Mexico City’s climate is shaped by its altitude (2,240 metres above sea level), resulting in mild, spring-like temperatures throughout the year. The city experiences two main seasons: a dry season from November to April and a wet season from May to October. During the dry season, days are sunny and warm, with average highs of 21–27°C, while nights can be chilly, sometimes dropping to 5–8°C, especially in December and January. Sunshine is most plentiful from February to April, with up to 8 hours per day, though mornings and evenings may feel brisk due to the thin mountain air.
The wet season brings frequent afternoon and evening showers, peaking from June to September. July and August are the rainiest months, with monthly rainfall reaching 150–160 mm and up to 17 rainy days. Despite the rain, mornings are often clear, and temperatures remain comfortable, with highs around 23–25°C and milder nights. Rain showers are typically brief but can be heavy, sometimes accompanied by thunder or hail. The city receives about 2,500–2,600 hours of sunshine annually, though cloud cover increases in the rainy season. Snow is extremely rare in the city itself, but surrounding mountains may see occasional snowfall. Winds are generally light, but pollution and haze can affect visibility, especially in winter and spring.
Mexico City’s weather is generally predictable and pleasant, but travellers should prepare for notable temperature swings between day and night, and for sudden downpours during the rainy months. The high UV index year-round means sun protection is always advisable.
