With the rainfall season (July 1 to June 30) ending Monday, and no rain on the horizon, this will be the 15th driest in San Francisco’s 165 year period of record. More significantly it’s the 11the driest two consecutive seasons and the 4th driest three-consecutive season. See http://ggweather.com/sf2013rain.htm
