June Gloom (also May Gray) is a California term for a weather pattern that results in overcast skies with mil temperatures during the late spring and early summer. The condition is prevalent in many parts of the world where marine stratus or stratocumulus clouds are common, particularly off the western coasts of continents—especially off Peru, Namibia, Western Australia, and California. Such cloud systems are persistent year-round off the coast, yet in certain seasons they blow ashore and create the gloomy "May Gray" effect on land. The June Gloom phenomenon has also been known to occur during the early fall in California.
