The Lowdown
Alright, let's get into it. Old Rusty here, looking at the charts for the stretch ahead. We're fixin' to have a long, quiet spell, so don't get your hopes up for any hero sessions this side of the month.
First up, we're talkin' about Whitsand Bay and Tregantle. The water is sittin' at a touch warmer than normal for the time of year, about 64°F, so that's a little bonus if you're getting in. But honestly, for the next several days, it's a real struggle. The swell is tiny, the period is all over the place, and the wind is just never really on our side. It’s a classic flat spell settling in.
Saturday the 12th sees a sloppy, onshore 3ft swell from the SW with a shocking 4-second period and a fresh breeze blowing 19 mph right on it. The combined energy is a weak 45, and it’s just ugly. By Sunday the 13th, we get a bit of a longer period swell (10 seconds) from the WSW at 3ft, which bumps the energy up a tick to 141, but the wind is still messy and the forecast says poor conditions. That pattern of tiny, wind-affected waves just repeats itself day after day.
We get a little tease on Wednesday the 16th, with the swell period climbing to 11 seconds and energy at 129, but the cross-shore wind keeps it lumpy and unrideable for a clean wave. There's a solid week of this, really: nothing above 3ft, always with some cross or onshore breeze, and it’s all rated as poor.
The best of a bad lot might be the morning of Monday the 21st. We get a glassy morning with zero wind, but the swell is a pathetic 1.0ft with a long 14-second period. That long period swell is really only gonna stand up on a point or reef if it had any size, but here it's just gonna drib through. The energy is only 52. It's a paddle and a tan, not a surf. After that, the second week just fades into nothing, with swell dropping to 0.3ft and 0.7ft for days on end. Even with some clean, cross-offshore winds on the 24th and 25th from the ESE at 15-22 mph, there is simply nothing to ride. The combined energy values are down to single digits.
Honestly, there is no standout session in this 16-day window. If you are absolutely desperate, maybe that glassy Monday the 21st morning gives you a few ankle-biters, but that’s it. For everyone else, this is a solid blank run. Don't break your neck checking the charts for a while. Forecasts can change, but right now it's looking grim.
Stay dry, friends.
Rusty.
