Regional context

In Reading, NOAA NCEI 1991-2020 normals put January near 30°F and July near 78°F — a 47°F seasonal arc — with about 40.6 inches of precipitation over 187 rainy or snowy days.

Rainfall in Reading stays even across the calendar: May tops out at 4.4 inches over 18.2 rainy days, and September still logs 2.3 inches across 13.0 — a narrow range for Reading. That even rhythm groups Reading with places like Lockland, OH, Arlington Heights, OH and Amberley, OH.

Around mid-April, Reading sheds its freezing nights — peas, lettuce, spinach, and radishes go into Reading's beds. Reading's heat-lovers — tomatoes, peppers, squash — hold off until Reading's frost risk clears, 10-14 days on. Frost returns to Reading near mid-November, ending the tender-crop season. A creek-bottom lot in Reading can lag Reading's last frost 7-10 days behind a south slope.

Similar climates: Lockland, OH, Arlington Heights, OH, Amberley, OH, Dillonvale, OH, Lincoln Heights, OH.
