Temperature in Mexico City in October
The 10°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. At 78% humidity, the 20°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. UV index averages 6 this month, classed as moderate. Sunscreen is a sensible precaution for extended outdoor time, particularly at midday. Winds are calm at an average 13 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 68°F average high, 50°F overnight low.

What to Wear in Mexico City in October
Packing for Mexico City in October means dressing for 20°C days and 10°C evenings. A light cotton tee with a casual overshirt works well at 20°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 10°C, a modest 10°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. With 14 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes. At 78% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Layers are more practical than a single heavy garment in Mexico City. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
