Weather in Ranchi in October
India · 20-year averages, October
Prime time. If you get to pick your dates, October is the one. Highs average 26.6 °C, lows 18.1 °C, and rain falls on 9 days — nothing in the month is working against you.
October ranks 5 of 12 in Ranchi: past the worst of the year but short of November, which is the month to book if the dates are open.
Rain on 9 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average October reaches 30 °C. Across the twenty years measured, the hottest October day reached 29.9 °C and the coldest night fell to 9.5 °C, and the wettest single day dropped 96 mm — roughly 117% of the month's rain in one day.
This is the volatile part. October rainfall has ranged from 15 mm to 314 mm across the twenty years measured — a 299 mm spread around an average of 82 mm. The average is real but almost no individual October looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.
How October sits in the year
Temperatures hold steady either side: 27.9 °C in September, 26.6 here, 24.4 in November. Nothing about the timing within the month matters much. Rain is the thing that moves: November brings 8 days less of it, so pushing the dates later buys drier weather.
Daylight in October
11.6 hours of daylight, losing 0.6 hours across the month. That is between Ranchi's extremes of 13.6 and 10.7 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 30.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
October in Ranchi versus nearby
If Ranchi is one option among several, the nearby comparison is worth making. Jamshedpur is the weaker option in October — 2.7 °C warmer, 2 days more rain. Patna is the weaker option in October — 4.3 °C warmer, 3 days less rain.
So: October works, with November the better month by 15 points if the dates can move. If they cannot, nothing here should stop you booking.
