Regional context

In Essex, NOAA NCEI 1991-2020 normals put January near 32°F and July near 78°F — a 46°F seasonal arc — with about 45.6 inches of precipitation over 184 rainy or snowy days.

Rainfall in Essex stays even across the calendar: December tops out at 4.5 inches over 14.9 rainy days, and October still logs 3.1 inches across 11.9 — a narrow range for Essex. That lines Essex up with places like Middle River, MD, Bowleys Quarters, MD and Dundalk, MD, fed by overlapping storm tracks.

Around mid-April, Essex sheds its freezing nights — peas, lettuce, spinach, and radishes go into Essex's beds. Essex's heat-lovers — tomatoes, peppers, squash — hold off until Essex's frost risk clears, 10-14 days on. The season ends by mid-November in Essex, once hard frosts set back in. Essex's low ground holds frost later into spring than Essex's benches, which run 3-5 days ahead.

Similar climates: Middle River, MD, Bowleys Quarters, MD, Dundalk, MD, Rosedale, MD, Rossville, MD.
