Hong Kong's Observatory recorded a peak temperature of 36.9 degrees Celsius on Sunday, breaking the city's temperature record. Typhoon Dolphin delivered the extreme heat by pushing warm air masses across the region, according to the meteorological service.
The previous record stood at 36.6 degrees Celsius, set in July 1967. The new mark reflects how tropical cyclones can dramatically alter local weather patterns by transporting exceptionally warm air from surrounding waters into populated areas. Typhoon Dolphin's circulation created conditions that allowed temperatures to spike above historical norms observed over more than a century of record-keeping.
Hong Kong experiences regular typhoon activity during late summer and early fall. These storms typically bring heavy rainfall and strong winds. However, Dolphin's specific trajectory concentrated warm-air advection over the territory ahead of its full arrival, generating hazardous conditions for residents. The heat spike occurred as the system approached from the southwest.
Climate patterns across East Asia have shifted in recent decades, with warming ocean temperatures extending the warm season and potentially intensifying heat events during typhoon season. Scientists track these temperature records to document long-term warming trends and understand how extreme weather systems interact with changing baseline conditions.
The Observatory continuously monitors conditions across Hong Kong and surrounding areas using automated stations and manual observations. Temperature records from Hong Kong date back to the 1880s, making the dataset one of Asia's longest continuous meteorological records. This historical perspective helps researchers distinguish between routine fluctuations and genuine departures from established climate norms.
Officials issued heat warnings as the record approached, advising residents to limit outdoor activity and remain hydrated. Such advisories prove essential during extreme heat events, particularly in densely populated urban environments where concrete and buildings amplify thermal stress. Typhoon Dolphin subsequently brought typical storm impacts to the region, including rainfall and gusty winds that followed the temperature spike.
