The Lowdown
Alright, folks, Rusty here. Let’s cut to it: the next 16 days are a rough watch. We’ve got a long, flat spell starting from Friday the 4th all the way through to Saturday the 13th. Nine days of barely a bump. The swell is tiny, the period is short, and the wind is mostly cross or onshore, just ruining what little energy is there. It’s a proper lull.
Coastguard Beach is the only break in the game, and it’s a beginner-friendly, exposed beach that’s usually consistent. Not this time. The water temp is 68°F, which is about average for this time of year, so at least it’s not freezing. The wave energy is weak, mostly in the 20 to 38 range for the first week—nothing to write home about. The best you get is a brief moment on Monday afternoon the 7th when the wind goes glassy and the swell hits 3 ft from the ENE with a 10-second period. But it’s still called “very ordinary,” so that’s a one-session, nothing-special deal.
The one true standout, if you can call it that, is Thursday morning the 10th. We get a push of 4 ft swell from the SSW, with a moderate offshore wind from the WSW keeping it clean. The combined energy hits 159, which is moderate and gives it some punch. The period is 8 seconds, so it’s a short-period swell, but with offshore wind, it could offer a few decent waves for a patient surfer. The swell direction is a bit off the optimum SE, so it won’t be perfect, but it’s the best you’ll see all period.
After that, it’s a ghost town. From the 11th to the 19th, we’re looking at tiny waves, mostly under 2 ft, with weak energy and cross or onshore winds. There’s a glassy morning on Monday the 14th and another on Wednesday the 16th, but with only 0.6 ft to 3 ft on offer, it’s flat and frustrating. The combined energy stays under 100 for almost all of it. Honestly, if you’re a kite surfer, the strong cross-shore winds on Sunday the 6th and Friday the 11th might look better than anything a paddle surfer can do. For the rest of us, it’s a waiting game. Forecasts can change, and this spot is usually consistent, so don’t give up yet, but right now, there’s nothing to chase.
Rusty.
