Taiwan had a hot and sunny day on Wednesday, a day that was supposed to represent the arrival of winter.

Wednesday marked “Li Dong,” the first day of winter according to the lunar calendar. But the weather was anything but wintry across most of Taiwan. The temperature even got up to 30 degrees Celsius in Taipei, making it shorts and T-shirt weather for visitors to the Chiang Kai-Shek Memorial Hall.

The Central Weather Bureau says such weather has not been unusual for this time of year over the past few years. One meteorologist said temperatures on Li Dong for 2013 and 2014 were around 24/25 degrees Celsius. But since 2015, it has not been unusual for the mercury to reach 30 degrees Celsius and beyond on the so-called first day of winter.
