No. Even now, in the longest days of the year, the sun sets at 10pm, and we're not even into the hottest days of the year for another month or two as the days continue to get shorter again.
The numbers you cite are from last year, which was unusual historically as records, not the norm. The sunset in the hottest month will be 9pm, and those highs of >30C are experienced for less than one week. I think you're missing the point of the parent posters where it's over 25C in the large parts of the US for 3-4 months of the year.
