Mexico City weather month by month
What is the weather like in Mexico City each month?
Mexico City has two clear seasons: dry (November–May) with 10–25°C days and reliable sunshine, and rainy (June–October) with warm mornings and afternoon thunderstorms averaging 1–2 hours. The altitude of 2,240 m keeps temperatures mild year-round — it never gets truly hot or truly cold by global standards.
Understanding Mexico City’s climate at 2,240 m
Mexico City’s weather is shaped primarily by altitude, not latitude. At 2,240 m (7,350 ft) on a broad highland plateau — the Valley of Mexico — the city never gets the tropical heat of coastal destinations like Cancún or Puerto Vallarta. But it also never gets the true cold of mountain resorts. The result is a remarkably stable temperature band year-round: 10–25°C covers almost every day of every month.
What changes dramatically between seasons is rainfall. The Inter-Tropical Convergence Zone brings moisture from the Pacific and Gulf of Mexico through the highlands from June through October, producing the city’s characteristic afternoon thunderstorms. From November through May, this moisture source retreats and the city enjoys almost unbroken sunshine.
UV radiation deserves a separate mention. At 2,240 m, you receive roughly 25% more UV radiation than at sea level for the same cloud conditions. Sunscreen is essential year-round, not just in summer.
January
Temperature: 7–21°C (average low 7°C, average high 21°C) Rainfall: ~5 mm (one of the driest months) Sunshine: ~7–8 hours/day
January is cold by local standards but mild by global ones. Morning temperatures around 7–9°C require a real jacket. By midday it typically climbs to a pleasant 18–21°C. Rain is extremely rare. The city is post-holiday but still somewhat festive through Three Kings Day (January 6), when families exchange final Christmas gifts and the street bakeries make a ring-shaped Rosca de Reyes cake.
Practical note: some smaller restaurants and shops take vacation between Christmas and January 8–10. Museum attendance is back to normal after the holiday peak.
February
Temperature: 8–23°C Rainfall: ~5 mm Sunshine: ~8 hours/day
February is dry, often sunny, and warming slightly toward spring. Daytime temperatures regularly hit 22–24°C by mid-month. The city is quieter than March–April — a good window to visit without peak-season crowds. Valentine’s Day brings out restaurants in Roma and Condesa — book ahead for nicer spots.
The Zócalo often hosts cultural events and temporary art installations through February. The Palacio de Bellas Artes programming picks up after the quiet post-Christmas period.
March
Temperature: 10–25°C Rainfall: ~10 mm Sunshine: ~8 hours/day
March is when the magic happens: the jacaranda bloom begins in earnest from mid-March, with purple-blue flowers coating the trees along Avenida Amsterdam in Condesa, the streets of Coyoacán, Avenida Insurgentes, and the UNAM campus. The jacaranda guide covers exact spots and timing.
Temperatures are ideal — warm enough for t-shirts by midday but fresh in the morning. The Spring Equinox (around March 21) brings large crowds to Teotihuacán for the traditional gathering in white clothing. This is peak tourist season; hotel prices are at their highest.
April
Temperature: 12–26°C Rainfall: ~20 mm Sunshine: ~7–8 hours/day
April continues the jacaranda season into its final weeks. Temperatures are the warmest of the dry season — 24–26°C at midday. Easter week (Semana Santa) falls in March or April depending on the year and is Mexico’s main domestic holiday period. Museums, parks, and transport are busy with local families. Pre-booking accommodation and popular tours is essential.
The first tentative afternoon showers can appear in late April, signalling the transition. These are not yet the established rainy season pattern — more isolated events that are easy to work around.
May
Temperature: 14–26°C Rainfall: ~50 mm Sunshine: ~6–7 hours/day
May is warm and increasingly humid as the rainy season approaches. Afternoon cloud builds through the month, and from mid-May, some days see genuine afternoon showers. By late May the rainy season is effectively beginning. Daytime temperatures are warm (24–26°C) and evenings are pleasant.
May 5 (Cinco de Mayo) is a public holiday commemorating the 1862 Battle of Puebla. It is celebrated modestly in Mexico City itself — primarily a state occasion — though the Puebla and Cholula day trip around this date has particular historical resonance.
June
Temperature: 13–24°C Rainfall: ~120 mm Sunshine: ~5–6 hours/day
June marks the firm establishment of the rainy season. The afternoon thunderstorm pattern becomes reliable: mornings are sunny and warm (20–23°C), clouds build through lunch, and rain typically arrives between 3:00 and 6:00 pm. The storms can be intense — genuine downpours with thunder — but usually pass within 1–2 hours.
Hotel prices drop from May–June, and international tourist numbers are lower. The city’s parks and gardens are at their greenest. A street food tour of Mexico City’s historic downtown is particularly good in the morning before the afternoon rain; the markets are at their freshest early in the day.
