Here we are in late July, and we have yet to hit 100 degrees in Austin this summer! Have we ever gone an entire year without hitting the triple-digit mark at least once? Here are some fun facts about Austin's 100 degree day history! All numbers are for the Camp Mabry climate database, which dates back to 1897, and includes readings taken over the years at U.T., the old Weather Bureau in downtown Austin, and Robert Mueller Airport.
Average number of 100 degree days each year in Austin: 12.3
Greatest number of 100 degree days in one year: 69 (1925) In 2009 we had 68!
Average date of the first 100 degree day:July 11th
Average date of the last 100 degree day: August 20th
Earliest 100 degree day:May 4th (1984)
Latest 100 degree day: October 2nd (1938)
Years without a 100 degree day: 10 (1987, 1979, 1975, 1973, 1968, 1919, 1908, 1907, 1906, 1904)
So, will we make it through 2010 without hitting 100 degrees in Austin? Doubtful. Summer still has a long way to go. Once our ground starts to dry out, and high pressure regains control of our weather, temperatures are likely to climb to that triple-digit mark.
