Hong Kong issues first 'very hot weather' warning of 2026

Hong Kong issued its first 'very hot weather' warning of 2026 on Tuesday, as an anticyclone aloft brought fine and extremely hot conditions to the coast of Guangdong. The Hong Kong Observatory issued the alert at 7:45am, the earliest such warning this year. By 10:50am, temperatures in Sheung Shui had already reached 32.3°C, while Ta Kwu Ling hit 31.8°C. The forecaster expects temperatures to hover around 33°C (91.4°F) until Friday, with conditions becoming unsettled toward the end of the week. The nine-day forecast suggests a slight easing over the weekend as the anticyclone weakens.

This heatwave is typical for late May in southern China, but the early timing of the warning underscores the intensity of the current weather pattern. The public is advised to stay hydrated, avoid prolonged outdoor activities during peak hours, and check on vulnerable individuals. The warning system, designed to alert residents to heatstroke risks, will remain active until temperatures drop. The Observatory will continue monitoring conditions as the week progresses.
