How this map works

Every 28 km square of land is scored 0–100 against the requirements above, using 1991–2020 monthly climate averages with frost, chill and heat estimated by simulating daily weather. Each square is scored with whichever variety fits it best. “With irrigation” ignores rain shortfalls; “Rain-fed only” counts them.

Climate is only part of it: soil, slope, water and markets decide where a crop is actually farmed. Use this to shortlist places, then check them locally.
