Delhi

October to March is the most comfortable sightseeing window. October and November usually bring warm days and festival activity, while December and January can be cold and foggy in the mornings. Air quality can deteriorate during late autumn and winter, so sensitive travellers should check forecasts. February and March offer pleasant days before the heat intensifies. April to June is extremely hot; outdoor sightseeing belongs in early mornings and evenings. The July-to-September monsoon lowers temperatures but adds humidity, sudden rain and occasional waterlogging.
