Yes

Go ahead and down vote. It remains a fact that Rajasthan crosses 50 degrees celsius every summer.

The downvotes are likely a result of the single-word reply, with no supporting source for the claim, not for the claim itself.

Technically summer doesn't start until June 21.

Summer solstice? That's midsummer, not the start of summer.

Where? May-early June is peak summer in India. Schools actually start early to mid June.

In dry climates with such hot temperatures, staying hydrated and sweating will keep you cool (or rather, keep you cool enough to not die).

What happens when temperatures like these are reached in high humidity zones where sweat just sticks? Will we simply have entire communities that lack air conditioning dying off?

They will turn into refugees. That's part of why we expect hundreds of millions of climate refugees in the coming decades.

These temperatures in high humidity can be deadly even to healthy and fit humans as our bodies are left without a way to cool down. Currently, they have humidity around 10-20% so it affects the most vulnerable, but global warming may lead to making parts of the world literally deadly to every human being...

https://en.wikipedia.org/wiki/Wet-bulb_temperature

The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed.

Sustained wet-bulb temperature exceeding 35 °C (95 °F) is likely to be fatal even to fit and healthy people, unclothed in the shade next to a fan; at this temperature our bodies switch from shedding heat to the environment, to gaining heat from it.[8] Thus 35 °C (95 °F) is the threshold beyond which the body is no longer able to adequately cool itself. A study by NOAA from 2013 concluded that heat stress will reduce labor capacity considerably under current emissions scenarios.[9]

A 2010 study concluded that under a worst-case scenario for global warming with temperatures 12 °C (22 °F) higher than 2007, the wet-bulb temperature limit for humans could be exceeded around much of the world in future centuries.[10] A 2015 study concluded that parts of the globe could become uninhabitable.[11] An example of the threshold at which the human body is no longer able to cool itself and begins to overheat is a humidity level of 50% and a high heat of 46 °C (115 °F), as this would indicate a wet-bulb temperature of 35 °C (95 °F).

The 2015 Indian heat wave saw wet-bulb temperatures in Andhra Pradesh reach 30 °C (86 °F). A similar wet-bulb temperature was reached during the 1995 Chicago heat wave.

That's the western definition of summer. In some cultures (not sure about India), solstice is the middle of summer.
