I also thought about wet bulb and checked the humidity in Delhi, which seems to be just 7 % or so. According to wet bulb calculators that's still good, like around 23 °C wet bulb.

Interestingly the wet bulb temperature calculators that I tried only work until 50 °C, so that was what I put in.

At 50 °C you need about 35 % humidity to get to 35 °C wet bulb.

Regarding your second point: If I'm not mistaken, the hottest month in the region is around May. The temperature is influenced by monsoons, and although the sun peaks higher in summer, it is generally also more cloudy and rain cools of the surface. That's why usually temperatures peak just before rain season.

It's the core temperature for a medium rare steak.

And ask for climate reforms in the country with the politicians

this is the hard part. you will want to take them and the moneyed interests that back them off the map if you want any meaningful change. they've shown begging wont work.

A faulty sensor...A faulty senso responsibility, amirite?

Adding to that

The India Meteorological Department (IMD) said it was examining the data and sensors at the Mungeshpur station after an unusually large variation in temperatures was recorded at the station compared to others.

So the title seems really misleading. Did The Guardian change it, was it earlier the same as the post title?

127°F to be precise

Construction workers have mostly stopped working between noon and 4pm. “The metal rods I’m working with are too hot to touch. Even if I restart work at 5pm, the rods are burning and the heat from the sparks makes it worse,” said Babu Ram, a welder working on a block of flats in New Friends Colony, south of the city centre.

Is this also a sensor anomoly?

Do you have a link to source of that? I'm pretty sure there are many sensors measuring the temperatures in a city that size.
