The Lowdown
IMPERIAL
Alright, let’s break this down in feet and miles per hour. It’s a rough one, lads.
The full 16 days are looking bleak for any kind of rideable surf. There’s a long, drawn-out gap of nothing good.
Starting off on Monday the 20th of July, there’s a 1ft swell from the WNW, but a 15 mph cross-shore from the north is wrecking it. Water temp is a touch warmer than usual at 65°F, but it doesn’t matter when the wave energy is that weak (43). Save your energy.
Tuesday the 21st and Wednesday the 22nd show a little more size, up to 4ft, but it’s all short-period, wind-affected slop with energy still weak (under 86). Not worth a look.
Thursday the 23rd of July morning is the one glimmer of hope. A glassy 3ft wave from the NNW with moderate energy (76). No wind, clean conditions. The break is consistent, so you might find a few crumbly ones, but the description says it’s “very ordinary.” If you absolutely have to get wet, that’s your only real window.
From Thursday afternoon onward, right through to Tuesday the 4th of August, it’s a total write-off. The swell drops to between 0.3ft and 2ft, with cross-shore, cross-on, and onshore winds blowing 10 to 22 mph. The energy readings are pitiful, mostly under 60, with only a couple of days on the 26th and 27th of July showing moderate energy, but those are hammered by fresh cross-onshore winds and lumpy conditions.
A few mornings like the 29th and 30th of July look clean with light offshore or cross-off winds and a 2ft swell, but the energy is too weak (under 49) to push anything worth riding. The break is fairly consistent, but the ocean just isn’t giving us anything.
If you’re into kiting, those days around the 26th and 27th might have some juice with a fresh breeze and moderate energy, but for a paddle surfer, it’s a lost cause. This kind of dead period is pretty standard for the area when the weather patterns set in. Forecasts can shift, but as it stands, I’d say it’s time to wax the car, not the board.
