The first three days of the new lunar year are expected to be mild, cloudy and warmer than the same time during the last two years, as a relatively humid easterly air stream closes in on the Guangdong coast. Temperatures of around 17 to 23 degrees Celsius are expected during this period. But readings are likely to drop into the mid-teens by Tuesday – the fourth day of the festivities – as a northeast monsoon “surge” returns cooler weather to coastal areas, according to the Observatory. “The first and second days of the new year will be warm in the daytime, but cloud cover is expected to gradually increase,” said Observatory scientific officer Shum Chi-tai. “But people should be aware that by the evening of the third day of the new year [Monday], the weather will turn cooler.” The rest of the week, following the public holidays, is forecast to be mostly fine and sunny. Humidity in the first three days of the new year is forecast to go as high as 95 per cent on Sunday and Monday, while “one or two rain patches” could be expected in the morning and night.
