Abstract: Due to its production and harvesting system, tea (Camellia sinensis L. ) is unlike any other usual crop. It's a sort of crop that can grow in a variety of temperatures and soils all over the world. Sylhet accounts for 94 percent of total annual production (63 percent in the Moulvibazar area), with the remainder coming from other regions of the country. While Bangladesh is grappling with how to deal with rising domestic tea demand and a global competitive market, climate change poses a threat to tea production. Tea is affected both directly and indirectly by climate change. In general, rising temperatures will have two effects: direct effects on tea growth and scarcity of water for irrigation. As a result, both the direct effect of climate on agricultural productivity and the effective water supply and availability of water for irrigation must be considered. The scope of this research includes a review of several meteorological variables such as rainfall, temperature, solar radiation, wind speed, and relative humidity, as well as their combined impact on crop water needs. The northern and eastern zones of Bangladesh are considered for a thorough analysis. Individual characteristics are examined and compared in order to create a link between climatic influence and irrigational water demand.
