The Lowdown
Alright mates, Rusty here. Let’s talk about what’s happening on the coast over the next couple of weeks.
It’s gonna be a slow start. The first few days are blowing hard with messy cross-off winds, nothing worth paddling out for.
Your best chance comes on Saturday the 5th. Early morning, the wind goes totally glassy, and we’ve got a clean 5ft WNW swell with a nice long 12-second interval. That’s real groundswell energy, and the water temp is about 63°F, which is normal for this time of year. That session is the one to circle on the calendar. Later in the day it drops a bit but stays clean.
Mid-week is when the ocean wakes up. Monday the 7th brings a big jump in energy – combined energy over 1200 (value 1280) – with a 7ft W swell and a long 12-second period. But the wind is cross-shore and it’s lumpy. That kind of size is only for the experienced. Tuesday the 8th is similar, big and messy. Beginners, stay on the sand those days.
After that, it fades out. The weekend of the 12th and 13th has a few small, ordinary waves but the wind is up again. The last week is basically a bust with gale-force winds and tiny swell.
Bottom line: Saturday the 5th morning is your window. The big mid-week stuff is for the hardcore only.
Rusty.
