Why is my nose blocked outside in LA and New York but not in Pittsburgh or Boston?

I know it's apparently normal for many people to only breathe out of one nostril at a time
, and that certainly is the case when I'm sleeping. However, when I go outside, in many cities my nose completely clears up and I am able to breathe through both nostrils at once.
This is not true of all cities' outdoor air. I would have thought it may have something to do with pollution but then why do LA/New York not work while Pittsburgh (more polluted than New York) and Boston do?
Any ideas? Are there particular allergens that might be in the LA & New York air that are not in these other cities that keep one nostril blocked all the time?
