The best time to visit the Shri Ram Mandir in Haridwar, Uttarakhand, is during the cooler months of October to April. During this period, the weather is pleasant with the temperature ranging from 10°C to 30°C, which is ideal for sightseeing and participating in religious activities. Haridwar experiences a subtropical climate and the summers (May to June) can be exceptionally hot with temperatures soaring up to 40°C, which might not be comfortable for many visitors. Monsoon season starts in late June and continues until September, and while the rain-washed grandeur of the town has its own charm, heavy rains can disrupt travel plans and temple visit schedules.
Apart from the climate, if you are interested in experiencing the spiritual and cultural vibrancy of Haridwar, consider planning your visit around the major Hindu religious festivals such as Kumbh Mela, Ardh Kumbh, and Kanwar Mela. Kumbh Mela is a massive pilgrimage that gathers millions of devotees, occurring once every twelve years in Haridwar. Ardh Kumbh takes place every six years while Kanwar Mela is an annual event with a significant increase of visitors during the month of Shravan (July-August). Note that during these events, the town becomes extremely crowded, and accommodations must be booked well in advance. For a more peaceful experience, visiting during non-festival times is recommended.
