Located in the North Indian state of Uttar Pradesh, it faces almost the same weather conditions as Lucknow, Delhi, Chandigarh, Amritsar, and a few other cities located in and around the plains of northern India. If you are planning to be a part of this mass gathering that will be held in the months of January-February and have little knowledge as to with what climate you will be welcomed.
These are the best months to visit Allahabad. The temperature is pleasant throughout the day, and the flow of water in the rivers is steady and calm which is great for boating or taking a dip in the water. You would also see quite a few migratory birds hovering near the Sangam area during these months. The famous guavas of Allahabad are only available during the winter - these are true to the hype and extremely delicious.
The summer months are extremely hot in Allahabad. Temperature goes as high as up to 45 degrees Celcius during the day, and since almost all of the sightseeing in Allahabad is outdoors, this wouldn't be a good time to visit at all.
Allahabad doesn't see a lot of rain, but the temperature is still quite warm and the flow of the rivers becomes fast and unpredictable. There is also some flooding during some years, and you might not be able to visit the Sangam during this time.
