Köppen climate classification
The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are "A" (tropical), "B" (dry), "C" (temperate), "D" (continental), and "E" (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the "E" group are assigned a seasonal precipitation subgroup (the second letter). For example, "Af" indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the "A" group, indicated by the third letter for climates in "B", "C", and "D", and the second letter for climates in "E". For example, "Cfb" indicates an oceanic climate with warm summers as indicated by the ending "b". Climates are classified based on specific criteria unique to each climate type.
Milpa Alta
Most of the area has a temperate climate, with cold climates found at the highest elevations. The average annual temperature is with average lows at and averages highs at . Average annual precipitation is . Freezing temperatures occur occasionally from October to March especially in the higher elevations. The windiest months are February and March. On the Koppen scale, its climate is described as C (W2) (w) b (i’) which signified a relatively moist climate, with a rainy season in the summer especially in July and August. However, the climate varies substantially in the territory based mostly on altitude, with six sub-climates: C(E)(w2) which is relatively cold, C(E)(m) also relatively cold but wetter, C(w1) a temperate climate, C (w2) a températe and relatively wet climate, C ( w1) temperate and relatively dry and C ( w2) which is relatively cold with rains falling mostly in the highest areas.
