Across the 2001-2020 normals, the warmest month in Ranchi is May at 31.7 degrees and the coldest is January at 14.9, a swing of 16.8 degrees over the year. Those are monthly averages for the model cell the city sits in, not readings from a weather station in it.
Rain is heaviest in July, about 349 mm, and lightest in November at roughly 6 mm. Over a full year the cell above Ranchi collects around 1,322 mm.
The months whose average sits between 15 and 24 degrees are February, October, November and December. That band is this page's own definition of mild and is stated so you can disagree with it rather than guess at it.
Humidity peaks in August at 89 percent, and the windiest month is June at 2.7 metres per second. Both are monthly means from the same twenty year series as the temperatures.
Rainfall is not spread evenly: 93 per cent of the year total falls in May, June, July, August, September and October.
3 months average 28 degrees or more: April, May and June.
Every figure here comes from one NASA POWER grid cell, at 23.34, 85.31, covering Ranchi on the 2001-2020 climatology. One cell, one period and one provider for every month, which is what makes the twelve rows comparable with each other.
The source publishes a monthly mean and, separately, the highest and lowest values it recorded in twenty years. Those extremes are not a typical afternoon or a typical night, so nothing here is quoted as one. This page does not say what the daytime high usually is, because this source cannot say it.
Normals are not a forecast. They describe what twenty years averaged to, and any single year can sit well outside them. They also describe a model grid cell of roughly fifty kilometres rather than a weather station, so a coastal city and the sea beside it share one figure.
