It is humid and warm in NYC but it hasn't been this year yet. But it will come and the inside of apartments will be amplified.

Most building are side by side with no windows on the side. And unites tend to only have windows on a single side which means it's impossible to get airflow.

As for radiators some can be adjusted but many are binary, either on or off. You could always turn one off for awhile too. They stay warm for quite awhile when off.
