The Lowdown
Alright folks, let's get this out there. It’s been a dry spell for Whitesand Bay, and I gotta be straight with you: the next couple of weeks are looking pretty grim for anyone chasing a proper wave.
Right out of the gate, we’ve got a few days of cross and cross-onshore winds messing with things. Thursday morning kicks off with a 5ft SW swell, but that 25 mph SSW breeze is going to chop it right up. The afternoon picks up a bit to 7ft, but it’s just messy. The energy is moderate, but it’s all over the place. You’ll be fighting the wind more than the wave.
The weekend doesn’t offer much relief. Friday gets a bit cleaner with a lighter NW breeze, but the swell drops to 4ft and it’s still cross-onshore. By Saturday, the wind swings back SW and we're back to lumpy conditions with 5-6ft of short-period slop. Sunday is a little less windy, but the swell backs off. This whole opening stretch is a write-off.
The first true standout comes out of nowhere. Monday, the 21st of September, we get a brief window of clean conditions. There’s an ESE offshore breeze, light as anything – dead glass. Swell is small, only 3ft, and the period is short. The energy is weak, so it won't be big, but it will be the only time the surface is smooth. This is the one for the patient surfer, the learner, or anyone just needing to get wet. It’s clean and user-friendly.
After that little tease, the wind comes back onshore and it’s back to mediocrity. We go through a flat, poor stretch from the 22nd to the 23rd with tiny waves and bumpy conditions.
Then, we get the biggest pulse of the period, but with a catch. On the 24th of September, the swell jumps up to 8ft in the morning, building to 8ft by the afternoon. The direction is WSW, but the period is short. The energy is strong. The problem? The wind is howling onshore out of the WSW at 18 mph. This sets up as a big, blown-out mess. At 8ft, it’s expert territory, and with that wind, it will be a battle, not a ride.
That’s it for the main events. The 25th brings cross-shore winds and a dropping swell. Back to poor conditions. The potential is there, but the forecast is a bust for quality.
So there you have it. The one true standout is that clean little window on the 21st. The 24th will be big and powerful, but only for the brave and the experienced. Everything else is about waiting it out.
Rusty out.
