The relationship between the Himalayan snow cover extent and the onset of summer monsoon over Kerala, India, has been examined for the period 1971-81. The snow cover extent over the Himalayas has been derived from satellite images and Northern Hemisphere snow cover charts. India Meteorological Department (IMD) provides the onset dates of summer monsoon over Kerala. This preliminary study indicated that mean monthly snow cover area over the Himalayas for the months February through April had positive correlation (correlation coefficient 0.62) with the onset dates of summer monsoon over Kerala. This implies that large snow cover over the Himalayas for the months February through April was likely to be followed by an late onset of summer monsoon over Kerala and vice versa.
