Regional context

Per NOAA NCEI 1991-2020 normals, Ardmore runs from a 31°F January mean to 77°F in July, a 46°F seasonal spread, with near 43.1 inches of precipitation across about 173 wet days.

Rainfall in Ardmore stays even across the calendar: December tops out at 4.2 inches over 13.0 rainy days, and February still logs 2.9 inches across 12.4 — a narrow range for Ardmore. That even rhythm groups Ardmore with places like Haverford College, PA, Wynnewood, PA and Bryn Mawr, PA.

Once Ardmore passes mid-April, overnight freezes fade and peas, lettuce, spinach, and radishes can be sown. Tomatoes and peppers do best set out two weeks later in Ardmore, once nights clear the mid-40s°F. Frost returns to Ardmore near mid-November, ending the tender-crop season. A creek-bottom lot in Ardmore can lag Ardmore's last frost 7-10 days behind a south slope.
