Regional context

Shiloh's precipitation spreads evenly: December peaks at 3.8 inches on 14.2 wet days, while February holds 2.7 inches over 13.0 — no month dominates Shiloh's rain calendar. That even rhythm groups Shiloh with places like West York, PA, Weigelstown, PA and York, PA.

Shiloh's growing window opens around mid-April, once Shiloh's overnight lows stop freezing — sow kale, peas, spinach, and parsnips. Warm-soil crops in Shiloh wait about two weeks past Shiloh's last frost, once the soil warms. It shuts near mid-November, when freezes return to Shiloh and tender plants need cover. Within Shiloh, cold-air pooling chills low spots by 5-10°F, shifting Shiloh's local frost dates.
