Private consumption is affected by temporary disturbance factors such as weather conditions, so it is difficult to assess business conditions. In this paper, we propose "Macro Weather Index" as a comprehensive indicator of Japan's weather conditions, and analyze the effect of weather factors on private consumption. We find that a rise in the amount of precipitation depresses consumer spending and a rise in temperature has a positive effect on private consumption in the summer and a negative influence in the winter. We also find that the effects of weather factors on consumption differ by type as well as by item.
