This national weather map, from today's San Diego Union-Tribune, isn't detailed enough to tell you what's going on here. If you could zoom in on the southwesternmost corner of the country, you'd find green like the north of Canada! I kid you not: the San Diego phenomenon called "June Gloom" - cloudbanks squatting on the coast, blocking the sun and keeping temperatures low - has extended all summer this year. Someone coined the term "Summer Bummer" for it. For me, coming from New York's hottest month on record, it's quite a shock. I think you could plot New York City's temperatures of the last month and they'd never intersect San Diego's. NY's nighttime lows were higher than SD's daily highs!
