The climate of Pico de Orizaba, like the Sierra Madre Oriental, varies greatly due to the change of elevation and prevailing winds.
Due to the latitude and the extreme rugged terrain the volcano experiences many microclimates.
Vegetation varies from tropical at the lower elevations on the eastern face to alpine forests in the higher elevations.

Large amounts of precipitation fall on the eastern face of the volcano due to adiabatic cooling and condensation from the trade winds that bring moisture off the Gulf of Mexico.
The eastern face is frequently covered by fog and low cloud cover.
The climate of the eastern face varies from tropical (Af) at the lower elevations to subtropical highland (Cwb) at the higher elevations, with mild variation in temperatures and an average annual rainfall of 1,600 mm (63 in).

Subtropical climates are found between 2,200–3,200 m (7,200–10,500 ft) above sea level with a regular rainfall all year long.
Autumn and winter come with frequent freezes and light snow, but the snow on the south and southeast sides melt quickly due to solar radiation.
The northern face is dominated by subtropical highland (Cwb).
The southern face mostly experiences humid subtropical climate Cfa which experiences the highest annual temperatures in the month of April.

Due to katabatic winds the western side is dominated by steppe (BSk) creating a rain shadow below 2,600 m (8,500 ft) above sea level.
Although there are some areas on the western side that experience (Cfa) most of the area is semi-dry with temperate to warm temperatures and an annual precipitation average of 550 mm (22 in).
Vegetation here is grass and shrubs with few alpine species.

Between 3,200–4,300 m (10,500–14,100 ft) where temperatures usually are between 2 to 5 °C (36 to 41 °F), continental subarctic climate (Dfc) predominates.
Over 4,300 m (14,100 ft) with an annual average low of −2 °C (28 °F), alpine tundra (ET) prevails to the summit; heavy snowfalls and blizzards are common throughout the year.
Snow on the south and southeast melts due to solar radiation, but continually remains on the north and northwestern faces.
Extreme cold dominates a surface area of approximately 31 km² (12 sq mi).
