The 4 Seasons of the Year in Mexico and their Characteristics

The Seasons of the year in Mexico They occur in different parts of the territory with certain particularities in terms of temperature, duration, humidity and rainfall. In various places in Mexico you can see during the course of the year the seasons of spring, summer, autumn and winter.

In many places the climate does not vary much during the year and we usually talk about dry or humid climates, since the seasons are not very marked.

In general, it is estimated that spring arrives in Mexico from late March to late June, summer begins at the end of June and ends at the end of September, autumn occurs from late September to late December, and winter lasts from end of December to end of March.

The most important factors that influence the climate of Mexico and its seasons of the year are the geography of the territory, the presence of two oceans with which it borders, its location in the northern hemisphere of the earth and its proximity to the Caribbean region, among others.

In Mexico, high temperatures range between 30 and 40 °C, in spring and summer depending on the region of the country in which you are. For example, in the Federal District, it reaches an average of 17 °C due to height.

In regions to the north or south, the climate is completely different, since it is where they become more extreme, depending on the season of the year.

Spring (March 21-June 20)

Spring in Mexico presents relatively warm climates with temperatures close to 30 °C. It officially begins on March 21 of each year, succeeding the winter season. During the spring, various festivities related to this season are held.

The characteristic climate of spring is mostly dry as well as warm. However, Mexico has such a large territory that it favors changing temperatures.

Even at this time, low temperatures, rainfall, winds and even frosts can be appreciated.

The temperatures oscillate between 12 °C between the minimum and maximum of 30 °C. In general, the warmest temperatures are recorded in the middle of the season. The hours of the day are longer, so these can be used much more.

In May the weather turns dry to give way to the rainy season, which lasts until October.

Allergy season

During this season the plants begin to carry out the pollination process. Pollen is a very fine dust that can cause allergies in some people.

In this sense, its level in the air can vary due to the action of factors such as temperature and rainfall. People who are sensitive to pollen may develop allergy symptoms during this season.

Astronomical Events in the Spring

Total lunar eclipse known as the Blue Moon, at the end of March.
Lyrid meteor shower that will be visible in April.
Eta Aquarids meteor shower, brighter than the Lyrids, and which will be visible in May.
Opposition of Jupiter, which will cause it to appear closer to Earth and brighter in the night sky.

Summer (June 21-September 23)

Summer in Mexico officially begins on June 21 of each year and ends on September 23. It is a time of intense heat with temperatures reaching 38 °C in various areas of the country.

During this time there are occasional rains. It is a favorable season for tourism in the famous Mexican beaches.

It is the hottest season of the year and with the highest humidity, since it is marked by the rainy season that usually occurs in the afternoon. In this sense, once again the oscillation in temperatures is influenced by the region of the country.

To the north the high temperatures can become extreme, higher than 38 °C. This occurs in states such as Baja California, Sonora and Chihuahua.

Cooler areas with a greater presence of rain can be found in cities in the center and south of the territory, such as Mexico City, Oaxaca, Veracruz and among others.

Summer astronomical events

Saturn’s opposition to Earth will occur in June, so it will be seen closer and brighter in the sky.
The opposition of Mars to Earth, in the month of July.
Delta Aquarids meteor shower, a phenomenon that will last from the end of July to the end of August.
Partial solar eclipse, the second week of August.
Perseid meteor shower.
Neptune’s opposition to Earth at its closest distance, so a bright blue dot will be visible in the September sky.

Autumn (September 23-December 21)

It is the shortest season of the year in this country. The Mexican autumn is officially declared between September 23 and December 21.

It is characterized by favoring dry climates, however, at the beginning of autumn the rain increases due to the influence of tropical cyclones coming from both the Gulf of Mexico and the Pacific Ocean.

The reason why the weather is generally dry at this time is because the rainy season ends. However, some partial rains are not ruled out.

Usually the Mexican autumn is quite cool, with temperatures that drop towards the evening hours. The number of daylight hours is shortened and the day becomes as long as the night.

Astronomical Events in the Fall

Draconid meteor shower of low intensity during a few days in October.
Shower of stars known as Orionids, which will last for almost a month, from October to November.
Uranus opposition to Earth at the end of October. It will be visible throughout the night as a bright blue-green spot.
Leonids Meteor Shower in November.
Taurids Meteor Shower. They will meet twice, in September and December.

Winter (December 21-March 20)

It officially starts on December 21. The temperature during winter can reach a few degrees below zero in some regions of the country.

Despite the fact that the incidence of solar radiation during this season is significantly reduced, sunny days are still common and there is little rain.

During this season, temperatures vary depending on the region, which makes each winter seem different. It is characterized by low rainfall. This is because winter in Mexico coincides with the dry season, mostly in the south of the territory.

Temperatures in areas near the coast vary from warm to low at times. Factors like ocean temperature and water vapor affect temperatures.

In the central region, temperatures are quite low, especially in the morning and at night.

During this season the average temperatures fluctuate between minimums of 6 °C and maximums of 21 °C. In the middle of the season is when it is coldest. Frosts can be common due to the agglomeration of cold air.

Winter has the sunniest days in March, although with strong winds. 1967 was the year in which a snowfall occurred that covered 50% of the Mexican territory. In the Federal District, the snow reached heights of up to 60 cm in some areas of the historic center.

Astronomical events in winter

Meteor shower or Quadrantid stars.
The conjunction between Jupiter and Mars will occur: it will seem that they are very close in the sky.
