The Lowdown

Alright, Rusty here again, giving you the lowdown in feet and knots.

We’re looking at Trestles (Uppers) as the only game in town, and it’s a slow burner. The first week is a write-off. From Monday the 24th through the end of August, the swell is tiny—2ft or less—and the wind is mostly cross-on or onshore, making it choppy and messy. The water is sitting at 74°, which is much warmer than normal for this time of year. The wave energy is low to moderate (302 to 752), but the wrong wind kills it.

The first real standout hits on Tuesday the 1st of September. Morning sees a light rain, a clean offshore breeze from the NE at 9 mph, and a 4ft swell from the south with a 12-second period. That’s clean, lined-up surf. The combined energy is moderate (552), and the offshore wind means the waves will be smooth and hollow. This is the best of the whole run. The afternoon stays good with a cross-offshore breeze.

The middle of the first week of September sees some mixed conditions. Wednesday and Thursday have cross-on wind, but the swell holds around 4ft to 4ft from the south-southwest. Energy stays moderate (475 to 945). There’s a long 19-second period on Thursday afternoon, but the cross-on wind keeps it from being perfect.

The second standout is Monday the 7th of September. The morning is still a bit messy, but Monday afternoon turns glassy. The wind drops to nothing, the swell is 2ft from the southwest with a very long 21-second period, and the energy is moderate (716). That’s a clean, glassy session on a long-period groundswell. Perfect for a point break like Uppers, where those long lines will reel.

So, to sum it up: the best windows are Tuesday the 1st of September morning with that offshore wind, and the glassy Monday afternoon on the 7th. Everything else is small and onshore, with only brief moments of decent shape.

Rusty.
