Which of the following 4 cities do you think will be the first one to see a daytime high lower than 70 F this fall? I'm going by meteorological fall starting September 1st.

A) San Diego: https://en.wikipedia.org/wiki/San_Diego#Climate

B) New York City: https://en.wikipedia.org/wiki/New_York_City#Climate

C) Nashville, TN: https://en.wikipedia.org/wiki/Nashvi...nessee#Climate

D) Albuquerque, NM: https://en.wikipedia.org/wiki/Albuqu...Mexico#Climate

This is a tough one, I will go ahead and say it won't be Nashville. September is generally warmer along the coast so I'll rule out San Diego but it will be close as they will likely have highs right around the 70ºF mark. I'm going to go with Albuquerque over NYC, probably wrong about this.
