Uttar Pradesh in April

October through March is your sweet spot. Temperatures hover between 15-25°C, perfect for exploring without melting. December and January can get surprisingly chilly in the mornings — pack a light jacket. Diwali in October or November transforms the entire state. Every temple, ghat, and monument lights up. But book accommodations months ahead and expect higher prices. Holi in March brings color chaos, especially in Mathura and Vrindavan. It's magical but messy — wear clothes you don't mind ruining. Avoid April through September unless you enjoy feeling like you're inside an oven. Summer temperatures hit 45°C, and monsoons from July to September flood streets and delay trains. The only exception: if you're here for Kumbh Mela, which happens regardless of season every 12 years in Prayagraj.
