Kolkata Weather: A Tropical Tapestry

Kolkata, the “City of Joy,” experiences a distinct tropical wet-and-dry climate, characterized by hot, humid summers, a monsoon season, and pleasant winters. Understanding this cycle is key to appreciating and navigating life in this vibrant metropolis.

Summer (March – May): Scorching Heat and Humidity

Summer in Kolkata can be intense. Temperatures frequently soar above 35°C (95°F), often reaching 40°C (104°F) or higher. The high humidity, typically ranging between 70% and 90%, exacerbates the heat, making it feel even more oppressive. This period is marked by long sunny days and relatively infrequent rainfall. Heatwaves are common, necessitating precautions such as staying hydrated, avoiding outdoor activities during peak hours, and wearing light, breathable clothing. Power outages, though less frequent than in the past, can still occur, adding to the discomfort.

Monsoon (June – September): Relief and Disruption

The monsoon season brings much-needed relief from the sweltering heat. The southwest monsoon winds arrive in Kolkata, typically in early June, bringing with them heavy rainfall. While the monsoon lowers the temperature slightly, the humidity remains high. Kolkata receives a significant portion of its annual rainfall during this period. The city often experiences intense downpours, leading to waterlogging in many areas and causing traffic disruptions. However, the lush greenery and the cooler evenings during the monsoon create a unique charm. The occasional break in the rain provides opportunities to enjoy the city’s street food and cultural attractions.

Post-Monsoon (October – November): Transition to Winter

October and November mark a transition period from the monsoon to winter. The rainfall gradually decreases, and the humidity starts to drop. The temperatures become more moderate, making it a pleasant time to visit Kolkata. Days are generally sunny and warm, while evenings and nights are cool and comfortable. This is a popular time for festivals and outdoor activities, as the weather is ideal for exploring the city’s many attractions.

Winter (December – February): Pleasant and Mild

Winter in Kolkata is the most agreeable time of year. Temperatures typically range from 10°C (50°F) to 25°C (77°F). The humidity is low, and the skies are usually clear. Days are sunny and mild, while nights can be quite cool, requiring light woolens. This is the peak tourist season in Kolkata, as the weather is perfect for sightseeing and enjoying the city’s cultural events. The pleasant weather also makes it a great time for outdoor dining and picnics.

Weather Alerts and Considerations

Kolkata is prone to occasional cyclones, particularly during the pre-monsoon and post-monsoon seasons. It’s essential to stay informed about weather forecasts and heed any warnings issued by the meteorological department. Waterlogging during the monsoon can be a significant inconvenience, so it’s advisable to check traffic conditions before traveling. Overall, understanding the weather patterns in Kolkata helps residents and visitors alike to plan their activities and enjoy all that this vibrant city has to offer.
