Las cuatro fechas que importan
| Fecha | Cuándo | Qué significa |
|---|---|---|
| Última helada de primavera (50 %) | Apr 29 | La mitad de los años hiela después de esta fecha. Es una media, no una garantía. |
| Última helada de primavera (10 %) | May 11 | Solo un año de cada diez hiela después de esta fecha. Úsala para lo que no puedas permitirte replantar. |
| Primera helada de otoño (50 %) | Oct 15 | La mitad de los años hiela antes de esta fecha. Los cultivos de otoño se cuentan hacia atrás desde aquí. |
| Primera helada de otoño (10 %) | Oct 2 | Un año de helada temprana. Si un cultivo tiene que terminar, apunta a cosechar antes de esta fecha. |
Siembra de primavera y verano en Burlington
Las fechas se calculan con la última helada de este lugar, no con una tabla genérica por zona. Los «mejores días lunares» son los días de cada ventana que caen en la fase tradicional del cultivo, la misma regla que usa la app.

Siembra de otoño en Burlington
Las fechas de otoño se cuentan hacia atrás desde la primera helada y añaden tiempo por el «factor de otoño»: los días se acortan y refrescan, así que el cultivo crece más despacio de lo que promete el sobre. Sembrar tarde es la forma más común de que falle un huerto de otoño.

De dónde salen estos números
Las fechas de helada de esta página son normales observadas en estación, no estimaciones: vienen de Burlington Intl Ap (GHCN USW00014742), una de las 6.808 estaciones de EE. UU. de las Climate Normals 1991–2020 de la NOAA. La zona de rusticidad es del USDA Plant Hardiness Zone Map de 2023. Los tiempos de cultivo se expresan como desfases respecto a tus heladas, tomados de guías de siembra de la Extensión universitaria.
¿Qué precisión tiene todo esto?
Extension recommendations for the same crop routinely disagree by two to four weeks, and occasionally more, so these offsets should be presented as windows and starting points rather than deadlines. Three things drive the spread. (1) Regional risk tolerance: for warm-season crops, Colorado State and Utah State put tomatoes, peppers and melons out about 14 days after the last frost, while University of Missouri's calendar works out to roughly 25-35 days after the last frost and University of Maryland's window runs from the frost date itself out to 45 days past it. That is a real 6-week spread for the single most popular garden crop, and it exists because a short-season mountain state is optimizing against a short season while a humid continental state is optimizing against cold, wet spring soil. (2) Soil temperature versus calendar date: most Extension services now say the honest trigger is soil temperature at 4 inches, not the frost date, and the frost-relative number is a convenience translation. A cold, wet spring can push the real date two or three weeks past the calendar recommendation. (3) Days-to-maturity is variety-specific and is measured differently for direct-seeded versus transplanted crops - seed catalogs count from transplant date for tomatoes, peppers, eggplant and cole crops, but from sowing for roots and greens - so a 'days to maturity' range of 60-85 for tomato is genuinely 60-85 depending on which packet you bought. Additionally, the average last frost is a 50% probability, meaning half of all years have a frost after that date; Extension services commonly advise waiting 1-2 weeks past it for anything frost-tender, or being prepared to cover. Treat every number here as plus or minus about 10-14 days.
Sobre la estación en sí: una estación meteorológica es un punto. Las ciudades retienen el calor, los valles acumulan aire frío y un huerto en ladera norte puede ir dos semanas por detrás de otro a una milla. Toma esta página como punto de partida y deja que tu propio huerto la corrija: para eso está el diario de la app.
