It may be difficult to believe, seeing as we recently experienced one of the hottest Septembers since records began in 1884, and the second highest October temperature ever recorded, but winter is coming. Or at least slightly cooler weather.
The Hong Kong Observatory is forecasting cooler air from Saturday, when temperatures are set to drop to 19 degrees Celsius, with an average maximum of 25 Celsius, and down to 17 Celsius on Sunday, up to a maximum of 20 Celsius.
The Observatory forecasts the northeast monsoon now affecting the coast of southeastern China will be replaced gradually by an easterly airstream midweek this week and bring a cold front that is expected to hit Hong Kong on Saturday.
Observatory scientific officer Lee Kwok-lun explains, "the contact area of the northern cold airmass and warmer southern air is the cold front. It is expected to invade from the north over the weekend. This cold front is not particular strong, hence we expect the weather to warm up after it passes." However, don't pack away your lighter clothes yet, because it'll warm up again after the weekend.
