Having lived all my life in tropical cities, the first thing that strikes about Jaipur is the weather. Jaipur experiences harsh extremes of climate due to its proximity to the Thar desert. I noticed that most housewives' lives actually revolved around these changing weather conditions with each extreme weather bringing with them their customary tasks and mundane chores.
The summers are very very hot and dry. When I was there the temperatures revolved around 45 C. But since there is no humidity (or very less of it) you won't sweat much as in a tropical place. But the downside is that you will simply need to drink lots and lots of water - about 10 times as much as you would normally. I had to quench my thirst with 2 glasses of water or juice - anything within handreach - after approximately every 20 minutes.
The winters are equally harsh with extremities reaching near freezing temperatures. Most houses or almost all don't have heaters and so even while indoors, people have to rely on several layers of winter clothing to keep warm in the day and sleep under stone-heavy blankets at night.
