Heat in Santa Clara Valley Including San Jose, California

Daily record broken in Gilroy of 106 previously 105 in 1961.

Strong high pressure over the Four Corners brought a hot and dry air mass to the Central Coast and Bay Area in mid June. Hot daytime temperatures for multiple days in the triple digits resulted in record breaking heat for the interior portion of the region. Higher elevation areas reported daytime highs in the 100s with overnight lows in the 70s and 80s. Several sites broke daily record highs on June 17th. The heat lasted into the start of that coming weekend and resulted in one fatality in San Jose. Additionally, persistent hot/dry conditions along with near record dry fuels allowed for the development of the Willow Fire in Monterey County.
