If you live in or plan to visit Bihar, knowing the weather ahead can save you a lot of hassle. Below you’ll find the latest forecast, a quick rundown of seasonal trends, and simple tips to stay comfortable no matter what the sky throws at you.
Right now, most parts of Bihar are seeing temperatures between 28°C and 35°C during the day, with evenings cooling down to 22°C‑24°C. The monsoon season is in full swing, so expect scattered showers in Patna, Gaya, and Muzaffarpur. The India Meteorological Department (IMD) predicts a 60%‑70% chance of rain over the next 24 hours, especially in the northern districts.
If you’re heading out, carry a light rain jacket or an umbrella. The showers are usually brief, but heavy bursts can cause local flooding, especially near the Ganges and Kosi riverbanks. Keep an eye on water‑level alerts if you’re traveling near those areas.
**Summer (April‑June):** Temperatures often climb above 38°C. Heatwaves are common, so stay hydrated and avoid midday outdoor work.
**Monsoon (July‑September):** This is the rainiest period. Average rainfall is around 100 cm, with July and August being the wettest months. Flooding can happen, so follow local news for any evacuation notices.
**Winter (December‑February):** Days are pleasant at 20°C‑25°C, but nights can drop to 8°C‑10°C in the northern plains. Light woolens are enough.
Understanding these patterns helps you pack the right clothes and plan activities ahead of time.
For real‑time updates, check the IMD website or a trusted weather app. Most services offer hourly rain predictions, which are useful if you have a train or flight to catch. Setting a simple “Bihar weather” alert on your phone can keep you in the loop without extra effort.
