April 4th in Stamford sits squarely in meteorological no-man's-land — expect a high near 56° and a low around 36°, but history shows anything goes. Temperatures have swung from a balmy 73° in 2010 to a bitter 21° in 1962, and there's a coin-flip chance of rain with a small but real 2% shot at snow.

Summer is the star of the Stamford calendar, with highs peaking around 85-86° in mid-July before a gradual fade through fall. Winters are cold but not brutal, with January highs averaging just 37-38°. If you're watching the umbrella, late May through early June is the wettest stretch of the year.
