Manali is great place to visit, both in January and March. In January, you can witness the snowfall in Manali and this allows you to enjoy a lot of wintersports as well. Visiting Manali in March allows you to experience the colours of Spring and have a great time enjoying photography and a few trekking adventures.
Hi Sainath, I have narrowed it done by different season that Manali experiences in a year. You can decide if the weather works for you. Manali is a beautiful destination that offers different charms in all seasons. Summers witness Manali turning into an escape from the blistering heat of the plains, while winters dress the town in a graceful garb of white snow. Here's a monthly breakup of Manali's climatic conditions so that you can plan accordingly: September to February: The monsoons draw to an end in September and winter starts setting in from October. The temperature in winter months can go down to -1 °C, so make sure you carry enough woolens to keep yourself warm, especially for the chilly nights.
December end to January is the time when you can enjoy snowfall and the spectacular scenic white views of the surrounding mountains, making it a favourite with the honeymooners. This is the ideal time for adventure enthusiasts who want to go skiing. March to June: Summer steps in from March but the weather is still pleasant. The temperatures during these summer months usually vary between 10°C to 25°C, so you might still need light woolens during the night. This is the perfect time to indulge in outdoor activities such as paragliding, rafting, trekking and mountain adventures in the Solang Valley. This is also the time when the region’s flora is in full bloom lending it the most pristine natural beauty. July-August: Monsoons in Manali can be tricky as the region experiences heavy rainfall, which can also sometimes lead to landslides. But considering a lot of tourists don’t prefer to travel during this time, the prices of hotels tend to drop. Hope this helps!
