One of the factors influenced Indonesian rainfall is El-Nino Southern Oscillations (ENSO). It also influenced agriculture productions. The study about ENSO and agriculture production is more concerned on food crop than horticultural crops. This paper aimed to study influences of ENSO on horticulture production and alteration of peak season especially on tropical fruits, mangosteen and durian, in Sumatera Island. The time series data from 1990 until 2010 was used to analysis. The analysis revealed that La- Nina caused the decrease in the production of mangosteen and durian roughly 20-70% while El-Nino 2.5-40%. When El-Nino and La-Nina occurred, the peak season of durian and mangosteen changed. The alteration of peak season vary within provinces in Sumatera Island.
