The Lowdown
Alright, this is Rusty. Let's have a look at what's shaping up for Dumps.
Right off the bat, we've got a bit of a slow start. The first couple of days are messy with that cross-onshore wind and wave conditions that just aren't coming together. Wednesday morning is a bit of a tease with a 6ft swell from the WNW, but the wind is messing it up. The water is sitting at 62°, which is a touch warmer than normal for this time of year.
Honestly, the standout window is building towards Saturday the 12th. The morning session is where you want to be. We're looking at a solid 10ft swell from the WNW, and the period is a proper 12 seconds. That's a lot of energy (2322) in the water. The wind is cross-shore with a gentle breeze, so it won't be perfect but it's the best we're going to get. This is a big one though—at 10ft, this is expert territory only. If you're not comfortable in serious size, give this a miss. It’s a fairly exposed spot so it'll be handling all that power. Crowds are sometimes a thing here, so expect some company.
The Sunday the 13th is a step down but still worth looking at with a 5ft swell from the NW and a light cross-shore breeze, but the energy drops right back.
After that, there's a long dry spell. From about Monday the 14th all the way through to the following Friday, the 18th, it's mostly poor conditions, small swell, and onshore winds. It’s a real lull. The morning of Friday the 18th shows a jump to a 7ft WNW swell at 11 seconds (1070 energy) with a light offshore wind, but it's so far out that I'd take that with a grain of salt for now.
The only other real glimmer is on Sunday the 20th. It's a week and a half out, so don't book your trip around it, but the morning is showing a 6ft WNW swell with a cross-offshore wind and clean conditions. That's a promising combination.
Bottom line: If you are an expert, be on the water Saturday the 12th morning. That’s the biggest, most powerful swell of the window. For everyone else, keep an eye on that Sunday the 20th.
Rusty.
