About Lightning in Massachusetts

Located at approximately 42°N latitude, Massachusetts is a coastal New England state where cool Atlantic waters generally suppress thunderstorm development, but inland areas and the Connecticut River Valley see more frequent summer storms. Thunderstorm frequency varies within state boundaries, so this page does not publish an unsupported statewide annual average or national rank.

In Massachusetts, maritime air masses interact with continental weather patterns during warm months. Peak thunderstorm activity occurs during June through August, when conditions align for the most frequent lightning strikes. With a population of 7.0 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting Massachusetts.
