What's in season at US farmers markets

How the calendar works

Each state is mapped to one of 6 US climate zones based on USDA growing data: Deep South, Mid-South & coastal CA, Mid-Atlantic & coastal PNW, Midwest & Northeast, Upper North & Alaska, and Mountain West / Desert SW. The zone determines the typical month-by-month produce pattern.

On top of the zone baseline, each state has its own signature crops — Palisade peaches for Colorado, wild blueberries for Maine, Jersey tomatoes for New Jersey, Hatch chiles for New Mexico — that get featured in their peak months. Local microclimates and individual growers (hoop houses, season extension) shift these by 2-4 weeks in either direction. Always ask your farmer what just came in.
