Editing Sunnyvale, California (section)

===Climate===
Like most of the San Francisco Bay Area, Sunnyvale has a [[Mediterranean climate]] ([[Köppen climate classification|Köppen]] ''Csb''), with cool, moist winters and warm, very dry summers. Average daytime summer temperatures are in the high 70s, and during the winter, average daytime high temperatures rarely stay below {{convert|50|°F}}. Snowfall is rare, but on January 21, 1962, and February 5, 1976, measurable snowfall occurred in Sunnyvale and most of the [[San Francisco Bay Area]]. Sunnyvale was briefly hit by tornadoes in 1951 and 1998, but otherwise they are extremely rare.<ref>{{Cite web|url=http://tornado.sfsu.edu/geosciences/StormChasing/Cases/Sunnyvale/Sunnyvale.html|title=Sunnyvale and Los Altos, CA Tornadoes|work=[[San Francisco State University]], Department of Geosciences|date=May 4, 1998|access-date=October 23, 2021|archive-date=June 13, 2013|archive-url=https://web.archive.org/web/20130613194202/http://tornado.sfsu.edu/geosciences/StormChasing/cases/Sunnyvale/Sunnyvale.html|url-status=dead}}</ref><ref>{{cite web|first1=Justin|last1=Berton|first2=Steve|last2=Enders|url=http://www.svcn.com/archives/sunnyvalesun/05.06.98/CoverStory.html|title=Hit and Run: Freak tornado injures no one, but leaves behind costly damage|archive-url=https://web.archive.org/web/20090109100649/http://www.svcn.com/archives/sunnyvalesun/05.06.98/CoverStory.html|date=May 6, 1998|archive-date=January 9, 2009|access-date=October 24, 2021|work=[[Sunnyvale Sun|The Sun]]|url-status=dead}}</ref><ref>{{cite journal|last1=Monteverdi|first1=John P.|first2=Warren|last2=Blier|first3=Greg|last3=Stumpf|first4=Wilfred|last4=Pi|first5=Karl|last5=Anderson|url=https://journals.ametsoc.org/view/journals/mwre/129/11/1520-0493_2001_129_2805_fwdoaa_2.0.co_2.xml|title=First WSR-88D Documentation of an Anticyclonic Supercell with Anticyclonic Tornadoes: The Sunnyvale–Los Altos, California, Tornadoes of 4 May 1998|journal=[[Monthly Weather Review]]|issue=11|volume=129|date=November 2001|page=2805|doi=10.1175/1520-0493(2001)129<2805:FWDOAA>2.0.CO;2|bibcode=2001MWRv..129.2805M|access-date=October 24, 2021|archive-date=October 24, 2021|archive-url=https://web.archive.org/web/20211024142514/https://journals.ametsoc.org/view/journals/mwre/129/11/1520-0493_2001_129_2805_fwdoaa_2.0.co_2.xml|url-status=live}}</ref><ref>{{cite news|last=Coile|first=Zachary|author2=Emily Gurnon|title=Storm knocks out power to thousands in Bay Area; Marin commuters cut off by U.S. 101 closure|work=THE STORMS OF '98|date=February 6, 1998|url=http://www.sfgate.com/cgi-bin/article.cgi?file=/examiner/archive/1998/02/06/NEWS397.dtl|archive-url=https://web.archive.org/web/20030331091830/http://www.sfgate.com/cgi-bin/article.cgi?file=/examiner/archive/1998/02/06/NEWS397.dtl|archive-date=March 31, 2003|access-date=December 15, 2008|url-status=dead}}
