March–May and October–November give you the best mix of warm days, low rain, and manageable crowds. December is beautiful but busy and pricier around the holidays; June–September is lush and green but expect afternoon rain almost daily.
Mexico City doesn’t have a “bad” season the way a lot of destinations do — it sits at high altitude in a subtropical highland climate, so it’s mild almost year-round. What changes month to month is rain, crowds, and price, not whether you’ll be miserable.
Month-by-month cheat sheet
Broadly: December through February is the coolest, driest, clearest stretch, with chilly mornings that want a layer. March and April stay dry and bring the jacarandas into bloom, the city at its most photogenic. May is the warmest month, and the rains start to build. June through September is lush and green with an afternoon downpour most days, along with thinner crowds and lower prices. October and November dry out again with comfortable temperatures, plus Día de los Muertos at the start of November and the surge of visitors that comes with it.

The two seasons that matter
Dry season (roughly November–April). Blue skies, cool mornings, warm afternoons, next to no rain. This is peak tourist season, especially around the winter holidays and Semana Santa (the week before Easter), when the city empties out as residents travel and prices at hotels can swing either way depending on the neighborhood.
Rainy season (roughly May–October). Mornings are usually clear; rain tends to arrive in the afternoon or evening as a strong but short downpour, then clears up. The city is dramatically greener during these months, and jacaranda season (purple-blossomed trees) hits in March–April, just before the rains start — it’s one of the best times to see the city visually.
Events worth planning around
Weather and crowds are half the picture. These are the dates that move hotel prices and fill neighborhoods, whether or not you plan to join in.
- Jacaranda season (March–April). The purple-blossomed trees along Reforma, Roma, and Condesa peak here. It’s a visual thing, not a crowd or price driver. Read the story behind them.
- Semana Santa, Holy Week (dates move with Easter). Many small restaurants and shops close for part of the week as residents leave town. The trade-off is a quieter, more walkable center.
- Independence Day, Fiestas Patrias (September 15–16). The President reenacts El Grito from the National Palace balcony on the night of the 15th, and a military parade runs down Reforma the next morning. The Centro Histórico is packed, and hotels nearby fill for the weekend.
- Formula 1 Mexican Grand Prix (late October). Race weekend at the Autódromo Hermanos Rodríguez pushes hotel rates up city-wide, not just near the track, and it usually lands right before Día de Muertos. Book well ahead if your trip overlaps.
- Día de los Muertos (October 31–November 2). Altars, cemetery vigils, and a city-run parade down Reforma the Saturday before. The parade itself is recent: it didn’t exist until the 2015 Bond film Spectre opened with a fictional one, and the city built a real version afterward. One of the busiest, priciest weeks on the calendar.
- Guadalupe-Reyes (December 12–January 6). What locals call the run from the Virgen de Guadalupe feast day through Christmas, New Year’s, and Three Kings Day, with posadas, holiday markets, and lights on the Zócalo along the way. This is the busy, pricier December mentioned above.
If you’re coming for a specific reason
- Best weather overall: late October through early December, or March through early May.
- Avoiding crowds and paying less: June through September, accepting that you’ll get rained on most afternoons. What crowds there are skew Mexican families on summer break rather than international tourists.
- Avoiding altitude+heat combo: skip May if you’re sensitive to heat; it’s the one month that gets uncomfortably warm before the rain cools things off. Most shops, buses, and Airbnb rentals also don’t have air conditioning, since the stretch of the year that calls for it is short and infrequent enough that few places have bothered to install it.
Whatever month you land in, keep a light rain layer in your bag outside of the December–April stretch, and check the altitude guide before you go — the elevation affects how the weather feels more than the temperature number does.
