San Diego
During the months of May and June, known as "May Gray" and "June Gloom," the sun remains hidden much of the day behind a thin veil of high fog. The hottest months, with temps in the eighties, are August, September, and October, when hillsides are golden-brown. A little rain falls during winter, which is the best time to view the natural landscape at its greenest. The combination of ocean, coastal canyons, and mountains to the east creates a variety of microclimates. A 10-degree temperature difference can occur within as little as 15 miles.
