There have been six consecutive hot nights since Saturday, tying the record for the longest continuous period of hot nights in May since records began at the observatory.
“Actually, looking back at May in previous years, we usually start to see some hotter weather,” acting assistant director of the observatory Choy Chun-wing told an RTHK programme.
“If we look back around April and May, there have been some very hot days, so, it’s not particularly early this year for the heat to begin.”
Choy said the heat is expected to continue on Friday, with maximum temperatures of around 35 degrees in urban areas and one to two degrees higher in the New Territories.
The observatory predicts that Friday’s maximum UV index will be approximately 11, indicating an extremely high level of intensity.
