In which season are nor'easters most likely to occur?

Nor'easters are most likely to occur during the winter season. This is primarily due to the atmospheric conditions that develop during this time of year. In winter, cold air masses from Canada often collide with warmer, moist air from the Atlantic Ocean. This clash of air masses is a key ingredient for forming nor'easters, which can generate heavy snowfall, strong winds, and coastal flooding.

Additionally, during winter, the temperature contrasts are generally more pronounced, leading to a greater potential for the development of significant storm systems. The jet stream is also positioned in a way that facilitates the development and strengthening of low-pressure systems typical of nor'easters. As a result, the combination of colder temperatures, moisture availability from the ocean, and atmospheric dynamics contributes to the frequency and intensity of nor'easters primarily in the winter months.
