The Lowdown
Alright, let me get a look at what we’ve got for the next couple of weeks. Honestly, it’s a real tough stretch for Whitesand Bay. The forecast is crowded with tiny, weak swell and mostly poor conditions. For the first several days, we’re talking about wave heights barely scraping 0.3 ft to 1 ft, with periods all over the place but mostly short and weak. The combined energy is low, mostly in the single digits or teens, and the wind is often onshore or cross-off, which doesn’t give us much hope for anything rideable. It’s a flat spell, plain and simple.
We’ve got a real gap here. From the start of the outlook through to about the 17th of August, it’s mostly a waste of time for a paddle surfer. There’s a tiny bump on the 12th with 3 ft swell and combined energy hitting 109 (moderate), but the wind is cross-shore and choppy, making it a messy, poor session. The 13th shows a bit more push with 3 ft and energy up to 125, but it’s onshore wind, so the quality is shot.
The real standout, if you can call it that, is on the 19th of August. We’ve got a jump in swell to 5 ft to 6 ft from the WSW, with a period of 7 seconds. The combined energy climbs to 230 and 257, which is strong. The wind is a strong cross-off from the NNE, so the waves will be clean. But this is a bigger swell, over 5 ft, so it’s not for beginners. The short period (7 seconds) means it’ll be a bit of a lumpy, wind-driven affair, not a classic groundswell. Still, it’s the only time in the whole window you’ll see decent waves and clean conditions. Crowds are possible here, so just be aware.
The 20th of August keeps the swell up at 5 ft, but the wind swings more cross-shore, so it’s less clean. The water temperature is around 62°, which is about average for the time of year, nothing unusual.
After that, the swell drops back down to 3 ft through the 21st and 22nd. The 22nd has a glimmer of hope with offshore wind from the east, 6 mph, and clean conditions. The swell is 2 ft from the W with a 10-second period, which is a better shape. Combined energy is 135 (moderate). It’s surfable, but very ordinary.
So, the honest truth is, if you’re a beginner, you’ll struggle all the way through. For the experienced surfer, the 19th of August is your best bet, but even then, it’s not a classic. It’s a long, flat run broken up by one day of average-to-okay surf. Don’t hold your breath.
