Overview
- The Hong Kong Observatory registered 36.9°C at its Tsim Sha Tsui headquarters on Sunday, and automatic stations reported up to 39.8°C in Sheung Shui, the highest local readings since systematic monitoring began.
- Meteorologists attributed the spike to subsiding sinking air linked to Tropical Cyclone Dolphin that compressed and warmed daytime air over the city.
- The official heat-stress alert remained at the lowest amber level during the peak heat, a gap unions and experts say failed to reflect extreme local conditions on worksites.
- Labour authorities pledged on Monday to review the heat-warning mechanism after unions called for legal recognition of heatstroke as a work-related injury and for more local monitoring.
- Forecasters say hot, humid conditions are likely to continue for several days and the event has renewed calls to update measurement methods and worker protections as regional heat extremes grow more frequent.
