April 4th in Leawood typically lands in that pleasant shoulder-season sweet spot, with highs averaging 61° and lows around 39°. The date has swung from a balmy 79° back in 1967 to a teeth-chattering 30° low just one year later in 1968.

A single day in September 1970 dumped 5.19 inches of rain, and even April isn't immune to big snow — 8 inches fell on April 9, 1961.
Summer is the main event in Leawood, with mid-July highs averaging 88° and the thermometer staying in the 80s from June through September. If you're avoiding the heat, January and February are your best bet, though you'll trade warmth for highs in the upper 30s and low 40s. Pack an umbrella for early summer — the week of June 11–17 is historically the wettest, averaging 1.68 inches of precipitation.
