October to March is the best time to visit Jaisalmer as the weather during this time is pleasant. Situated in the heart of Thar Desert, the summers are extremely dry and hot and must be avoided. The heat will definitely take a toll on your body, and you will not be able to enjoy your trip to the fullest. During winters, the temperatures fall up to 1 or 2 degree Celsius, especially during the night, so warm clothing is necessary. The monsoon season is also a good time to travel to Jaisalmer. During this time you might get a glimpse of some greenery growing on the arid turf. Jaisalmer is a colourful and vibrant place with an even more beautiful culture that should be a must-visit.
