===Climate=== Ashland lies within Oregon's southwest interior climate zone, in which all but the higher-elevation sites are in the [[rain shadow]] of the [[Oregon Coast Range]] to the west. The largest urban areas in this zone in addition to Ashland are Medford and [[Grants Pass, Oregon|Grants Pass]] in the Rogue Valley, and [[Roseburg, Oregon|Roseburg]] in the [[Umpqua River|Umpqua River Valley]] further north. Although the mountain peaks in this zone receive up to {{convert|120|in|mm|-1|disp=or}} of precipitation a year, the urban areas and the valleys in which they lie generally get {{convert|20|in|mm|-1}} or less. This valley climate is particularly good for growing fruit, especially pears, and for producing other crops and farm goods such as hay, grain, poultry, and beef.{{sfn|Taylor|Hannan|1999|p=57}} Cloud cover in nearby Medford varies from an average of 21 percent in July to 86 percent in December.{{sfn|Taylor|Hannan|1999|p=38}} On average, precipitation falls in Ashland on 114 days each year and totals about {{convert|20|in|mm}}.<ref name = NOAA /> The average annual snowfall is only {{convert|1.4|in|m|2|disp=or}}.<ref name=NOAA /> The average relative humidity, measured at 4 p.m. daily, is 47 percent in Medford, varying from 26 percent in July to 76 percent in December.{{sfn|Taylor|Hannan|1999|p=35}} According to the [[Köppen climate classification]] system, Ashland has a [[Warm-summer Mediterranean|warm-summer Mediterranean climate]] (''Csb''). On average, Ashland tends to be 2-3 °F cooler than Medford due to being 600 feet higher in elevation. The coolest month is December, with an average high temperature of {{convert|47|F|C|1|disp=or}}, and the warmest month is July, with an average high of about {{convert|88|F|C|1|disp=or}}.<ref name=NOAA /> The highest temperature ever recorded in Ashland was {{convert|108|F|C|1}}, observed in August 1981, and the record low of {{convert|-4|F|C}} occurred in December 1972.<ref name="WeatherChannel">{{cite web | title = Monthly Averages for Ashland, Oregon|url=http://www.weather.com/weather/wxclimatology/monthly/97520 |access-date= April 18, 2013|publisher= The Weather Channel Interactive|archive-url=https://web.archive.org/web/20140111015100/http://www.weather.com/weather/wxclimatology/monthly/97520|archive-date=January 11, 2014}}</ref> The wettest "rain year" has been from July 1926 to June 1927 with {{convert|29.77|in|mm|1}} and the driest from July 1954 to June 1955 with only {{convert|10.37|in|mm|1}}.
