A partir da aplicação do método de Penman, modificado a evapotranspiração potencial (ETP) diária, foi estimada para quatro estações meteorológicas do Estado do Paraná: Piraquara (Pinhais), Cascavel, Guarapuava e Paranavaí, no período de 1990 a 2000. Essas estações foram adotadas por apresentarem características físicas distintas, como: a altitude, a latitude, a precipitação e a temperatura. Estimou-se a média mensal, o desvio padrão e o coeficiente de variação. Os valores da ETP média anual para Pinhais, Guarapuava, Cascavel e Paranavaí foram de 1137 mm, 1212 mm, 1271 mm e 1580 mm, respectivamente.
