The Hong Kong Observatory has urged the public, particularly the elderly and chronically ill, to prepare for cooler weather in the next few days.
Its Assistant Director Dr Cheng Cho-ming said local temperatures dropped significantly this morning due to cold air brought by an intense northeast monsoon.
He said the minimum temperature will drop to about 12 degrees Celsius in the urban area tomorrow, and a few degrees lower in the New Territories.
Mornings will remain cool in the next few days.
Dr Cheng reminded the elderly and the chronically ill to take precautions against the cold.
He said the public can use the observatory's mobile app MyObservatory and website to check localised weather conditions and the nine-day forecast.
Senior Citizen Home Safety Association Chief Executive Officer Irene Leung said sharp temperature changes can trigger respiratory diseases or complications with chronic illnesses.
She reminded seniors to beware of the upcoming weather changes and to seek help immediately when feeling unwell. She also called on people to check on elderly relatives who live alone.
The Centre for Health Protection advised the public to avoid alcohol as drinking will chill the body instead of keeping it warm. This is because alcohol dilates blood vessels and accelerates body heat loss.
The centre also reminded parents to keep babies warm, but not overdress them to avoid overheating.
