However, neither the astronomical nor the meteorological calendar can capture the lived experience of spring across the vast and varied geography of the United States. The country spans nearly 3,000 miles from east to west and stretches from the subtropical latitudes of southern Florida to the near-arctic conditions of northern Alaska. Consequently, the "first day of spring" is a moving target. In Miami, Florida, the cool, dry "winter" gives way to warmer, humid spring conditions as early as February. In contrast, a resident of International Falls, Minnesota—famously known as the "Icebox of the Nation"—might still experience sub-zero temperatures and heavy snow in late March. The wave of spring creeps northward at an average rate of about 15 miles per day, but this progress is heavily modified by elevation (with high-altitude locations like Denver remaining cold) and proximity to large bodies of water (which delay spring in coastal regions like the Pacific Northwest). For a farmer in Iowa, spring begins not on March 1 or 20, but on the first day the soil is warm and dry enough to plant.
The Vernal Equinox occurs when the sun passes directly over the equator, resulting in nearly equal day and night length across the globe. 2. Meteorological Spring Meteorological Versus Astronomical Seasons | News when is spring in united states
