June Gloom is a California term for a weather pattern that results in cloudy, overcast skies with cool temperatures during the late spring and early summer. While it is most common in the month of June, it can occur in surrounding months, giving rise to other colloquialisms, such as "May Gray", "No-Sky July", and "Fogust". Low-altitude stratus clouds form over the cool water of the California Current, and spread overnight into the coastal regions of California.
