Influence of Altitude and Proximity to the Gulf:
Merida’s relatively low altitude and proximity to the Gulf of Mexico play key roles in shaping its temperature profile. The city is situated just 10 meters (33 feet) above sea level, which allows for warmer temperatures to prevail throughout the year. Additionally, the proximity to the Gulf creates a maritime influence, which moderates the temperature fluctuations and provides a refreshing breeze. The combination of these factors results in a more consistent and pleasant climate compared to other cities in Central Mexico.
Clouds in Mérida, Mexico
Mérida, the capital city of the Mexican state of Yucatán, is characterized by its tropical savanna climate, which features distinct wet and dry seasons. During the wet season, from May to October, the skies are often cloudy, as moist air from the Gulf of Mexico moves inland and condenses. These clouds can bring heavy rainfall, thunderstorms, and occasional hurricanes. The cloudy conditions during the wet season can provide welcome relief from the scorching sun and high temperatures that are common in Mérida.
During the dry season, from November to April, the skies in Mérida are typically clearer, with fewer clouds. However, the occasional cold front from the north can bring clouds and rain to the region. These cold fronts can also bring strong winds and a drop in temperatures. The clear skies during the dry season provide ample opportunities for stargazing and enjoying the warm, sunny weather that Mérida is known for.
Historical Precipitation Patterns
Merida, Mexico, lies in the Yucatan Peninsula, a region known for its tropical climate. Historically, the city has experienced significant precipitation, with an average annual rainfall of approximately 1,000 mm (39 inches). The rainy season typically lasts from May to October, bringing heavy downpours that often result in flooding. During these months, Merida receives the majority of its annual precipitation, contributing to its lush vegetation and vibrant ecosystems.
Recent Trends and Climate Change
In recent decades, Merida’s precipitation patterns have shown some changes. While the city still experiences heavy rainfall during the rainy season, the overall annual precipitation has declined slightly. Scientists attribute this to a combination of factors, including climate change and urban development. As global temperatures rise, the atmosphere can hold more moisture, leading to more intense rainfall events but with less frequency. Additionally, urban expansion and deforestation in the surrounding areas have altered local weather patterns, affecting precipitation in Merida. Climate change projections suggest that extreme weather events, including heavy rainfall and droughts, may become more common in the future, posing challenges to water management and infrastructure in the city.
Average Rainfall and Distribution
Mérida, the capital of Yucatán, Mexico, experiences distinct rainfall patterns throughout the year. The city receives an average of 40 inches (1,000 mm) of rainfall annually, with most precipitation occurring during the wet season from May to October. During this period, heavy downpours are common, often accompanied by thunderstorms and occasional flooding. The driest months are January and February, when rainfall typically drops below 1 inch (25 mm).
Seasonal Variations
The onset of the rainy season is influenced by the seasonal movement of the Intertropical Convergence Zone (ITCZ), a low-pressure area that brings moist air from the Atlantic and Gulf of Mexico. As the ITCZ shifts northward during the summer months, it increases precipitation over Mérida. During the dry season, the ITCZ moves southward, resulting in a significant decrease in rainfall. This distinct seasonal variation in precipitation has a notable impact on the city’s vegetation, water resources, and agricultural activities.
Historical Snowfall in Merida
The city of Merida, located in the tropical state of Yucatan, Mexico, is known for its hot and humid climate. However, on December 25, 1997, a rare and unprecedented event occurred – snowfall. This extraordinary weather phenomenon was caused by a combination of factors, including an unusually strong cold front and moisture from the Gulf of Mexico. The snowfall lasted for approximately 30 minutes, covering the ground with a thin layer of white powder. While it quickly melted away, the event left an unforgettable mark on the city’s history.
Impact and Significance
The snowfall in Merida had a profound impact on the community. Many residents had never witnessed snow before, and it brought a sense of wonder and excitement. The event also sparked scientific curiosity and led to studies into the meteorological conditions that made it possible.

It is often referred to as the “White Christmas” or the “Snowfall of the Century” and remains a treasured memory for the people of Merida.
Average Sunshine Hours
Mérida, located in southeastern Mexico, enjoys an abundance of sunshine throughout the year. On average, the city receives approximately 3,000 hours of sunshine annually, with a monthly average ranging from 245 to 270 hours. This remarkable sunshine duration is attributed to the city’s geographic location within the rain-shadow area of the Yucatán Peninsula, which shields it from the prevailing winds and moisture from the Gulf of Mexico. As a result, Mérida experiences a predominantly dry and sunny climate, providing ample opportunities for outdoor activities and recreation.
Seasonal Variations in Sunshine
While Mérida boasts year-round sunshine, the amount of sunshine does vary slightly throughout the year. During the wet season, which typically lasts from June to October, there may be occasional periods of cloudy or rainy weather, reducing the average sunshine hours. However, even during this time, Mérida still receives a significant amount of sunshine, with an average of 5-6 hours per day. In contrast, the dry season, from November to May, brings with it longer days and more consistent sunshine, with an average of 8-10 hours of sunlight per day. During this time, the skies are usually clear, and the weather is warm and pleasant, making it an ideal time to visit and enjoy the outdoor attractions that Mérida has to offer.
Phases and Visibility
The Moon’s appearance in Mérida, Mexico, undergoes the full cycle of phases, ranging from new moon to full moon. The new moon phase marks the moment when the Moon is not visible, as it is aligned with the Sun and its dark side is facing Earth. As the Moon orbits Earth, it gradually becomes visible as a thin crescent. Over the course of a month, the Moon waxes until it reaches the full moon phase, when it is fully illuminated and appears as a bright circle in the night sky. After the full moon, the Moon wanes, gradually decreasing in size and brightness until it disappears again during the new moon phase.
Seasonal Variations
The exact timing of the Moon’s phases in Mérida can vary throughout the year due to the Earth’s tilt on its axis. During the Northern Hemisphere’s summer months (June-September), the Moon is higher in the sky, resulting in brighter and more dramatic moonlit nights. Conversely, during the winter months (December-March), the Moon appears lower in the sky, leading to dimmer and less visible phases. Additionally, the position of the Moon relative to the horizon can affect its perceived size and brightness. When the Moon is near the horizon, it can appear larger and more orange due to atmospheric scattering.
Seasonal Humidity Patterns
Merida, the capital city of the Mexican state of Yucatan, experiences a tropical climate characterized by high humidity throughout the year.
