Rain fell in San Francisco often in the first half of November 1876 and it would seem that the winter or rainy season, along the west coast of the United States might turn out rather wet. December averages almost a dozen days of rain in the month with rainfall totals close to 4 inches on the average. No rain fell on December 1, 1876, not on the second. In fact, not one drop of rain fell for the entire month as a persistent area of high pressure camped along the west coast for the entire month and into January deflecting storms to its north. No rain fell in area all across the northern half of California, not only in San Francisco but also Sacramento and even up in rainy Portland Oregon less than an inch feel for the entire month in one of the driest periods on record, even including today in the current era of drought in the west.
