COVID-19 causes various kinds of life problems, including the occurrence of a global health crisis, social, psychological problems, and a prolonged economic crisis. Climate-related dynamics have an impact on patterns of human health and disease. This study aimed to investigate the effect of climate on the outbreak of COVID-19. This study used a literature review approach on research on climate and Covid-19, using the Google Scholar, Scienceirect. The article taken was original research in the recent year. It was found that the effect of climate change had a significant relation to the increase in Covid-19 cases. Therefore, it can be concluded that climate is a risk factor for increasing the outbreak of the Covid-19 Virus. However, one previous study predicted that with a mathematical model that included human demographic conditions and mobility, it was concluded that a tropical climate could help inhibit the oubreak of the virus because tropical climatic condition could make the virus more volatile.
