I have lived in: interior CT, western MA, Boston area, and coastal CT over the course of 40+++ years.

Interior CT - more humid in summer, snowier, colder

Western MA - snowiest, coldest, same humidity

Boston - cold, snowy, urban heat island

Coastal CT - milder, fewer extremes, less snow, rains when it snows elsewhere, windy, late falls, cool springs (warmer springs inland), less humidity in summer.
