Ecatepec de Morelos, located in Mexico, is characterized by an arid climate with moderate temperatures and extremely low annual rainfall. Despite this, the year can be divided into two main seasons based on precipitation levels and the frequency of rainy days, while the temperature remains relatively comfortable throughout.

The dry season typically lasts from November to April, sometimes extending into May. During this time, Ecatepec de Morelos enjoys plenty of sunshine, and precipitation is practically non-existent, especially from December to March when rainfall levels drop toward zero. Daytime temperatures during this period range from a pleasant +21°C in winter to a warmer +27°C by late spring. Nights, particularly in the winter months, can be quite chilly, with temperatures dipping to +6°C – +10°C.

The period from June to September or October is considered wetter, although total rainfall remains very low. Daytime temperatures during these months usually stay between +22°C and +25°C. The main feature of this period is a noticeable increase in the number of days with precipitation; however, the rain itself is usually very light or a fine drizzle. For example, in July and August—the peak of this season—there may be up to 24–25 rainy days, yet the total monthly accumulation does not exceed 5 mm.

In Ecatepec de Morelos, the temperature regime is fairly stable throughout the year, though it features noticeable seasonal variations. The hottest month is typically May, with an average temperature of 19.7°C and daytime highs reaching 27.1°C. March and April follow closely, offering warm weather with maximum temperatures ranging from +26.4°C to +26.8°C. The coolest months are January and December, with an average temperature of around 13.8°C. During these winter months, nighttime temperatures can drop to 6.5°C – 6.8°C, creating a distinct chill.

The summer period, roughly from May to September, is characterized by warm weather. In May, daytime temperatures are at their highest, reaching +27.1°C. From June to September, average daytime temperatures decrease slightly, ranging between +21.9°C and +24.7°C, while nights remain mild with minimums around +12°C to +13°C. One of the defining characteristics of the Ecatepec de Morelos climate is the significant diurnal temperature variation. This is especially noticeable during the drier months (November to April), when the difference between daytime highs and nighttime lows can be 14–17°C. In the summer months, as the number of rainy days increases (June to September), this gap narrows slightly but remains significant, at around 10–12°C.

Winter in Ecatepec de Morelos, covering December, January, and February, is characterized by mild days and cool nights. During the day, thermometers usually show comfortable values ranging from +20.9°C in December to +23.8°C in February. However, once the sun sets, the temperature drops noticeably, and nights can be quite crisp, with lows ranging from +6.5°C in January to +7.7°C in February. These fluctuations mean that warm clothing is necessary for the evening and early morning hours, even if the day promises to be sunny and warm.

Precipitation in Ecatepec de Morelos is marked by a clear seasonality, yet the total annual amount is extremely low. The year consists of a long dry season and a shorter, relatively wetter period, but even during the "rainiest" months, the intensity of rainfall remains minimal.

The dry season spans from November to May. The months from December to March are particularly arid, with rainfall totals near zero (0 mm) and very few rainy days—ranging from 2 days in February to 4 days in March. In April, May, and November, only 1 mm of precipitation is recorded per month, while the number of rainy days gradually increases toward the end of spring, reaching 9 days in May, and decreasing to 5 days in November.

The wetter season occurs during the summer and early autumn months, from June to October. The peak of precipitation, though still very modest, occurs in July, August, and September, with 5 mm recorded each month. However, these months see the highest frequency of rainy days: up to 25 days in July, 24 days in August, and 21 days in September. This indicates that while the rains are frequent, they are very light or drizzling in nature. June and October see 4 mm and 2 mm of rainfall respectively, with about 16 rainy days each.

In summary, the driest months in Ecatepec de Morelos are December, January, February, and March, when rainfall is virtually non-existent. The highest amount of moisture, albeit in very small volumes, falls from July to September, coinciding with the highest frequency of rainy days.

When planning a trip to Ecatepec de Morelos, it's important to consider the local climate to ensure your stay is as comfortable as possible. Warm weather prevails throughout the year, so the foundation of your wardrobe should be lightweight, breathable clothing made from natural fabrics. Don't forget to pack sunscreen with a high SPF, sunglasses, and a hat to protect yourself from the intense Mexican sun. Comfortable walking shoes are a must, as you'll likely want to explore the surrounding areas.

The key principle when packing for Ecatepec de Morelos is layering. Despite the warm days, evenings and early mornings—especially from November to April—can be quite cool due to significant daily temperature fluctuations. A light jacket, windbreaker, fleece, or sweater will be indispensable. In the winter months (December to February), when nighttime temperatures can drop to +6°C, it is wise to bring warmer layers for evening walks. Long pants or jeans are also appropriate.

While the period from June to September is characterized as wetter due to the increased frequency of rainy days, the total amount of moisture remains very low. This means heavy downpours are unlikely, but frequent, very light drizzling rain is possible. Therefore, instead of a heavy raincoat, it's better to bring a compact umbrella or a light waterproof jacket. Clothing made from quick-drying materials can also be practical during this time. Overall, your luggage should be prepared for sunny days and cooler evenings.
