive 1962 energy. That’s a lot of power. The wind is light and onshore, but the report says "marginal surf forecast or questionable tide conditions." This is only for experts. 12ft is well over the 8ft mark, so if you’re not a seasoned charger, stay well clear. The 9-second period means it’ll be a fat, powerful, and possibly closed-out mess at a beach break, better suited for a big-wave crew or maybe even kite gear.
After that, it fades back into small, poor-quality surf for the rest of the outlook.
So, to sum it up: the only half-decent window is the morning of Saturday the 1st of August. Get it while you can. The rest is a long, hard wait. The water temp is about average for this time of year, nothing weird.
Rusty.
