How these scores work
Each crop has an ideal range and hard limits for things like winter cold, chill hours, summer heat and rain. A score of 100 means everything is in range; one hard limit crossed means 0. Annual crops are scored over their best growing season, which sets the planting month. Scores assume irrigation where rain falls short, and flag crops that need it.
Climate comes from 1991–2020 monthly averages for the 4 km climate cell around the town. Frost dates, chill and hardiness zones are estimated from those averages by simulating daily weather, so check them against local records. Soil, slope and water rights matter as much as climate. Crop ranges come from FAO ECOCROP and university extension guides and haven't been reviewed by an agronomist yet.
