No. Check out any standard work on calculating 'wind chill' effects.
If the air in front of the car has an RH of 5% and you can raise it to
15%, you make a _very_ significant difference to the cooling properties
of that air - even if you don't change its temperature.
This is why you Yanks always find England so cold. It's the same
temperature as back home, but the humidity is so much higher. Plus the
heating and plumbing in most hotels and even many private houses flat
doesn't work ... but I digress.
