Ithaca is Hot

21 07 2011

According to NWS Binghamton, the high temperature in Ithaca tomorrow is expected to be right around 99 degrees Fahrenheit (~37.2 C). Earlier model outputs suggested a high right around 102 F. Regardless, the heat index (an indication of how it actually feels, thanks to the effects of high humidity) will be right around 110. It’s not often that Ithaca flirts with the century mark when it comes to temperatures (since most students know Ithaca as a frigid windswept land, any heatwave of this magnitude should be nothing short of shocking).

Being curious, I decided to glance at the NRCC climate records to determine the last time Ithaca hit 100 degrees (non-heat index). Well, a cursory check of the last twenty years turned up squat. So, I expanded the search, and pulled all days from 1900 onward that had temperatures recorded at 100 degrees or greater at the Ithaca station. Here’s the result:

07/03/1911 101

07/04/1911 102

07/05/1911 100

08/22/1916 101

07/02/1931 102

09/12/1931 100

06/29/1933 102

07/08/1936 101

07/09/1936 103

07/10/1936 102

An almighty ten occurrences in 110 years of records. The last of which was over 75 years ago.

Expanding the threshold a little bit, I checked out the dates where the temperature reached 95 F or higher. There were 129 occurrences in 110 years, a little more than one a year (but, since heat waves tend to be longer-term events, they typically occur in spurts of a few days at a time). the last day above 95 was August 15th, 2002, when the temperature hit 96 at the Ithaca Game Farm weather station. Looking more closely, the dates break down fairly clearly – once in 2002, once in 2001, twice in 1995, once in 1990, once in 1988 (a grand 98 degrees, the highest in the past 50 years), once in 1966, twice in 1965, and a record 5 times in 1955 (the highest of which was 98). So in the past 50 years, Ithaca has broken 95 degrees only 9 times.

So, it will be a hot day, maybe even one for the record books. I’m sweating in my AC-lacking apartment as I write this a few hours east of Ithaca, and I will be very glad when a cold front moves through later this week.
