About the hko Search Trend

HKO refers to the Hong Kong Observatory, the government meteorological agency responsible for weather forecasting, warnings and climate monitoring across Hong Kong. Established in the late 19th century, the Observatory maintains long-term climate records, operates weather stations and radars, and conducts seismological and geophysical monitoring in addition to routine forecasts. It is best known to the public for issuing Tropical Cyclone Warning Signals (including the significant Signal No. 8 and above) and the Amber/Red/Black Rainstorm Warnings that trigger school and transport responses, and it publishes real-time radar, satellite imagery and observations. In recent years HKO has modernized its public services — expanding digital forecasts, mobile apps and social-media alerts — while deepening climate and urban-weather research (for example on heat stress and sea-level rise). People searching for “hko” or “Hong Kong weather” will typically be looking for current forecasts, typhoon and rainstorm warnings, live radar/satellite displays and guidance on what each warning signal means.
