Meteorological autumn begins September 1st. This season is defined by cooling temperatures and the brilliant changing of leaves, particularly in the Northeast and Midwest. September often retains summer's warmth (Indian summer), while October brings crisp air, pumpkin patches, and Halloween. The autumnal equinox (around September 22-23) marks the return of longer nights. November is a transition month, often gray and chilly, culminating in Thanksgiving—a holiday that officially closes the harvest season and leads into winter preparations.
Winter officially starts on December 1st, though the winter solstice (around December 21-22) brings the shortest day and longest night of the year. December is festive, with holiday decorations and early snowfalls in the north. January is statistically the coldest month for most of the US, bringing blizzards to the Midwest and Northeast, while the Southwest enjoys relatively mild temperatures. February remains frigid but offers a hint of hope with events like the Groundhog Day tradition and the Super Bowl. This season is characterized by indoor gatherings, snow sports, and the struggle against ice and cold. us season months
Meteorological spring begins on March 1st and runs through May. This season is universally associated with renewal and transition. As the vernal equinox (around March 20-21) brings longer daylight, temperatures begin to rise. In most of the country, March can be volatile—bringing the last of the winter snow in the Northeast or the first tornadoes in the Plains ("Tornado Alley"). By April, rain showers are common, famously "bringing May flowers." May is often mild and lush, a prelude to summer heat, marked by celebrations like Memorial Day, which unofficially kicks off the warm-weather season. Meteorological autumn begins September 1st
