What "subtropical highland" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. San Miguel de Allende's type — subtropical highland — sits in the broad family of mild, temperate climates.
Researchers write climate types as a short letter code. Here is what each letter means:

Has San Miguel de Allende's climate type changed?

What this climate means for you
Coffee, avocado, flowers, citrus, temperate vegetables — all thrive at altitude. A long, gentle growing season.
Year-round travel weather; the dry winter is the cleanest, sunniest window for outdoor activity.
Often described as 'eternal spring' — mild days, cool nights, sunny dry winters. Heating is light; AC unnecessary.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from San Miguel de Allende's measured 30-year climate normals (1991–2020) — the same official records behind San Miguel de Allende's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
