June Gloom

 Good to know!
Om ni planerar en tripp till södra Kalifornien borde ni inte åka i juni om ni vill ha fint väder. Vänta istället till juli  och augusti, det är då den riktiga kaliforniska sommaren anländer.

June Gloom (sometimes May Gray) is a Southern California term for a weather pattern that results in overcast skies with cool temperatures during the late spring and early summer in the mornings and afternoons. For example, June is the cloudiest month of the year in San Diego.[1]

The condition is prevalent in many parts of the world where an offshore marine layer of stratus or stratocumulus clouds is common, such as the western coasts of continents—particularly off Peru, Namibia, Western Australia, and California. Such cloud systems are persistent year-round off the coast; in certain seasons they move ashore and create the cloudy, cool effect on land.[2]

Early mornings during this period are typically foggy, with an occasional drizzle. The fog turns to low clouds by late morning and early afternoon. Finally, by afternoon, solar heating is sufficient to evaporate the clouds. Often the overcast will evaporate ("burn off") quickly in inland areas, but will linger most of the day along the coast.

In Southern California, the number of days in May and June that are "gloomy" vary from year to year. Years with warmer ocean temperatures, referred to as El Niño, may result in fewer gray days in May and June.[3] Cooler ocean temperatures, associated with La Niña, usually foretell a more gray period.

June Gloom has been reported by some Californians to bring on symptoms consistent with seasonal affective disorder.[4]
