Table - best surf conditions forecast for Whitsand Bay and Tregantle over the next 16 days.
The Lowdown
Hey, it’s Rusty. Let me break this down in feet and knots for you. Water temp is running about 64°F, which is a touch warmer than usual for this time of year, so that’s one small win.
First real chance to get something rideable comes Wednesday, September 16th. Whitsand Bay and Tregantle will see a 3ft groundswell from the WSW with a 11-second period and moderate swell energy (164). Winds are cross-offshore from the NNW at 15 mph, and it’s clean. This is the standout of the whole 16-day stretch. The swell direction is right in the sweet spot for the break, which favors a SW swell. It’s an exposed spot, but inconsistent, and it gets crowded often, so you’ll have company. If you’re hunting a wave that’s got some push and shape, this is your window.
The rest of the week and into the following days is mostly small and sloppy or just too weak. Thursday the 17th and through the weekend, the swell drops to 1-2ft, and winds shift onshore or cross-shore, making for choppy or lumpy conditions. By Monday the 21st and Tuesday the 22nd, you’re down to 1ft or less. On Tuesday morning, the wind goes offshore from the NE at 3 mph, with a 12-second period, so it’s clean, but the energy is very weak. You’ll be scratching for ankle-biters.
Midweek, from Wednesday the 23rd through Friday the 25th, mornings offer glassy or offshore conditions, but the swell stays between 0.5ft and 2ft. The period sometimes stretches out to 13 seconds, but the combined energy is well under 100. Not much power behind it.
Toward the end of the forecast, around Monday the 29th of September, a small pulse of long-period swell shows up: 2ft from the WSW with a 14-second period and moderate energy (106). Winds are cross-off from the east at 22 mph. Clean, but still small. A log might get you into something, but don’t expect much push.
If you’re looking for the best of a quiet period, make it Wednesday morning, September 16th. After that, it’s a long stretch of clean but tiny surf, with only a few windows for the patient ones.
Rusty.
