Japan is expected to have a warm climate until the 30th of December, before temperatures drop, paving the way for a cold New Year's Eve. This weather prediction is coming at a time when everyone is preparing to celebrate the end of the year in their unique and fun ways. However, it is advisable to bundle up for those who will be celebrating outdoors due to the anticipated drop in temperature.

Weather updates are important in Japan, with each season bringing unique festivals, activities and traditional practices, especially around New Year's Eve. A colder than usual New Year's Eve could potentially affect outdoor events and celebrations, which is why people maintain a keen interest in temperature forecasts.

Much like in Japan, weather forecasts in the US and EU have a notable influence on holiday festivities and plans, especially outdoor events. However, the nature of those events can be different given the distinct cultural practices in each region.
