The ideal time to visit the Khartar Vasahi Temple in Palitana is during the cooler months of October to March. During this period, the weather is relatively pleasant with minimal rainfall, allowing for a comfortable pilgrimage and sightseeing experience. Palitana, being in Gujarat, experiences a tropical climate, and hence the summers can be extremely hot, with temperatures soaring up to 42°C (108°F), which can make climbing the stairs to visit the temple quite challenging. Winters are mild and the temperatures range from 10°C to 24°C (50°F to 75°F), making it the perfect weather for tourists to explore the temples at Shatrunjaya hill without the discomfort of scorching heat.
Specially, if you are considering a spiritual visit, the period of Paryushan, the Jain festival usually in August or September, is a significant time where you might want to visit the Khartar Vasahi Temple. Though this is just before the ideal visiting season, it is a vital occasion for Jains, with many festivities and religious activities taking place. Keep in mind this can also mean higher numbers of devotees which may lead to crowded conditions. Additionally, the festival of Diwali is a peak time for the pilgrimage where special prayers and rituals take place. However, if you are looking to avoid the crowd and seek a more tranquil visit, then post-Diwali, from November to March, would be most suitable.
