And Winter 1779-1780 is when the Continental Army was stationed at Morristown I believe where hundreds died from hypothermia. It was even worse than the previous winter at Valley Forge which is better known. 1 Link to comment Share on other sites More sharing options...
dWave Posted July 25, 2025 Share Posted July 25, 2025 3 hours ago, LibertyBell said: wow it shows that even low to mid 90s can be deadly, the length of that heatwave might be what made it so deadly. It's not on the list of longest NYC heatwaves though. Why was that heatwave in 1972 more deadly than the two longer and more extreme heatwaves in 1999 though? 1999 was second only to 1953 in heatwave length and extremes. Overnight lows matter too. Consistently staying 75+, I assume with high humidity, takes a toll. Remember AC was less widespread then as well. The lack of any time for the human body to recover overnight from the heat increases the risk. Over an extended period, days with a high low split like 98/68 can be easer to handle then 93/79 for example. Especially in urban areas, as the official temp may not fully capture real world experience inside baking apartment buildings etc. I think a lot of the precautions put in place now to deal with heat became more widespread after the deadly Chicago heat wave. Local govts issuing heat emergencies outside of the NWS warning system, cooling centers etc. 1 Link to comment Share on other sites More sharing options...

That was before they even had electricity, I can't imagine what that was like. Link to comment Share on other sites More sharing options...

Based off recent years highs (2019, 21, 22, 24,25). Not going to get there slim chance. How many times has EWR hit 105 in their entire history? I know they did it twice in 1993 -- it was their previous highest temperature ever recorded.
