Record Hottest and Coldest Weather Temperatures Ever Recorded in Yosemite NP, California

Official weather records have been kept in Yosemite National Park since 1905. Some 4 million people a year visit this very popular and beautiful National Park.



Located in central-eastern California about 160 miles east of San Francisco, Yosemite has much milder weather variations in temperatures than the extremes in the state of California. Here are the record hottest and coldest temperatures ever recorded in Yosemite National Park, California.

The difference between the hottest and coldest temperatures ever recorded in Yosemite is 119 degrees. The difference between the hottest and coldest temperature records for the state of California is 179 degrees for a huge difference of 60 total degrees.

California is one of the most extreme weather states in the United States in terms of temperature variations. Mainly because the hottest temperature ever recorded in the world was recorded in Death Valley, California.

All-Time Record Hottest Weather Temperature Ever Recorded in Yosemite is 112 Degrees

The hottest weather temperature ever officially recorded in Yosemite National Park is 112 degrees which occurred on both July 22 and July 24, 1915. 

Overall, Yosemite is certainly a warm weather place during the day compared to most cities in the United States. Days when the temperature reaches 100 degree or more are not uncommon in Yosemite in the summer. The earliest 100 degree day in Yosemite occurred on June 9, 1913, and the latest 100 degree day occurred on September 20, 1913.

  • Hottest Temperature Ever Recorded in California is 134 Degrees

The hottest temperature ever recorded in the state of California and in the world is 134 degrees which occurred on July 13, 1913, at the Greenland Ranch in Death Valley. Yosemite is located about 180 miles northwest of Death Valley.

The difference between the all-time hottest temperature in Yosemite (112) and the all-time hottest temperature in California (134) is 24 degrees. A pretty big difference statistically and one has to say it can get pretty hot in both these California locations. 

All-Time Record Coldest Weather Temperature Ever Recorded in Yosemite is -7 Degrees

The coldest weather temperature ever officially recorded in Yosemite National Park is -7 degrees which occurred on January 1, 2009. While that is pretty cold it's also very unusual as Yosemite has only had seven days when the temperature dropped below zero since 1905.

Even though Yosemite is a warm weather place during the day in summer it can get below freezing here in every month of the year except July and August and both those months have had days when it was exactly 32 degrees. The latest below freezing date in Yosemite was on June 30, 1913, and the earliest below freezing date was on September 5, 1912.

  • Coldest Temperature Ever Recorded in California is -45 Degrees

The coldest temperature ever recorded in the state of California is -45 degrees, which occurred on January 20, 1937, in Boca. The town of Boca is now mostly gone submerged under the Boca Dam which was built in 1939 and is located along Route 80 north of Lake Tahoe.

The difference between the all-time coldest temperature ever recorded in Yosemite (-7) and the all-time coldest temperature in the state of California (-45) is 52 degrees. A huge difference.

Overall, Yosemite National Park has a much milder climate from a temperature perspective than the extremes in the state of California and in most places in the United States. Yosemite can get very hot in the daytime in the summer but at night it can also drop below the freezing mark in the park for most of the year.
