"According to recent climate data, San Francisco International Airport recorded an average maximum temperature of just 67(F) degrees between June 1 and July 15, making it the coldest start to summer since 1965."
"In San Francisco, only one day has reached 70(F) degrees since late May, a startling statistic that underscores the strength of this year’s persistent marine layer."
For the record, I'm not complaining one bit. I like these temperatures.
