The climate of Mexico City can generally be described as temperate and pleasant throughout the year, largely due to its high-altitude location. Temperatures here rarely reach extreme values: annual averages fluctuate in a comfortable range from approximately 12.9°C to 18.5°C. During the day, the air usually warms up to 20-26°C, providing warm conditions for walks, while nights, especially in winter months, can be quite cool.

In Mexico City, two main seasons are clearly defined: dry and rainy. The dry season usually lasts from November to April or May. During this period, sunny weather prevails with minimal precipitation, and the months from March to May often turn out to be the warmest of the year. The rainy season begins in June and continues until September-October. This time is characterised by regular rainfall, peaking in July and August when the number of rainy days is at its maximum. Rains usually bring refreshing coolness and contribute to the lush greenery.

This distribution of weather conditions makes Mexico City attractive to visit all year round; however, choosing the best time for a trip depends on your preferences. Dry months are ideal for long excursions and enjoying clear skies, while the rainy season can offer fresher air and lush vegetation, with morning hours often remaining sunny. Consider these features when planning your journey to the capital of Mexico.

The temperature regime in Mexico City is distinguished by moderation throughout the year, yet it has its seasonal features. The average annual temperature ranges from approximately 12.9°C in January to 18.5°C in May. The warmest months are usually April and May, when the average daytime temperature reaches its peak, and maximum values can rise to 25-26°C. During this period, days are predominantly sunny and dry. The coolest months are considered to be December and January, with an average temperature of about 13°C. In these months, nighttime temperatures can drop to 5-6°C, creating a noticeable chill.

Summer months, from June to August, are characterised by warm weather, however, the peak heat has already passed. Average daytime temperatures during this period hold in the range of 21-24°C, and nighttime ones — around 11-12°C. Summer coincides with the rainy season, so frequent afternoon showers bring freshness and somewhat soften the daytime heat. Despite the rains, morning hours are often sunny. Winter in Mexico City (from December to February) offers mild and pleasant days with air temperature often reaching 20-23°C. Nights, however, become significantly colder, and the temperature can drop to 5-7°C.

One of the characteristic features of Mexico City's climate is noticeable diurnal temperature fluctuations. The difference between daytime highs and nighttime lows can be quite substantial, especially in the dry season (from November to May), when it often reaches 14-17°C. This means that even after a very warm day, the evening and night can be quite cool, so it is always worth having a light jacket or sweater with you, especially if you plan walks in the evening or early morning. In the rainy season (summer and early autumn), these fluctuations are somewhat smoothed out but still remain perceptible.

In Mexico City, a pronounced seasonality in the distribution of precipitation is observed throughout the year. The city experiences a distinct dry season, which usually falls on the period from November to April. During these months, the amount of precipitation is minimal. For example, in February and December, an average of 0 mm of precipitation is recorded, making them the driest months of the year, with just 4 rainy days. January, March, and November are also characterised by very low precipitation levels, about 1 mm per month.

The rainy season in Mexico City sets in from May and continues until October, reaching its peak in the summer months. The greatest amount of precipitation falls in July and September, when the average monthly indicator reaches 7 mm. July is also the month with the highest frequency of rains – on average 28 rainy days. In June and August, a significant amount of precipitation (5-6 mm) and a large number of rainy days (17 and 27 respectively) are also observed. Rains during this period are most often intense but can be short-lived, frequently occurring in the afternoon or evening.

Transition months, such as May and October, show a gradual increase or decrease in the amount of precipitation and rainy days. In May, about 2 mm of precipitation falls with 11 rainy days, signalling the approach of the wet season, while in October, the amount of precipitation decreases to 3 mm with 18 rainy days, indicating its conclusion. Snow is not characteristic of Mexico City, so all precipitation falls predominantly in the form of rain.

When planning a trip to Mexico City, it is important to consider its unique climate, characterised by moderate temperatures year-round, but with noticeable daily fluctuations and a clearly defined rainy season. Regardless of the time of year, comfortable walking shoes are your main companion, as exploring this huge city on foot is a pleasure. Always take sunscreen, sunglasses, and a hat with you, as the sun at high altitude can be quite active even on cloudy days. The principle of layering in clothing is the key to comfort in Mexico City. Days can be warm, while evenings and nights, especially from November to May, are cool (minimum temperatures drop to 5-8°C).

In the dry season (from November to April-May), pack light and medium layers of clothing: t-shirts, long-sleeved shirts, a light sweater or fleece jacket, as well as a windbreaker or light jacket. Jeans or comfortable trousers will suit most situations. March, April, and May are the warmest months when the daytime temperature can reach 25-26°C, but evenings still require an additional layer of clothing. In the rainy season (from June to October), especially in the peak months of July and August with a large number of rainy days (up to 28 in July), be sure to take a light waterproof raincoat or jacket and/or a compact umbrella. Rains usually occur in the afternoon, so morning hours are often sunny. Clothing made from quick-drying materials can be useful. Even in the rainy season, do not forget warmer items for the evening, as after the rain, the temperature can drop noticeably.

Besides basic clothing, think about a small backpack for day walks, where you can put a water bottle, an umbrella, an extra layer of clothing, and purchased souvenirs. An adapter for electrical appliances may be needed depending on your country of origin. Although precipitation in the dry season is minimal (0-1 mm from December to April), a light jacket will still come in handy due to temperature changes. In general, preparing for various weather scenarios by choosing versatile and layered clothing will make your stay in Mexico City as comfortable as possible.
