The climate in Siliguri, located in India, can be characterized as subtropical monsoon. There are clearly defined seasons with noticeable fluctuations in temperature and, crucially, rainfall throughout the year. Overall, the weather is warm but includes periods of significant humidity.

The year in Siliguri is divided into three main seasons. Winter, from December to February, is relatively cool and dry, with average temperatures ranging from 15°C to 17°C and minimal rainfall. This is followed by a hot and increasingly humid period from March to May, when temperatures gradually rise, peaking before the onset of the monsoon. The most notable weather phenomenon is the rainy season, lasting from June to September. These months experience the highest temperatures (averaging 26-27°C), heavy rainfall, and the maximum number of rainy days, especially in July and August.

After the monsoon ends, in October and November, the weather becomes drier and more comfortable, with temperatures gradually decreasing. November and December are the driest months of the year. Therefore, when planning a trip to Siliguri, it is important to consider these seasonal changes, especially the pronounced monsoon period.

Siliguri experiences a distinct annual temperature progression, characteristic of a subtropical monsoon climate. The hottest month is usually August, when the average temperature reaches 26.9°C, and daily highs can rise to 29.4°C. July and June are also very warm, with average temperatures of 26.7°C and 26.5°C respectively. The coolest month is January, with an average temperature of 15.1°C, while nighttime lows can drop to 9.3°C.

The summer period in Siliguri, which lasts roughly from May to September, is characterized by hot and humid weather. Average daytime temperatures during these months remain steadily in the 29-30°C range, and nighttime temperatures rarely fall below 21-24°C. High humidity, especially during the peak of the monsoon season (June-August), intensifies the sensation of heat. Transitional months, such as April and October, are also warm, with average temperatures of 24.3°C and 23.9°C respectively, but with less rainfall compared to the peak monsoon.

Winter in Siliguri, covering December, January, and February, is distinguished by mild and comfortable coolness. Average temperatures during this period fluctuate between 15°C and 17°C. During the day, the thermometer usually rises to 20-23°C, while at night it can drop to 9-12°C. Daily temperature fluctuations are most noticeable during the dry winter months (for example, in January the difference between the maximum and minimum temperature is about 11.5°C), whereas in the humid summer months (for example, in July) this difference is significantly smaller, around 4.6°C, due to high cloud cover and humidity.

In Siliguri, there is a pronounced seasonality in precipitation, typical of a monsoon climate. The year is clearly divided into dry and wet periods. The dry season usually lasts from November to February. During these months, rainfall is minimal: November and December are the driest, with practically no rain (0 mm of precipitation and only about 2 rainy days). January and February also remain very dry, with minimal rainfall (1 mm) and a small number of rainy days (4-6 days).

The rainy season, or monsoon, begins gradually from March-April, when the amount of precipitation and the number of rainy days start to increase. The peak of the monsoon occurs during the summer months. July is the wettest month with an average rainfall of 27 mm and practically daily rains (30 rainy days). June (20 mm of precipitation, 29 rainy days) and August (18 mm, 30 rainy days) are also characterized by abundant and frequent rainfall. In September, the intensity of the rains begins to subside (14 mm, 27 rainy days), and October serves as a transition month to the dry season (5 mm of precipitation, 16 rainy days).

Thus, if you are planning a trip to Siliguri and want to avoid the rain, the best time to visit is from November to February. Conversely, from June to September, one should expect frequent, and sometimes heavy, rains typical of the monsoon period in India. Snow is not characteristic of Siliguri, given the average monthly temperatures.

When planning a trip to Siliguri, it is important to consider the local climate to pack your suitcase correctly. In general, comfortable walking shoes will be your indispensable companion, as the city and its surroundings offer many interesting places to explore. From November to February, the weather here is most comfortable: days are warm, with temperatures around 20-26°C, while evenings and nights are quite cool, around 9-14°C. For this period, light jackets or sweaters, long-sleeved t-shirts, and trousers are ideal. Precipitation is minimal at this time, making walks particularly pleasant. In transitional months, such as March, April, and October, daytime temperatures gradually rise, but evenings may remain fresh, so the principle of layering your clothes will be very useful. Do not forget sunscreen and a hat, especially on clear days.

The period from May to September in Siliguri is the monsoon season. It is characterized by high humidity, consistently warm temperatures (averaging 25-27°C, with highs around 29-30°C), and significant rainfall. Particularly intense rains fall from June to August, when precipitation can be practically daily. At this time, a waterproof jacket or a quality raincoat, as well as a sturdy umbrella, become absolutely necessary. It is recommended to prefer light, breathable, and quick-drying clothing, preferably made from natural fabrics. Sandals or other footwear that is water-resistant and dries quickly may also come in handy. Due to the increased humidity and heat during this period, insects are active, so do not forget to bring insect repellent for protection against mosquitoes.
