15 mins of 70+ in 1872. People would be losing their mind if this happened today.

Comparatively BOS only had 8. So definitely put an asterisk next to some of that yore data.

I wonder if the observation site was part of the anomaly.  No paved roads then but perhaps in the built-up (and treeless) section.  The initial obs site at the Farmington co-op had a major effect, with half of the 14 triple-digit highs being recorded during their first 5 years (1893-97) - also no pavement but lots of multi-story brick buildings.  Since then, only 1911 with 5 of 100+. 4 in NNE's greatest heat wave, June 1944 and Hot Saturday in 1975 reached the mark.  12 hundies in their first 19 years, only 2 in the next 111.

All I've got on the old years is this...

The late William L. Foster, from the year 1856 to the end of a busy and eminent professional career, kept a continuous record of the weather. Upon the organization of the Government Weather Bureau he became one of the first voluntary observers, beginning in 1884 and continuing until his death, August 13, 1897, when he was succeeded by the writer in that capacity. Observations were made by Judge Foster at his residence in the city proper. For several summers previous to 1897, and continuously since June 22, 1897, they have been made in the western part of the city, at an elevation seventy-one feet higher than the former station, and at a distance of three miles therefrom.

Previous to 1868 self-registering maximum and minimum thermometers, though an invention of longer standing, were not used in connection with this record. Until that year, therefore, the daily maximum temperature could not be recorded, nor the daily mean temperature, which is half the sum of the maximum and the minimum; and it should be added that the minimum temperatures recorded were only approximate, being those obtained by observation in the early morning. Since August, 1868, the maximum, the minimum, and the mean temperatures have been recorded daily.

The monthly mean temperatures contained in the following tables are not, as will be seen, the half sum of the maximum and minimum of the month; but they are, in each case, the average of all the daily mean temperatures of the month. The mean temperature of the year is also the average of all the daily mean temperatures of the year.

Cmon you can do better. For the record we are not the Mid Atlantic

I think the point is we’re now the old mid Atlantic dew wise but it’s still obviously more oppressive there.  A/C is an absolute necessity in all of sne below 2k.   Before anyone sells their home, put it in-it’s now expected.   When my wife and were first together 31 years ago, we used ac on some nights.   A/C has been on continuously this summer.
