Hong Kong recorded its highest temperature ever on Monday, reaching 39.3 degrees Celsius, as Tropical Cyclone Dolphin helped intensify an ongoing heatwave, according to thestandard.com.hk.
The reading, reported by the Hong Kong Observatory, surpassed the previous record of 36.9 degrees set in 1884, as noted by AsiaOne. The Guardian also confirmed the day as the hottest in the city’s history, attributing the spike to the typhoon’s outer bands drawing in hot, dry air from the north.
The extreme heat prompted widespread disruption across the city. The South China Morning Post published images of residents wilting under the historic conditions, with many seeking shade or using fans and water sprays to cope. Schools and outdoor workers faced particular strain, though no official emergency measures were reported in the initial coverage.
The record temperature also exposed a gap in Hong Kong’s warning system. The Hong Kong Free Press quoted a former Observatory chief who criticised the city’s heat stress alert as “decorative,” noting that the record-breaking day only triggered the lowest level of warning. The official criticised the system for failing to reflect the true danger posed by such extreme conditions.
The event underscores how tropical cyclones can amplify, rather than relieve, heat in the region. While Dolphin did not make landfall in Hong Kong, its circulation compressed the heatwave into a smaller area, driving temperatures to unprecedented levels.
What to watch next: whether the Observatory revises its heat warning thresholds in response to the criticism, and how the city adapts to more frequent extreme heat events linked to climate change.
