Why june gloom

Inland temperatures are high. A weakening of the downward motion aloft allows for the marine layer to move further inland and a little lower inland temperatures. Slight upward motion in the upper atmosphere allows the marine layer to move well inland but tall coastal mountains inhibit further penetration.

Geography, ocean currents and weather patterns conspire at this time of the year to cause overcast mornings and occasional coastal drizzle. The condition is mostly confined to late spring and early summer. Low pressure in the Gulf of Alaska and the Pacific Northwest promotes strong west to northwesterly winds along the coast, while high pressure lies to the east of California.

Cool ocean water produces a heavy, moist marine layer, which is pushed inland by onshore flow throughout most of May and June. Northwest winds slow down south of Point Conception and turn toward the Southern California coast during the morning hours.

A counterclockwise spin called a Catalina eddy develops. This eddy behaves much like a low-pressure system. The clouds are trapped beneath an inversion layer of warmer air, which acts like a lid or cap.

Gray conditions seem to aggravate Northern Californians, but many SoCal residents think of June gloom as the break before the scalding months of July, August, and September arrive. And if you're going to a Southern California beach in the summer, you also need to know about red tide. At its best, it can be as mesmerizing as the Northern Lights, but at its worst, it coats California beaches with a smelly, frothy mess. Actively scan device characteristics for identification.
