The period of consistent heavy rain in the state of Assam during September damaged tea crops badly in Upper Assam where many tea-growing areas are virtually submerged. Upper Assam produces more than 50 percent of the country's total tea output and 70 percent of the total North Indian production. It also accounts for 60 percent of total tea production in the state.
Tea production in North India was first hit by scanty rainfall and now by excessive rain. The weather is playing truant in North India since October last year. The best tea producing months in North India, July to October, have taken a hit and henceforth, the production will gradually taper off with the season coming to a close from January.
