The average minimum these years is 46F/8C and the average maximum is 60F/16C.
The warmest I have had in my 43 runs in New York is 80F/27C and the coldest is 33F/1C.
The weather forecast will be more reliable the last week before the race, before that it's more "guessing".
Here is a graphical presentation of the maximum and minimum temperatures for each year. The graph on the left shows Celsius scale, and the graph on the right shows Fahrenheit scale
