Average Temperatures in 2025 Are Already Well Above Average in These US Cities

In recent weeks, parts of the United States have reported historic and dangerous heat waves. As of early July, Phoenix, Arizona, has already reported 10 days of temperatures exceeding 110°F. Record breaking heat in Dallas last month has been linked to at least two deaths. In Las Vegas and Needles, California, temperatures recently matched all-time highs of 117°F and 125°F, respectively. The latest forecasts indicate that, in most of the country – including places more accustomed to cooler climates – relief will not be coming soon.
Starting over the July Fourth weekend, temperatures are expected to approach or exceed the triple digits in parts of the Midwest, including Detroit, Minneapolis, and Omaha. By early next week, extreme heat is expected to reach the Eastern Seaboard. According to recent reports, an estimated 190 million Americans are expected to experience temperatures above 90°F within the coming days, and another 17 million live in areas that will likely report temperatures of 100°F or more.
While most of the country is used to high temperatures in June and July, data from the earlier months of 2025 show that cities across the country have already been living temperatures that are well above normal for much of the year. There are at least 14.2 million Americans residing in places where average temperatures exceed baseline trends by about 2°F or more over the first five months of 2025.
Using data from the National Atmospheric and Oceanic Administration, Climate Crisis 247 identified the U.S. cities where temperatures are already well above average this year. We reviewed data for over 200 cities, towns, and places in the U.S. and ranked them on the average local temperature between January and May, 2025. Only places where average temperatures exceed the baseline by at least 1.5°F are listed. Baseline temperatures, as classified by NOAA, are average temperatures over the months of January through May each year from 1991 through 2020.
