Abstract: Among several factors of climate, the El Nino-Southern Oscillation (ENSO) and Sunspot cycles work on inter annual to inter decadal scales and it is believed that while the El Nino-La Nina pressure seesaw of Pacific Ocean affects climate by altering global wind and rainfall patterns, the 11 years periodic variability of sunspot appearance bring changes in insolation and cloud formation. Thus, the role of these two climate forcing seems critical in pushing short term climatic variability’s. This paper attempts to know the impact of these two climatic phenomena on temperature and rainfall patterns at regional scale, and for the purpose the study considers India as the case. Analysis reveals that temperature show a good correlation with sunspot activities, while the effect of ENSO cycle on country`s rainfall is not very clear. However, India`s coastal states record a notable rise in temperatures during El-Nino phase of ENSO phenomenon, and this may be the cause behind fragmented and uneven rainfall over the country during El-Nino years.
