How Common is April Snow?
Average April Snowfall:
- Bridgeport, CT – 0.9 inches
- Danbury, CT – 1.6 inches
- Bradley Airport – 1.9 inches
But what does that mean? Just because CT averages snow in April, does not mean that it snows every April.
Probability of Snow in April:
(Shore) Sikorsky Airport – 25% (16 out of last 65 years)
(Inland) Bradley Airport – 52% (57 out of 110 years)
Basically, you could say the shoreline would expect snow in April once every four years, while inland sections would be closer to every other year. It’s those rare years that see heavy snow in April that seem to inflate the averages.
