Siliguri’s November Weather: Rising Temperatures and Urban growth shaping North Bengal’s Climate

Siliguri, nestled in North Bengal’s foothills, is known for its moderate climate and scenic beauty. However, November 2024 has brought subtle but notable changes to its typical weather patterns, particularly when compared to November 2023. This month’s temperatures are slightly higher than last year, a shift that illustrates not only the effects of global climate change but also the growing impact of local urbanization. Let’s delve into the specifics of these shifts and the ongoing transformations in Siliguri that may be influencing them.

Temperature Changes: November 2023 vs. November 2024

In November 2023, Siliguri’s temperatures were mild, with average highs around 27-28°C and lows close to 15°C. This year, however, the city is seeing highs reaching around 29°C, with nighttime temperatures hovering around 16-17°C. Though this increase may seem minor, it’s part of a broader warming trend seen not only in North Bengal but worldwide. Siliguri’s historical data shows that November is typically cool and comfortable, with about 11 mm of rain and ample sunshine. However, this recent increase reflects a subtle shift towards warmer Novembers that could gradually redefine the city’s climate expectations.

The Impact of Rapid Urbanisation

One of the driving forces behind Siliguri’s warming trend is its rapid urban expansion. In recent years, the city has emerged as a major transport and trade hub in the region, aided by the completion of significant infrastructure projects. The Asian Highway, connecting Siliguri to neighboring countries and states, has boosted local economy and accessibility. Alongside this, multi-story residential complexes and commercial centers have proliferated, especially near key transport nodes like Bagdogra Airport and the city’s main highways.

This development has introduced more paved surfaces and reduced green cover, intensifying the “urban heat island” effect. This phenomenon causes urban areas to retain more heat than their rural counterparts, pushing up temperatures, especially at night. While this urban transformation supports Siliguri’s growth, it also means that residents and visitors may experience slightly warmer days and nights, especially in areas close to major developments.

The Himalayas, just north of Siliguri, are highly sensitive to climate change, which impacts both regional weather patterns and ecosystems. As global warming progresses, cities like Siliguri, with unique geographic positioning near mountain ranges and river plains, may see greater fluctuations in temperature and precipitation patterns.

What’s Next for Siliguri?

As Siliguri continues to grow, urban planners face the challenge of balancing development with environmental sustainability. Green spaces, water bodies, and climate-sensitive infrastructure can help mitigate the warming effects of urbanization. Efforts to promote energy-efficient buildings, sustainable transportation, and urban greenery could play a role in ensuring that Siliguri’s climate remains as comfortable as possible amid ongoing changes.

In conclusion, while Siliguri’s November temperatures in 2024 are only slightly warmer than in 2023, these changes hint at the larger impacts of climate change and urbanization on North Bengal’s weather. With mindful development and sustainable practices, Siliguri has the opportunity to grow while preserving the temperate charm that has long been a hallmark of this gateway to the Himalayas.
