Patna: The Southwest Monsoon is likely to reach Bihar around June 15, offering relief from the ongoing heatwave conditions across several parts of the state. However, meteorologists have cautioned that the monsoon season could be affected by El Niño, potentially resulting in below-normal rainfall later in the year.
According to the Meteorological Department, the monsoon is expected to make landfall on the Kerala coast around June 4, approximately four days later than its normal onset date. After advancing through southern India and the Bay of Bengal region, weather officials will issue a more detailed forecast for Bihar after June 8.
Monsoon Expected by Mid-June
Weather experts said the monsoon’s arrival in Bihar is expected to remain close to its usual schedule. If prevailing atmospheric conditions remain favourable, rainfall activity could begin in several districts by the end of the second week of June.
The expected arrival of the monsoon is likely to provide relief to residents facing intense heat across large parts of the state.
Heatwave Conditions Continue
Several districts in South and West Bihar are currently experiencing severe heatwave conditions. The Meteorological Department has indicated that heatwave conditions may persist until June 10.
Rohtas district recently recorded a maximum temperature of 45.1 degrees Celsius, which officials believe is the highest temperature recorded there in nearly 14 years. Temperatures have also crossed the 40-degree Celsius mark in more than 13 districts across Bihar.
In contrast, districts in the Seemanchal region have witnessed comparatively pleasant weather. Areas including Katihar, Kishanganj, Purnia and Araria have received intermittent rainfall and thunderstorms over the past month, keeping temperatures close to 30 degrees Celsius.
Concerns Over El Niño Impact
Meteorologists have expressed concern over the possible strengthening of El Niño conditions in the coming months. Some weather assessments have indicated the possibility of a stronger El Niño phase developing during the monsoon season.
Experts said rainfall patterns may remain relatively normal during June and July, but there is a risk of reduced precipitation during August and September. Such a scenario could increase the likelihood of drought-like conditions in parts of Bihar.
A prolonged rainfall deficit could affect major crops including paddy, maize, pulses and oilseeds, potentially impacting agricultural output during the kharif season.
Farmers Asked to Prepare
Agricultural experts have advised farmers to take precautionary measures ahead of the monsoon season. They have recommended strengthening irrigation infrastructure, ensuring tube-wells and bore-wells remain operational, and adopting water conservation practices.
Officials said preparedness measures could help minimise crop losses if rainfall remains below normal during the latter part of the monsoon season.
The Meteorological Department has also indicated that rainfall distribution this year may differ from previous years, with northeastern states expected to receive comparatively higher rainfall than Bihar.
