Weather in Jamshedpur in May

The month to avoid. Of the twelve, May is the one to avoid. Daytime highs average 40.7 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.

May ranks 12 of 12 — near the bottom of Jamshedpur's year. December is the month that works, and the swing between the two is 76 points, which is a different holiday rather than a slightly better one.

Rain on 15 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.

What the averages hide

Averages flatten a month, and this one hides a few things: 30 days of the month clear 35 °C — that is not a heatwave, it is the month. Across the twenty years measured, the hottest May day reached 48 °C and the coldest night fell to 21 °C, and the wettest single day dropped 82 mm — roughly 80% of the month's rain in one day.

May is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest May on record still delivered 177 mm against 40 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 102 mm average is a reasonable planning figure, not a promise.

Wind is light at 7.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 50%.

How May sits in the year

Temperatures hold steady either side: 40.5 °C in April, 40.7 here, 36.2 in June. Nothing about the timing within the month matters much. Rain is the thing that moves: June brings 7 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in May

May is at or near the longest days of Jamshedpur's year: 13.2 hours of daylight, gaining 0.5 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 30.6 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within May itself the daily swing is 14.4 °C, so mornings and afternoons need different clothes.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

May in Jamshedpur versus nearby

If Jamshedpur is one option among several, the nearby comparison is worth making. Ranchi is close enough to be a coin toss — within a degree on temperature, 5 days less rain. Kolkata is close enough to be a coin toss — 3.2 °C cooler, 2 days more rain.

So: May is a compromise. December is 76 points better and is what Jamshedpur is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
