Abstract
High quality instrumental precipitation records are useful in evaluating extreme events suchs as droughts and their recurrence rate at different time scales. The city of Santiago de Chile has a historical rainfall record that started in 1867, making it one of the most complete and extensive in South America. In this work, April through October precipitation have been analyzed over the 1867 - 2015 period in order to evaluate moderate, severe and extreme of droughts occurrence rate based on precipitation reductions. Main results expose an increase of all types of droughts since 1930 and an increase of consecutive drought episodes unprecedented over the instrumental period. In addition, there has been an increase in extreme droughts occurring from May to June since 1950 indicanting very dry winter conditions for the city of Santiago, Chile.
