The climate in Mexicali, located in Mexico, is characterized as desert and arid. This means the city experiences very high temperatures in summer and mild winters, with minimal rainfall throughout the year. Visitors should be prepared for dry air and intense sunlight for most of the year, making sun protection and staying hydrated particularly important.

There are two distinct main seasons in Mexicali. Summer, covering the months from June to September, is extremely hot and dry. Average maximum temperatures during this period regularly rise above 40°C, and in July and August, they can reach 44°C. Nights bring some relief but remain warm. Winter, from December to February, offers much milder weather with average temperatures around 15-16°C and pleasant daily highs in the region of 21-23°C. Spring and autumn are short transitional periods with gradually increasing or decreasing heat.

The most notable feature of the weather in Mexicali is the almost total absence of precipitation. According to the data provided, rainfall amounts to 0 mm every month, and the number of so-called "wet days" is minimal (from 0 to 3 per month), which likely indicates days with increased cloudiness rather than any significant rain. This exceptional dryness defines the character of the local landscape and daily life.

The climate in Mexicali is characterized by significant temperature fluctuations throughout the year. The hottest months are July and August, when the average temperature rises above 35°C, and daily highs regularly exceed 40°C, sometimes reaching 44°C in July. The coolest months are considered to be December and January, with an average temperature of around 15°C. During these months, night-time temperatures can drop to 8-9°C, while during the day the air warms up to a comfortable 21-22°C.

The summer period in Mexicali, spanning from June to September, is distinguished by extreme heat. Average daily temperatures in June are already around 32.4°C, peaking at 36.3°C in July. The daytime heat can be exhausting, with maximums often exceeding 40-43°C. Nights bring some relief but remain warm, with minimum temperatures in the range of 23-28°C. It is important to note that summer in Mexicali is very dry, with zero rainfall, which intensifies the sensation of heat. Daily temperature fluctuations in summer are significant, with the difference between the daily high and nightly low potentially reaching 15-18°C.

Winter in Mexicali, from December to February, is quite mild and pleasant. Average temperatures hover around 15-16°C. During the day, the thermometer usually rises to 21-23°C, creating comfortable conditions for walking. Nights can be cool, with minimum temperatures around 8-9°C, so a light jacket or sweater would not go amiss. As in summer, noticeable daily temperature variations are observed in winter, although they are less pronounced than in the hot season. Precipitation in the winter months is also minimal.

The city of Mexicali in Mexico is characterized by an extremely arid climate throughout the year. According to the provided monthly average data, rainfall amounts to 0 mm in all months. This indicates that any significant rain here is a great rarity, and the region experiences a constant moisture deficit.

Despite zero figures for rainfall amounts, statistics record so-called "wet days". Most likely, these are days with extremely insignificant precipitation not measurable in millimeters (for example, very fine drizzle), or days with high humidity, fog, or heavy dew. The highest number of such "wet days" occurs in August – an average of 3 days. An average of 2 "wet days" is observed in January, February, July, September, and December. In March, April, October, and November, one such day is recorded.

The driest months, even based on the "wet days" criterion, are May and June, when such days are completely absent. Thus, there is no clearly defined rainy season in Mexicali in the traditional sense of the term. Travelers should expect predominantly dry and sunny weather year-round. Given the high temperatures even in the winter months, snowfall in Mexicali is impossible.

When planning a trip to Mexicali, it is important to consider its desert climate, characterized by very hot summers and mild winters, as well as minimal rainfall throughout the year. Regardless of the season, be sure to bring high SPF sunscreen, sunglasses, and a hat to protect against the intense sun. Comfortable walking shoes are also essential, as you will likely be moving around a lot while exploring the city.

In the summer months, especially from May to September, when temperatures can rise above 40°C, preference should be given to light, loose clothing made from natural breathable fabrics such as cotton or linen. Light colours will help reflect the sun's rays. Do not forget to drink plenty of water to avoid dehydration. In the winter months, from November to March, days are usually warm (around 21-26°C), but evenings and nights can be cool (around 8-12°C). Therefore, it is recommended to use the layering principle: t-shirts or light shirts for the day and a sweater, fleece, or light jacket for the evening. In transitional seasons, such as April and October, the weather is also warm, and layering will be your best friend.

Given that the data shows extremely low rainfall levels (0 mm in most months) and very few rainy days, the need for an umbrella or serious rain gear is unlikely. If you are travelling during months when 2-3 "wet days" are indicated, these will likely be very insignificant precipitation, and a light, compact water-repellent windbreaker will be more than sufficient if you want to be prepared for anything. The main focus in your wardrobe should be on sun protection and adapting to temperature fluctuations between day and evening, especially in the non-summer months.
