The best time to visit Nawalgarh is during the cooler, drier months, from October to March.
During this period, the weather is pleasantly mild, with daytime temperatures typically ranging from 20°C to 28°C. This makes it ideal for exploring the town's famous havelis and frescoes on foot without the discomfort of extreme heat or humidity. The clear skies are also great for photography.
For travellers interested in local festivals, visiting in February or March might coincide with Holi, the festival of colours, offering a unique cultural experience. However, be aware that accommodation might be more booked up and prices slightly higher during these popular times.
