Living with Corn’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
210 frost-free days in zone 7b. The last frost comes by Apr 6 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Nov 3.
Months with highs of 62–84° and lows of 40° or more: April, May and October.

Warmer than it used to be
The last 30 years in Corn averaged 1.0° warmer than the 1900s. The biggest change is in January (+2.5°).
A smaller shift than in 76% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
