The climate in Sitamarhi is a humid subtropical monsoon climate, with pronounced seasonal variations in both temperature and rainfall. The year can be clearly divided into three main periods: a hot and mostly dry summer, a humid and rainy monsoon season, and a mild and comfortable winter. Travelers should be prepared for significant weather changes depending on the month of their visit.

The winter period, spanning from December to February, is considered the most favorable time for a visit. During this time, the weather is dry and sunny, with pleasant daytime temperatures and cool nights. The pre-monsoon season begins in March, as temperatures rise rapidly, peaking in April and May, which makes these months very hot. A true shift in the weather occurs with the arrival of the monsoon season, which lasts from June to September. This period is characterized by high humidity and frequent rain, especially in July and August, when it can rain almost daily. From October, the monsoon recedes, and the weather becomes dry and comfortable once again.

The climate in Sitamarhi is characterized by distinct seasons with significant temperature fluctuations throughout the year. The coldest month is January, when the average temperature is about 16.1°C, and nightly lows drop to an average of 10.3°C. The peak of the heat occurs from April to June. April is the sweltering month, with average maximum temperatures reaching 36.4°C. June is the hottest month by average daily temperature (30.8°C), due to very warm nights.

The summer period in Sitamarhi is hot and humid, especially with the onset of the monsoons. From May to September, daytime temperatures consistently stay above 32°C, and nights remain very warm, with averages around 25-26°C. High humidity accompanying the monsoon rains (20-28 rainy days per month) makes the heat feel particularly intense and muggy. During this time, daily temperature fluctuations are minimal.

Winter, by contrast, offers mild and comfortable weather. From December to February, daytime temperatures are pleasant, ranging from 21°C to 25°C, creating ideal conditions for travel. Nights during this period become cool, especially in December and January, when the thermometer drops to 10-12°C. In dry months, such as November or April, the difference between day and night temperatures is quite significant and can exceed 12-13°C, so it is worth bringing warm clothes for evening walks.

The city of Sitamarhi experiences pronounced seasonal rainfall, typical of a monsoon climate. The year is clearly divided into a long dry period and a wet rainy season, which falls during the summer and early autumn months. In winter and spring, rain is very rare, creating comfortable conditions for sightseeing.

The rainy season, or monsoon, usually begins in May, gains strength in June, and reaches its peak in July and August. These two months see the maximum number of rainy days—about 28 each—meaning that precipitation occurs almost daily. July is the wettest month of the year by rainfall volume. September also remains very rainy, concluding the main monsoon period.

The dry season covers the period from late autumn to mid-spring. November is the driest month, when, according to statistics, there are no rainy days at all. From December to April, precipitation is also minimal, although rare and brief showers may occur. During this time, the weather is mostly clear and dry.

When planning a trip to Sitamarhi, it's important to choose the right wardrobe to stay comfortable in any weather. The climate is predominantly hot, so your luggage should mainly consist of light and breathable clothing made from natural fabrics like cotton or linen. During the hot season, which lasts from March to October, loose T-shirts, shorts, skirts, and dresses are essential. Be sure to pack reliable sun protection: sunscreen with a high SPF, sunglasses, and a wide-brimmed hat or cap.

From June to September, Sitamarhi enters the monsoon season, characterized by high humidity and frequent heavy rains. During this period, you will need a sturdy umbrella or a lightweight waterproof jacket. Clothes should be both light and quick-drying. Opt for footwear that can handle getting wet—water-resistant sandals or rubber flip-flops are ideal. Despite the rain, temperatures remain high, so you won't need warm clothing.

From November to February, a cooler and drier season arrives. Days remain warm and pleasant, but evenings and nights can be quite chilly, with temperatures dropping to 10–13°C. Layering is the best approach during this time. You'll be comfortable in a T-shirt during the day, but for the evening, it's worth having a light jacket, sweater, or fleece. Regardless of the season, comfortable walking shoes, such as sneakers or loafers, will be your best companion for exploring the city and its surroundings.
