The Lowdown
Alright, Rusty here again, giving you the same outlook in feet and miles.
So, for Slip Point (Clallam Bay), we’re looking at a pretty barren 16 days. The first rideable surf doesn’t appear until Tuesday the 8th of September, and even then it’s ankle-biters. The entire stretch is dominated by tiny swell and weak energy, with a few moments of clean, glassy conditions but nothing with any real push.
Tuesday morning the 8th: clean cross-off breeze from the ENE at 3 mph, swell a tiny 2 ft from the west, period 10 seconds, combined energy a weak 50. By Tuesday afternoon, the wind goes glassy, swell nudges up to 2 ft from the west, period still 10 seconds, energy 68. It’s surfable, but very ordinary. Water temp is 55°F, a bit colder than what’s normal for this time of year.
Wednesday the 9th is the pick of the bunch. Morning brings a cross-off east wind at 6 mph, swell 2 ft from the west, period 12 seconds, and the combined energy hits 136 – moderate. That longer period gives the waves a bit more shape and grunt, but the size is still tiny. Clean, but don’t expect any barrels.
Thursday the 10th sees the swell jump to 4 ft from the west, but the period drops to 8 seconds and the wind turns cross-onshore, making it messy and weak. Energy is moderate (181–200), but quality is poor. Friday the 11th is flat and glassy in the morning, then a tiny 1.0 ft WNW swell in the afternoon.
Saturday the 12th morning is glassy with 2 ft west swell, period 10 seconds, energy 68 – surfable but ordinary. Afternoon gets ruined by a 9 mph cross-onshore. Sunday the 13th morning is glassy with 2 ft west swell, but the period is a short 7 seconds, so it’s weak and bumpy.
From Monday the 14th through Tuesday the 22nd of September, it’s almost totally flat. A few mornings with clean cross-off winds and tiny 1.0 ft to 1 ft WNW swells, but the energy is in the single digits or low teens – not worth the effort. The last week is a complete blank, with no swell for days on end.
If you’re determined, Wednesday morning the 9th is your only real chance – that 2 ft west swell with a 12-second period and clean cross-off wind is the closest thing to a standout. Otherwise, bring a longboard and a lot of patience.
Rusty.
