What this ranking means
Tomatoes are frost-sensitive, popular, and heavily affected by seasonal heat. A city can have enough calendar days on paper but still be tight if spring starts late, summer heat is modest, or fall frost arrives before fruit has time to ripen.
Methodology
Scores use local GDD margin, frost-free season length, delay tolerance, and tomato variety flexibility.
Use this as a planning signal, not a guarantee. Microclimates, soil warmth, wind, irrigation, pests, and gardener skill can change real-world results.
