I paraphrased the following from two National Weather Service reports:
----
...ALL-TIME RECORD DRY STREAK ESTABLISHED AT DOWNTOWN SACRAMENTO...
THE DOWNTOWN SACRAMENTO CLIMATE SITE ESTABLISHED A NEW ALL-TIME RECORD DRY STREAK OF 212 DAYS. THE PREVIOUS RECORD OF 194 DAYS WAS SET FROM MAY 13, 1880 THROUGH NOVEMBER 22, 1880. THE NEW RECORD IS MARCH 19, 2021 THROUGH OCTOBER 17, 2021.
MEASURABLE RAINFALL IS RAINFALL OF 0.01 INCHES OR GREATER AND DOES NOT INCLUDE TRACE AMOUNTS. DOWNTOWN SACRAMENTO REGISTERED 0.01 INCH ON OCTOBER 17TH.
DOWNTOWN SACRAMENTO`S PERIOD OF RECORD DATES AS FAR BACK TO 1855. DURING THE EARLY YEARS OF THE PERIOD OF RECORD, THERE WERE LARGE GAPS OF MISSING DAILY PRECIPITATION DATA THROUGH THE MIDDLE 1870S. STARTING IN WATER YEAR 1878, DAILY PRECIPITATION OBSERVATIONS BECAME NEARLY CONTINUOUS WITH MINIMAL MISSING DATA. THE CLIMATE STATION HAS MOVED AROUND THE DOWNTOWN SACRAMENTO AREA OVER THE COURSE OF TIME, AND IS PRESENTLY LOCATED NEAR SACRAMENTO STATE UNIVERSITY SEVERAL MILES EAST OF DOWNTOWN.
