What Is 'Junuary'? The Pacific Northwest's Gray June, Explained
Junuary, defined: why June in the Pacific Northwest turns cold and gray, how long it lasts, and how Southwest Washington endures its fifth winter.
By The Thunderbird · Weather & Tremors ·
AMBOY — Each year, residents of Southwest Washington complete the gauntlet of winter, false spring, second winter, and actual spring, and arrive at last at June — where they are met by a wall of marine cloud, a high of 61, and a light mist that is not rain, will not be dignified as rain, and does not stop. This is Junuary, and this desk hereby explains it, flatly, for the record and for the search engines.
The definition
Junuary (noun): the recurring Pacific Northwest phenomenon in which June impersonates late January with a better publicist. Symptoms include gray skies through the Fourth of July planning season, strangers in the Fred Meyer parking lot saying “supposed to break next week,” and tomatoes that have made no progress and feel judged.
Why it happens
The mechanism is real and boring, which is this region’s signature combination. In early summer, the interior heats faster than the ocean, pulling cool marine air inland — a natural onshore push that parks cloud cover over the lowlands while the rest of the country grills. The Columbia River Gorge, a sea-level slot through the Cascades, converts this pressure difference into the wind that Hood River describes at length. The clouds are, in a sense, the exhaust of the windsurfing economy.
How long Junuary lasts
Local wisdom holds that summer begins on July 5, and local wisdom is correct to within a margin of one barbecue. Data supports the folk calendar: the marine layer’s grip weakens after Independence Day, at which point the region pivots, without transition, to drought.
How to cope
- Do not plant tomatoes before Junuary concludes. The tomatoes know. The tomatoes have always known.
- The gray is not personal. It is regional. It is, per this desk’s long observation, older than the naming of the river.
- Residents requiring sun may drive east of Hood River, where the Gorge dries out and the sky resumes. Residents requiring smugness may simply wait until August, when the rest of the nation swelters and the ‘Couve sits at 78 and dry, saying nothing, the way winners do.
Frequently asked questions
Is Junuary real weather or just a joke?
Both, which is the regional condition generally. The marine-layer mechanism is textbook meteorology; the name is what people made of it. Compare “Vantucky.”
Does Junuary happen every year?
Most years. The exceptions are heat events, which the region has agreed to discuss only while pointing at the mountain and refreshing a federal monitoring page.
