Weather in Mexico in July: What to Expect?
The rainy season: When does it start and how long does it last?
The rainy season in Mexico generally begins in June and lasts until the end of October , although in some tropical regions it can begin as early as May. July , in particular, represents the month with the greatest rainfall accumulation, especially in the center and south of the country. This climatic phase is influenced by various atmospheric systems, such as tropical waves that cross the country from the Caribbean, cyclones from both the Pacific and Atlantic Oceans, and lingering cold fronts that affect the north.
The combination of these phenomena causes almost daily rainfall, often accompanied by thunderstorms, gusty winds, and occasionally hail. These weather conditions can be dangerous if proper precautions are not taken.
Temperatures by region
| Region | Average temperature | Characteristics |
|---|---|---|
| North | 30-40 °C | Dry heat, occasional rain and isolated thunderstorms |
| Center | 20-28 °C | Almost daily afternoon showers, cool mornings |
| South and southeast | 25-32 °C | High humidity, heavy rains, tropical climate |
| Coasts | 28-34 °C | Humid heat, risk of storms or tropical cyclones |
Regions with the greatest impact of rainfall in July
Mexico City and downtown
During the month of July, Mexico City and its metropolitan area experience frequent rainfall, mainly in the afternoon or evening. These rains are often accompanied by thunder, lightning, and even hail in certain areas of the Valley of Mexico. The impact on mobility is significant, with flooding, road closures, and public transportation delays.
At home, it's common for many homes to experience leaks or electrical failures if they haven't been properly prepared. Therefore, in this region, it's essential to always carry an umbrella, wear appropriate footwear, and check the weather forecast before going out.
Southeastern states: Chiapas, Oaxaca, Tabasco
The southeastern Mexican states of Chiapas , Oaxaca, and Tabasco experience some of the country's highest rainfall in July. These downpours, which can last for several hours, cause rivers and streams to swell, increasing the risk of flooding and landslides in hilly communities or rural areas.
In agricultural areas, these rains can be beneficial, but they also affect roads, cause power outages, and hinder mobility between communities. In this regard, having evacuation plans and temporary shelters can be key in vulnerable areas.
Yucatan Peninsula
On the Yucatán Peninsula , which includes the states of Campeche, Yucatán, and Quintana Roo, July rains are intense but generally concentrated in the afternoons. Mornings are usually warm and sunny, allowing for relatively normal tourist activities if precautions are taken.
However, due to the tropical climate, humidity is high, and there is a constant watch for possible tropical cyclones . Tourist destinations such as Cancún, Tulum, and Mérida may be affected by sudden downpours, so it is recommended to monitor local weather alerts.
Common risks during July in Mexico
During the month of July, rainy weather in Mexico can lead to several risks for the population, especially in urban and rural areas with poor or exposed infrastructure:

Landslides : mainly on mountain roads or in hillside communities.
Increase in mosquito-borne diseases such as dengue, Zika, and chikungunya due to stagnant water.
