On 30 and 31 October 1964 during the passage of thundersqualls over Colaba, Bombay relative humidity recorded pronounced dip of 29 and 17 per cent respectively. This led to an examination path the wind speed humidity changes associated with passage of squalls during the last 3 years 1962-1964. Frequency distribution of these change in relation to rain show that humidity dip is associated with squal1s occurring before rain while a rise in humidity during squall occurred either during ram or just following the rain. A plausible explanation for the change in the humidity during the passage of the downdraft from the cumulonimbus cell is given.
