#Weather in Mexico City in September
Mexico City in September averages 13–24°C (55–75°F) with around 18 days of rain, and crowds are medium.
| Measure | September |
|---|---|
| Daytime high | 24°C / 75°F |
| Overnight low | 13°C / 55°F |
| Rain | 18 wet days, 158mm |
| Pattern | The afternoon storm, beginning to loosen its grip late in the month |
September is the last full month of the rains and the first in which they start to relent. Eighteen wet days against July's twenty-two, and the storms become less reliable towards the end — which is a loss rather than a gain if you have learned to plan around them.
It is also the most Mexican month of the Mexico City year. The whole of September is mes patrio, the patriotic month: flags go up on buildings across the city from the first week, green-white-red lighting appears on the Zócalo, and the independence season runs to the 16th.
#What to Do in Mexico City in September
El Grito (the night of 15 September)
The largest civic night of the year. The president rings the bell from the balcony of the National Palace late on the 15th, repeating the call to independence, and the Zócalo fills with tens of thousands of people. A military parade follows on the morning of the 16th along Reforma and through the square.
The dates are fixed by law and do not move. Hotels near the Centro book out well in advance, and the square is closed to traffic for days on either side.
⚠️ Go early if you want to be in the Zócalo itself, and go understanding that this is a national celebration rather than an event staged for visitors.
Chiles en nogada
In season and everywhere, from market fondas to the tasting restaurants. This is the month for them.
The last of the green
The valley is still at its wet-season best in early September and starts to turn by the end of it.
Museums, unchanged
Antropología, Bellas Artes, the Museo Nacional de Arte. Still the afternoon answer while the storms hold.
#Getting Around
Wet-season rules still apply through most of the month: mornings for crossing the city, afternoons for staying put, flooding in low-lying stations during a serious storm.
⚠️ The Centro is closed to traffic for days around the 15th and 16th, and the Zócalo is inaccessible by car well before that. Plan to arrive on foot or by Metro, and expect stations near the square to be exceptionally busy on the night of the 15th.
Altitude still applies on arrival.
#Budget & Costs
September splits sharply.
The week around the 15th and 16th prices like a peak in the Centro and anywhere within reach of it, and hotels book out early. The rest of the month, particularly the first ten days, is still inside the value stretch that ran through the summer.
Hotels carry a lodging tax on top of the room rate and 16% value-added tax applies broadly. ⚠️ Confirm the current rate at booking.
Tipping runs 10 to 15% and is not usually included.
#Food & Dining
September belongs to chiles en nogada — poblano chillies stuffed with a sweet and savoury picadillo, covered in walnut cream and scattered with pomegranate, in the green, white and red of the flag. They are seasonal, they are tied to the independence month, and versions range from a market fonda's to a tasting menu's.
Pozole is the other September dish, particularly around the 15th and 16th — a hominy soup, white, green or red, eaten late and in company.
The comida corrida habit still works, and September is the last month in which a storm will reliably justify it.
Tap water is not drunk here; bottled and filtered is universal.
#Nightlife
The 15th is the biggest night out of the Mexican year and it is not confined to the Zócalo — bars, restaurants and private parties across Roma, Condesa and the Centro all run their own grito at eleven.
The rest of the month is ordinary and pleasant: warm evenings, rain mostly finished by the time the city goes out.
⚠️ Altitude amplifies alcohol, and the 15th is not the night to discover that.
#Shopping
Flags, and an enormous quantity of them. Street vendors sell tricolour everything from the first week, and the markets around the Centro are the place for it.
Mercado de Jamaica for flowers, Mercado de la Ciudadela for craft, and the covered markets generally while the rains hold.
#Culture & Etiquette
⚠️ The 15th and 16th are participatory, not a spectacle. Shouting along with the grito, wearing the colours and joining the crowd are all welcome. Standing at the edge photographing it as though it were a performance is the wrong posture, and the difference is noticed.
⚠️ The 19th of September is a solemn date, not a festive one. Major earthquakes struck the city on that date in both 1985 and 2017, and a national drill is held every year on the anniversary. Sirens sound across the city and buildings evacuate. It is not a test failure if you are caught in it — follow your hotel's marked assembly point.
#Essential Local Phrases
| Spanish | What it means |
|---|---|
| El Grito | The cry of independence, called from the balcony on 15 September |
| ¡Viva México! | The response, shouted back by the whole square |
| Mes patrio | The patriotic month — all of September |
| Chiles en nogada | The September dish, in the colours of the flag |
| Simulacro | The earthquake drill, held every 19 September |
| La cuenta, por favor | The bill, please — it will not arrive unrequested |
| Colonia | The neighbourhood — addresses are given by colonia, not district number |
#Packing List
- A compact umbrella; the rains are still running for most of the month
- Shoes that cope with standing water and with standing for hours on the 15th
- Something in green, white or red if you intend to join in, which is normal rather than costume
- A layer for the evening
- Sunscreen for clear mornings
- A dry pouch for a phone
- A small bag rather than a large one for the Zócalo crowd
- Cash in small notes
#Safety & Health
Air quality is still good, though the improvement starts to fade as the rains do.
⚠️ The 19 September drill is annual and citywide. Sirens, evacuations and assembly points. Know where your hotel's is on arrival rather than finding out during it.
Flooding and lightning remain the seasonal hazards through most of the month.
Crowds are the September-specific risk. The Zócalo on the night of the 15th holds a very large number of people; keep valuables out of sight, agree a meeting point with anyone you are with, and expect phone signal to fail.
Altitude is unchanged. Slow first day.
#Backup Plans
- Museums close on Monday, and government buildings close on the 16th.
- If the Zócalo is too full to enter on the night of the 15th, neighbourhood plazas across the city hold their own grito and are far easier to be in.
- The Centro museum cluster still absorbs a wet afternoon.
- If a storm cancels a morning plan in early September, the following morning will usually be clear.
- Restaurants fill for chiles en nogada on the weekends around the 16th. Book, or eat in a market.
