June Gloom

|

I used to think the weather was something adults talked about because they were boring. And now that’s me, commiserating with neighbors about the state of our sky, which gave us a glorious, bluebird May and then rolled out a thick cloud carpet on the first day of June.

June Gloom isn’t just a Southern California phenomenon, and it doesn’t only happen in June. But perhaps we give it a name (and May Gray, and, in dire situations, No-sky July and Fogust) because we complain about it the most. The response from an Oregonian friend who visited this week: “Talk to the hand.”

(When I later looked at the Wikipedia entry for June Gloom, the authors concurred: “A similar phenomenon can occur in the Pacific Northwest between May and early July, though the phrase “June Gloom” is not nearly as commonly heard as it is in California due to the frequency of cloudy or overcast weather throughout the year in the Pacific Northwest.”)

Sam Iacobellis at Scripps Institution of Oceanography talked me through how SoCal’s gloom works.  Different parts of the coast offer their own complications, but generally speaking, the cold Pacific water—aided and abetted by the California Current and the upwelling—and a high pressure region, the Pacific High, conspire to form the marine layer clouds that some of us call gloom.

Usually, the atmosphere gets colder as you head up. But the cold water creates a situation where the air near the water’s surface is colder than the air above it: an inversion. The Pacific High pushes air downward, compressing it and warming it. Together, this forms a stable inversion air that can hold a layer of cloud near the water’s surface like an older brother crouching on an upstart sibling.

Gloom often dissipates in the afternoon, as sunshine warms air near the surface. The warmer air mixes into the clouds and starts to break them up.

Of course, there’s a lot more than that going on, too. The gloom is the home of a wild kind of cloud field called actinoform clouds, which, to a satellite’s eye, look like enormous leaves or pinwheels. And the ocean itself might be providing more than just cold water. Iodide released by kelp may turn into cloud condensation nuclei, which could make clouds thicker and more pervasive.

All this fascinating stuff doesn’t prevent me from being boring. But I also think I was a bit too harsh on weather as a conversational topic. Yes, it is something to talk about when there’s nothing left to say. Yet it’s also a shared experience that has the potential to affect everyone.

When someone I don’t know very well says, “this weather is making me crazy,” I feel like I really do understand, more than if she talked about how her kids or parents or work was setting her teeth on edge.

Weather connects me to other times, too. I can imagine the Chumash, who lived on this coast long before the rest of us showed up, standing on the bluffs when the clouds start to break up. Those first rays of sunshine feel so needed that it almost feels like my skin is consuming them; I wonder if one of them felt this way, too.

Even when the gloom doesn’t lift all day, there are ways to enjoy it. There’s a contest that’s been going on for the last ten years or so among a few Scripps employees to guess the number of gloomy days in May and June.

I asked if there was any trick to forecasting gloom. Events that affect sea surface temperature, from the El Niño/La Niña cycles to the Pacific Decadal Oscillation may play a role in the amount of gloom. Iacobellis says the contest is really a crapshoot, but it also has a way of making the gloom seem less gloomy. Each cloud-covered day is one step closer to victory.

Each gloomy day, too, is a chance to think about what’s happening out there:  cold water, enormous swirls of clouds, that lunk of an inversion layer pinning the gray above our heads. Watch out, neighbors, here I come. And now I have even more to talk about.

  1. June Gloom–this Vancouverite has just added it to her vocabulary. It’s not a phrase that I’ve heard before but it sure captures the melancholy murk we have been suffering through on the Northwest coast. Thanks, Cameron.

  2. Thanks, Heather.

    Jennie, I don’t think I learned it until I moved south. (I have fond memories of foggy summer mornings at the swimming pool in Northern California.) That’s a beautiful shot, thanks for sharing it.

  3. The Chumash only lived along a part of the California coast–from about Dos Pueblos north through Santa Barbara, I believe. They did not live along the Santa Monica Bay, where our June Gloom comes from. Those were the Tongva, known also as the Gabrielino.

    Sorry to be picky, but I’ve even heard this mistake from a docent at the Page Museum.

  4. Hi Laura–
    Thanks so much for reading, and for your comment. Not picky at all–I live farther up the coast, where they once were, but looking back at what I wrote I can see that it sounds as if I was talking about the whole region. If I’m down your way on a gloomy day, I’ll make sure to be thinking about the Tongva. Thanks again for this.

  5. Good article, Cameron,

    I don’t think weather is boring at all. Personally, I’ve always thought of discussing the weather as a way of testing a person’s intelligence. If they think weather is boring, there’s not much in that head of theirs.

    Thanks for your coverage!
    Dave
