Best time to visit Mexico City

A capital with two seasons, not four

Mexico City sits at 2,240 metres in a high valley, and that altitude does something unusual to its calendar: the temperature barely moves all year. Afternoon highs hover between 22°C and 28°C in every month, and mornings stay cool. What actually changes — and what decides the best time to come — is rainfall and the clarity of the air. The year splits cleanly into a long, sunny dry season (roughly November to April) and a green, stormy rainy season (June to September). For most travellers, the dry months are the sweet spot.

The best months: March, April and May

April is the standout month.It is the year's warmest and sunniest, with highs near 28°C, around twelve hours of daylight, and still-low rainfall of about 19mm before the wet season breaks. March matches it almost exactly — equally warm and dry — and May keeps the warmth while the very first afternoon showers begin to appear late in the month. This March-to-May stretch is the brightest, driest-air window of the year, made for sidewalk cafés, rooftop terraces, plaza-hopping and day trips out to the Teotihuacán pyramids.

Spring's headline act: the jacaranda bloom

There is a reason spring tops so many shortlists. For a few weeks across March and into early April, thousands of jacaranda trees erupt in lilac-purple blossom, lining the avenues of Roma, Condesa and San Ángel and dusting whole plazas in colour. The bloom lands squarely in the warmest, driest stretch of the year, so the prettiest scenery arrives with the most reliable weather. It is, by a wide margin, the most photogenic window to visit — and it coincides with the Festival de México, which fills the historic centre with music, dance and theatre across March.

The other prime window: November and December

The dry season's far edge is just as rewarding. November returns to classic clear-sky conditions after the rains retreat — around 10mm of rain, warm afternoons near 24°C and crisp mornings — and it is one of the best all-round months on the calendar: bright, comfortable and relatively uncrowded once the Día de Muertos spike has passed. December is cooler and equally dry, with festive energy from Christmas markets, posadas and the Guadalupe pilgrimages. Both months deliver the postcard version of the city, though they bring the largest day-to-night temperature swings of the year.

If you come for Día de Muertos, plan early

Mexico City's signature celebration, Día de Muertos (October 31 to November 2), is unforgettable: marigold altars, painted faces and a grand parade down Reforma. It also lands right as the dry season returns, so the weather is usually excellent. The catch is demand — these few days are the single biggest spike of the year, when flights and hotels fill and prices climb. If the Day of the Dead is your reason to come, book flights and rooms months ahead and accept that you are travelling at the busiest moment on the city's calendar.

Why even the rainy season works for many travellers

Do not write off June to September. The rainy-season pattern here is unusually forgiving: mornings open bright and warm, clouds build through the day, and a heavy thunderstorm rolls in during the late afternoon or evening, often clearing by night. As long as you front-load sightseeing into the mornings, plenty of trips run smoothly — and the city is at its lush, green best, with lower prices to match. September adds the patriotic energy of Independence Day around the Zócalo. The trade is simply reliability: you cannot count on a dry afternoon the way you can in April.

One thing to plan for: the altitude

Whatever month you choose, respect the 2,240-metre elevation. Some visitors feel short of breath, headachy or tired on arrival as their body adjusts to the thinner air. The fix is simple: take your first day easy, skip strenuous hikes or long climbs at first, drink plenty of water and go gently on alcohol until you have acclimatised. The thin air also lets the sun bite harder than the mild temperatures suggest, so wear sunscreen even on cool, cloudy-looking days.

The short answer

For the best blend of warm, sunny days and dry afternoons, target March through May — and aim for the jacaranda weeks of late March if you want the city at its most beautiful. November and December are the excellent cool-and-clear alternative. The June–September rains are no deal-breaker for morning-focused travellers chasing lower prices and green parks. To see how the city stacks up against the rest of the country, compare it with the best time to visit Mexico or the beach-season rhythm of Cancun, or place it against every destination on the Best Time to Travel leaderboard.