July
Temperature: 13–22°C Rainfall: ~170 mm (wettest month) Sunshine: ~4–5 hours/day
July is the wettest month. Rainfall averages 170–180 mm spread across 20+ rainy days. Some days see prolonged rain; most follow the morning-sun, afternoon-storm pattern. Temperatures are actually very comfortable — the rain cools things down to 17–20°C during storms.
This is a good month for museums. The National Museum of Anthropology near Chapultepec and Polanco is never more enjoyable than when you duck in from the rain and find the galleries relatively quiet. The Frida Kahlo Museum in Coyoacán has shorter queues than spring — advance booking is still advisable but less critical.
August
Temperature: 13–22°C Rainfall: ~150 mm Sunshine: ~4–5 hours/day
August is similar to July — wet afternoons, comfortable temperatures. Mexican school holidays mean local families are out in force at parks and family-oriented attractions (Xochimilco, Chapultepec Zoo). International tourist numbers remain lower than in the dry season.
One practical note: air quality in Mexico City sometimes improves noticeably in the rainy season as precipitation washes particulates from the air. The city can look genuinely crisp and clean after a good August thunderstorm.
September
Temperature: 12–22°C Rainfall: ~130 mm Sunshine: ~4–5 hours/day
September brings Mexico’s most significant patriotic moment: El Grito de Independencia on the night of September 15. The President re-enacts Miguel Hidalgo’s 1810 call to arms from the balcony of the National Palace on the Zócalo. Hundreds of thousands gather in the main square for a raucous, festive celebration. Book accommodation and plan transport well in advance — Uber/DiDi prices surge and metro stations near Centro get extremely crowded.
Weather is still rainy but temperatures begin to ease slightly. Late September sometimes sees a transition toward drier conditions.
October
Temperature: 10–22°C Rainfall: ~60 mm Sunshine: ~5–6 hours/day
October is the transition out of the rainy season. Rainfall diminishes noticeably from September, and by late October some days are fully dry. Temperatures cool slightly — 18–22°C by day, 10–12°C at night. The city shifts its mood toward the approaching Día de Muertos: bakeries stock pan de muerto, marigold (cempasúchil) flowers appear in markets, and ofrenda displays start going up in shop windows and public spaces.
October is an underrated month to visit — lower prices than November, good weather improving through the month, and the Día de Muertos buildup adding cultural texture without the peak-November crowds.
November
Temperature: 8–22°C Rainfall: ~15 mm Sunshine: ~7–8 hours/day
The dry season is fully re-established by November. Rainfall is minimal, skies are clear, and daytime temperatures hover at a very pleasant 20–22°C. November 1–2 (Día de Muertos) is the year’s most culturally significant event: elaborate altars across the city, the Mixquic night ceremony south of CDMX, and Xochimilco’s decorated canal tours. See the Xochimilco complete guide for the Día de Muertos trajinera experience.
Hotel prices spike around November 1–2 and recover quickly after. The rest of November is excellent value — dry, sunny, and less crowded than December.
December
Temperature: 5–20°C Rainfall: ~8 mm Sunshine: ~7–8 hours/day
December is cold by Mexico City standards. Morning temperatures often fall below 7°C in the first and last weeks, with the coldest nights of the year around Christmas. Daytime highs of 18–20°C are pleasant but cooler than any other dry-season month. Pack warm layers for mornings and evenings — a light down jacket is ideal.
The city is beautifully decorated. Posadas processions (the nine-night pre-Christmas tradition recreating Mary and Joseph’s search for shelter) run December 16–24 in residential streets across Roma, Condesa, and Coyoacán. Street food stalls multiply around the Centro, selling hot atole, tamales, and ponche (a warm spiced fruit punch). December 12 brings pilgrims from across Mexico to the Basilica de Guadalupe — one of the most visited Catholic shrines in the world.

Frequently asked questions about Mexico City weather month by month
What is the average temperature in Mexico City in winter?
December through February: daytime highs of 18–22°C, overnight lows of 5–9°C. Genuinely cold by local standards for mornings and evenings; a winter jacket is necessary, not optional.
Does Mexico City have a spring season?
March and April feel spring-like — warming temperatures, low rainfall, and the famous jacaranda bloom give the city a distinctly vernal character. This is when Mexico City is at its most photogenic.
Is Mexico City humid?
Not particularly. The dry season is low humidity, which makes the altitude-moderated temperatures very comfortable. The rainy season brings higher humidity before afternoon storms, but the city does not have the oppressive humidity of tropical coastal areas.
Can I visit Mexico City year-round?
Yes. Every month offers a functional, enjoyable visit. Weather is the main variable — choose dry season for reliable sunshine, rainy season for lower prices and a more local pace. See the best time to visit guide for a decision-making framework.
How should I dress for the altitude in Mexico City?
Layers are the answer year-round. At 2,240 m, temperature shifts between morning (cold) and midday (warm) are larger than at sea level — a difference of 10–15°C between sunrise and noon is normal. Start every day with a jacket you can peel off by 10 am. Read the altitude guide for the physical effects of 2,240 m on your body.
