Most people associate spring with flowers and mild weather. But as a transitional season, it can also produce a rollercoaster of temperatures, including serious cold spells. Wearing a short sleeved shirt one day and a parka the next, you may start to wonder when the cold will finally fade away.

The answer to that question largely depends on location. Below is a map from NOAA that shows the typical final freeze dates across the continental US. While actual weather conditions vary from year to year, the dates shown are based on climatology – a thirty-year average of temperature data.

Here in New York City, our last freeze of the season usually comes in mid-April.
