Bihar Weather : Weak Monsoon Brings Scattered Showesr, Humid Heat Continues

Despite the arrival of the southwest monsoon earlier than usual, most parts of Bihar are experiencing a dry spell marked by high humidity and below-average rainfall. The state capital Patna, along with several districts, received only light to moderate rainfall in the last 24 hours, highlighting the inconsistent nature of this year’s monsoon.

Light Rainfall in Patna, Moderate Showers in Kishanganj, Araria, and Bhabhua

According to the latest data from the Patna Meteorological Centre, the monsoon’s grip over Bihar has remained weak. Patna experienced only light showers overnight, contrary to residents’ expectations of heavier rainfall. On the other hand, districts such as Kishanganj, Araria, and Bhabhua recorded 30 to 50 mm of rain — among the highest in the state during the same period.

In contrast, most other districts reported only 10 to 15 mm of rainfall, a clear indication that the monsoon’s strength has yet to be fully realized across Bihar.

South Bihar May Receive Relief Today, IMD Warns of Heavy Rain in Kaimur and Rohtas

The India Meteorological Department (IMD) has issued a heavy rain alert for Kaimur and Rohtas districts today. Winds up to 40–50 km/h are also expected to accompany the downpour, which may offer some temporary relief from the humid conditions gripping the region.

Scattered rainfall is likely in 24 districts, while light rain is forecasted at one or two places in 14 other districts, particularly in South Bihar. Northern districts may only see light drizzles or remain dry.

Monsoon Remains Inconsistent Despite Early Onset

Although the southwest monsoon arrived earlier than expected this year, its overall impact on Patna and surrounding areas has been limited. In fact, according to rainfall records, Patna has received 13 mm less rainfall compared to the same period last year.

Interestingly, other major cities in Bihar — including Gaya, Bhagalpur, Valmikinagar, Dehri, Forbesganj, and Darbhanga — have seen better rainfall this season than last year. For instance, Gaya has recorded 144 mm more rain than the previous year.

Despite these isolated improvements, the broader picture remains concerning. Meteorologists predict below-average rainfall for Bihar in July, raising fears of potential drought-like conditions if the trend continues.

Current Temperature and Air Quality Across Key Cities in Bihar

Here’s a look at the latest temperature and AQI (Air Quality Index) levels across major cities:

(Data from Saturday)

Despite marginally lower temperatures in some areas, the high humidity levels have made the weather feel much more oppressive. The “feels-like” temperature across the state remains high due to excessive moisture in the air.

Humidity Becomes a Major Concern Across the State

With the monsoon stalling, the humidity across Bihar has surged, creating severe discomfort for residents, especially in urban areas. The combination of high temperatures (30–38°C) and moisture-laden winds is increasing the risk of heat-related illnesses like dehydration and heatstroke.

In Patna, locals are dealing with hot, muggy mornings and uncomfortable evenings — a pattern that’s repeated across Muzaffarpur, Purnia, and Bhagalpur. The weather department has warned that this pattern may persist if monsoon activity doesn’t intensify in the coming days.

What to Expect in the Coming Days

Heavy Rain Likely in Southern Bihar

The IMD forecasts moderate to heavy rain for parts of Kaimur, Rohtas, and adjoining districts. These areas may benefit from short-term agricultural relief.

Scattered Drizzles in Northern Bihar

Districts in North Bihar such as Sitamarhi, Motihari, and Madhubani may see only light rain or isolated drizzles, further aggravating rainfall deficits.

Humidity to Continue

Despite sporadic showers, humidity will remain intensely high, especially in regions that miss out on rainfall.

Impact on Agriculture and Rural Livelihoods

The delayed and weak monsoon poses a major challenge for Bihar’s farmers, particularly those dependent on rain-fed agriculture. July is critical for the sowing of paddy, maize, and pulses, but inconsistent rainfall is delaying agricultural activities.

Farmers in regions like Magadh, Mithilanchal, and Seemanchal are especially worried. Local officials may need to prepare contingency plans involving diesel subsidies for irrigation or alternative cropping strategies if rainfall doesn’t pick up soon.

As of now, Bihar’s monsoon performance in 2025 remains below par. While select districts like Gaya and Kishanganj have recorded decent rain, most of the state continues to battle scorching heat and intense humidity. With below-normal rainfall forecast for July, both citizens and authorities must stay alert and prepare for any climatic eventualities.
