October is Mexico’s turning point. The rains end, the country is still green from five months of them, the Caribbean water clears as the sargassum season closes, and the whole month builds towards Día de Muertos on 1 and 2 November. It is also the last cheap month before the winter season begins – and one of the best-value months in the Mexican year.
The rains end
Through October the wet season winds down across most of the country. Mexico City falls from roughly 145 mm in September to about 75 mm, and by the last week the afternoon storms have largely stopped. The landscape stays green for weeks afterwards, which is the specific pleasure of October: dry-season weather over wet-season scenery.
The exception is the Yucatán and the Caribbean coast, which stay wetter into November and remain inside hurricane season – October is the last genuinely active month before the season closes on 30 November.
Weather by region
- Mexico City and the central highlands – around 24°C by day and 11°C at night, with roughly 75 mm of rain and falling. Bright, green and comfortable; the nights start to get cold.
- Oaxaca – drying out, green, warm by day and cool at night. One of the best months there.
- The Yucatán and Caribbean – around 30°C, still humid, with roughly 155 mm and the last of the hurricane risk. The water starts clearing as sargassum declines.
- The Pacific coast – the rains taper through the month; by late October, Puerto Vallarta and the Oaxacan beaches are entering their season.
- Baja California – warm, dry and excellent; the Sea of Cortez is at its best for diving.
The build to Día de Muertos
Day of the Dead falls on 1 and 2 November, but October is when it is assembled. From about the middle of the month:
- Markets fill with cempasúchil (marigolds), sugar skulls, papel picado and pan de muerto.
- Ofrendas appear in homes, shops, museums and public squares.
- Oaxaca and Pátzcuaro book out. These are the two great centres of the observance, and accommodation for late October and early November is reserved months ahead at multiplied rates.
- Mexico City’s parade, a modern invention rather than a traditional one, is usually held on a Saturday in late October or the start of November, with the date announced by the city government.
If you want Day of the Dead in Oaxaca or Michoacán, book in spring, not autumn. If you are flexible, almost any Mexican town holds a genuine, uncrowded observance of its own.
Cervantino, and the rest of October
The Festival Internacional Cervantino in Guanajuato runs for roughly three weeks in October and is the largest arts festival in Latin America – theatre, opera, dance and music in plazas and colonial theatres across the city. Guanajuato is small and fills completely; book well ahead.
October also brings the start of the monarch butterfly migration into Michoacán and the State of Mexico, though the sanctuaries usually open to visitors in November.
What October is good for
- Value. The last month before winter pricing, with the weather already good.
- The highlands. Mexico City, Puebla, Oaxaca, Guanajuato and San Miguel de Allende are at their best.
- Clearing water. Sargassum declines through the month and Caribbean visibility improves.
- Turtle hatchlings, which continue on both coasts.
- Atmosphere, as the Day of the Dead preparations take over.
Prices and crowds
Low until about the 25th, then sharply higher in the Day of the Dead destinations. Elsewhere – the Pacific coast, Baja, the colonial interior outside Guanajuato – October stays inexpensive right to the end of the month.

What to pack
Layers. October days are warm and highland nights drop to around 11°C, which is genuinely cool at altitude. Keep a light rain shell for the first half of the month, sun protection throughout, and something smart if you are going to Cervantino performances. See the Mexico packing list.

Frequently asked
Is October a good time to visit Mexico?
One of the best. The rains end while the landscape stays green, the Caribbean water clears, prices remain low until the last week, and the whole country builds towards Day of the Dead.
Is it still rainy season in October?
It is ending. Mexico City drops to roughly 75 mm and by the last week the afternoon storms have largely stopped. The Yucatán and Caribbean coast stay wetter and remain inside hurricane season.
When is Day of the Dead?
1 and 2 November, with 2 November the public holiday. October is when it is prepared, and accommodation in Oaxaca and Pátzcuaro for late October and early November sells out months in advance.
Should I book Oaxaca for Day of the Dead in October?
Book it in spring, not October. Oaxaca and Pátzcuaro are the two great centres and both fill months ahead at multiplied rates. Any Mexican town holds its own genuine observance if you are flexible.
Is there still sargassum in October?
It declines through the month as the season closes, and Caribbean visibility improves steadily. November to February is the reliably clear window.
What is the Cervantino festival?
The Festival Internacional Cervantino in Guanajuato, the largest arts festival in Latin America, running for about three weeks each October across the city’s plazas and colonial theatres. Guanajuato is small and fills completely.
Is October hurricane season in Mexico?
Yes, it is the last genuinely active month; the season closes on 30 November. Risk is lower than September but not negligible on the Yucatán and Pacific coasts.
Is Mexico cheap in October?
Until about the 25th, yes – it is the last inexpensive month before winter pricing. After that, rates spike in the Day of the Dead destinations but stay low elsewhere.
