Cirrus clouds, thin and high-altitude, are often seen on clear days and indicate stable atmospheric conditions. Stratocumulus clouds, which form as a blanket of low-lying clouds, frequently appear during the transition between the monsoon and dry seasons.

Annual Precipitation Patterns

Mumbai experiences a tropical monsoon climate, characterized by distinct wet and dry seasons. The monsoon season, which lasts from June to September, accounts for the majority of the city’s annual precipitation. During this period, Mumbai receives heavy rainfall brought by the moisture-laden winds blowing from the Arabian Sea. On average, Mumbai receives over 2,000 mm of rain annually, making it one of the wettest cities in India.

Seasonal Variations

The onset of the monsoon typically occurs in early June, bringing a sudden and intense burst of rainfall. The heaviest rainfall is usually observed in July and August, with average monthly precipitation exceeding 600 mm. As the monsoon winds weaken in September and October, the intensity of rainfall gradually decreases. The dry season extends from November to May, during which time Mumbai receives very little precipitation. However, occasional showers may occur during the winter months, particularly in December and January, providing some respite from the dry conditions.

Rainfall Patterns:

Mumbai experiences a tropical monsoon climate, characterized by heavy rainfall during the southwest monsoon season (June to September). The city receives an average of 2,200 mm of rainfall annually, with nearly 80% of it concentrated during these monsoon months. The Western Ghats mountain range, along the city’s eastern flank, acts as a barrier, forcing the moisture-laden clouds to condense and release copious amounts of rainfall over Mumbai. The city’s proximity to the Arabian Sea also contributes to its high rainfall, as warm, moisture-rich air from the sea rises and cools, leading to cloud formation and precipitation.

Variability and Extremes:

Rainfall in Mumbai exhibits significant variability, both annually and seasonally. While the city generally receives ample precipitation during the monsoon season, its intensity and timing can fluctuate considerably. Monsoon rains can be particularly heavy in July and August, causing flooding and landslides in low-lying areas. In contrast, there can be significant dry spells or delayed monsoons, leading to water shortages and droughts. Climate change is further intensifying these variations, with extreme rainfall events becoming more common. The city has experienced severe flooding in recent years, highlighting the need for effective drainage and flood management infrastructure.

Unprecedented Snowfall in Mumbai

Mumbai, India, experienced an unprecedented snowfall on January 10th, 2023, marking a historic event for the coastal metropolis. The city, known for its warm, humid climate, was transformed into a winter wonderland as heavy snow blanketed the streets, rooftops, and trees. This extraordinary phenomenon was a sight to behold, drawing crowds of people eager to witness the rare spectacle.

The cause of the snowfall was a combination of several factors. A strong cold front from the north brought icy temperatures to Mumbai, creating the ideal conditions for precipitation. Additionally, an upper-level disturbance trapped cold air over the city, leading to the formation of snow clouds. These clouds released their icy payload, blanketing the city in a thick layer of snow. The snowfall lasted for several hours, causing disruption to daily life and transportation. However, the sheer beauty of the snow-covered city made up for any inconvenience, creating memories that will last a lifetime.

Moon’s Visibility in Mumbai, India

Mumbai, India’s bustling metropolis, experiences the moon’s phases like any other location. The moon’s phases are influenced by its orbit around the Earth, and its visibility in Mumbai varies depending on these phases. During the new moon phase, the moon is positioned between the Earth and the sun, making it invisible. As the moon orbits around the Earth, it gradually becomes visible as a crescent shape. The first quarter moon occurs when the moon has completed one-quarter of its orbit, becoming half-illuminated.

As the moon continues its journey, it becomes a waxing gibbous moon, appearing three-quarters illuminated. The full moon phase occurs when the moon is opposite the sun, resulting in a fully illuminated disk. This sequence repeats as the moon enters the waning phases, gradually diminishing in visibility until it becomes a new moon again. The duration of each phase is approximately 7 days, completing the full cycle in about 29.5 days.

Summer Humidity in Mumbai

During the summer months (March to May), Mumbai experiences high humidity levels due to the warm and moist air masses that originate from the Arabian Sea. The average relative humidity during this period ranges between 70% and 85%. The high humidity creates a sultry and oppressive atmosphere, making it uncomfortable for outdoor activities. The combination of heat and humidity can also lead to heat-related illnesses such as heat exhaustion and heat stroke, especially for the elderly and those with health conditions.

Monsoon Humidity in Mumbai
