From the Summit County Citizens Voice (Bob Berwyn):
June, the second-driest month in Summit County, ended up especially dry this year, with only 0.26 inches of precipitation at the official National Weather Service site in Breckenridge, and even less — 0.19 inches at the Dillon station. Averages for the two sites are 1.37 inches in Breckenridge and 1.14 inches at Dillon, where there was measurable precipitation on two days, June 18 and June 29.
The sparse total in Breckenridge made it the fourth-driest (tied with 2006) on record, dating back more than 100 years, said weather observer Rick Bly. The driest June ever (0.06 inches) was in 1980, during another notable Colorado dry spell, followed by June 1891 (0.10 inches) and June 2002 (0.24 inches).
