The climate in the Mission Valley area, particularly during the "May gray/June gloom" period, a thick "marine layer" cloud cover will keep the air cool and damp within a few miles of the coast, but will continue through the valley. This happens every year in May and June. Since the valley opens up into the coastal area, the ocean serves as a moderating influence throughout the year.
