Whole world has been battling against the novel Covid19 pandemic that outbroke from Wuhan, China during Dec 2019. Like most other countries, India has also witnessed two Covid-19 waves with second one, during April-May 2021, being more lethal. Important lessons learnt while fighting against Covid pandemic demands never relax attitude until the fight against the pandemic is completely over. To achieve this India launched world’s biggest vaccination program. Continuous concerns are being expressed by different sections of health workers and the government regarding probable, and even more lethal, third wave in near future. Hence this work is undertaken to predict the possibility of third wave. Predictive analysis is based on progression of Covid-19 in the country thus far. Any such prediction shall offer multifaceted benefits in raising timely alarm for country to prepare itself and take measures to tap the onset of probable third wave. ARIMA model was selected for making prediction. Datasets provided by [1],[2] are utilized for the purpose. The model predicted that the latest spurt in Covid19 cases is expected to continue and grow over the remaining part of current year. This spurt can in certain probabilities lead to third Covid-19 wave around the months of Nov-Dec 2021. These predictions are though limited by the recent seroprevalence findings by ICMR and humongous vaccination drive that may retard the onset of third wave. Moreover, confined nature of recent spike (to southern Indian states, mainly Kerala) may mean that the geographical extent of current spurt is comparatively small to become a countywide wave.
