According to NASA, 2017 is on pace to be the second warmest year on record, surpassed only by El Niño-amplified 2016. This summer, in particular, has brought with it some record-breaking temperatures throughout the country and heat waves are expected to continue in the coming weeks.
But to learn exactly how much hotter things have been getting this summer, researchers at ConsumersAdvocate.org conducted an in-depth analysis to see which cities have been experiencing their most significant heat waves in recent history. Below are the 25 cities experiencing the biggest increases in average high temperatures so far this summer. The analysis considers temperatures for the months of June and July only.
Using data from NOAA's National Centers for Environmental Information, we identified cities that have experienced above average temperatures by comparing the average high temperature for June and July of this year to the same period over the previous 10 years. When a city had more than one station reporting weather data, we included each station’s data to compute the average high temperature. We then narrowed our list down to cities with populations over 100k people and picked the cities with the largest absolute deviation from normal. For summer peak temperature, we looked at the hottest temperature recorded for any station within a city. The data was pulled on August 1st, 2017.
