Boulder weather station historyThe first recorded observations for Boulder were made for several months in 1893 to 1895. Records are essentially complete from 1897 to the present (except for 1 year from 1989-1990 where there was no official Boulder station). Station locations were at various points in the western part of the city to 1912, near the Colorado campus from 1912 to 1936, and on the University campus from 1936 to 1947. The weather observations were made from 1947 to 1989 by the Boulder Fire Department, on the roof of the old Central Fire station at the western edge of the main business district until 1958 and on the grounds of the New Central Fire Station north of the boulder business district until 1989. From 1990 onwards, records are from near the NIST building on the western edge of town south of the main campus.
