Right (Weather { tempF = 75.0
               , tempC = 24.0
               , humidity = "Humidity: 25%"
               , windCondition = "Wind: S at 16 mph"

               })

Simple case

>>> getWeather' (initApi "en" "utf-8") "moscow"
Right (Weather { tempF = 75.0
               , tempC = 24.0
               , humidity = "Humidity: 25%"
               , windCondition = "Wind: S at 16 mph"
