Brief By Newsbrief / 7:56 PM on 01 May 2026

The India Meteorological Department (IMD) has projected above-normal rainfall and relatively moderate temperatures across Bihar during May, indicating a shift from typical peak summer conditions. Enhanced pre-monsoon activity is expected to bring frequent thunderstorms, gusty winds, and intermittent showers across most districts.

According to the forecast, maximum daytime temperatures are likely to remain below seasonal averages, generally ranging between 36°C and 38°C, offering relief from extreme heat. However, minimum temperatures may remain slightly elevated, resulting in warmer nights compared to usual patterns.

The IMD also noted that heatwave conditions are expected to be limited this month, with only isolated instances, if any. Changing atmospheric conditions are likely to increase cloud cover and humidity levels, further influencing weather patterns.

Overall, the outlook suggests a comparatively milder May for Bihar, with increased rainfall activity helping ease heat stress and improve environmental conditions across the state.
