The rainfall is the only natural source for the people & animals in the hilly areas and depend on the rainfall for their agricultural purpose and domestic use. Uttarakhnad usually suffers from the heavy rainfall, cloud bust during monsoon. Therefore, we planed a long-term study to analysed the pattern and variability of the rainfall during year 2010 to 2019 over the Uttarakhand, India. For this, We have extract data and analysed daily rainfall dataset from the Tropical Rainfall Measuring Mission (TRMM), and observed that the coefficient of variation for the rainfall is maximum in March and minimum in July which represents that the rainfall is the most variable in March and most stable in July between the year 2010 to 2019 over Uttarakhand. We observed the high rainfall events of Kedarnath during June 2013. Month of July shows a declining trend after 2014 to 2018 as well we also observed a related pattern of rainfall in month of august after eight years.
