But no, 2024 isn't the warmest June in history. That honor belongs to the year of Dad's favorite hot weather stories - 1933.

If you look at the chart titled "Contiguous U.S. Maximum Temperature" for June, the nine hottest Junes on record are, in order of highest temps, 1933, 2021, 1988, 2016, 1918, 2024, 1936, 1394, and 1911 - six of the nine were in the 20th century, with five being before World War 2.

That doesn't seem to show much of a trend.

Add to this the fact (again, from a government source, and the Environmental Protection Agency to boot) that the air quality is better today than it has been in many decades, with specific pollutants dropping dramatically.
