Baluahi lies in North-Eastern part of interior India, so its climate is greatly influenced in any season.

"Loo", which are local summer hot winds, blow at a speed of 30–40 km (25 mi).

In a normal year, the monsoon sets in by the third week of June and the rains continue intermittently through September or the early part of October.

In Winters, the temperature may drop to 6°C, creating a thick layer of fog all over the city limiting visibility to 10 to 30 meters.

In the winters of 2009–2010, Baluahi, Bhojpur, and Patna experienced extreme weather with a record decrease in temperature to 4°-5°C.

The higher elevation of Baluahi than the surrounding towns is a concern since more people and the needs for irrigating fields calls for an increased demand on ground water.
