Live Hong Kong temperature & daily-high tracking

Hong Kong's temperature market settles on the Hong Kong Observatory headquarters' Absolute Daily Max to 0.1 °C — not the airport. This page tracks the HKO HQ temperature live — the exact settlement station and precision — cross-checked daily against HKO's official bulletin. polyweather.today tracks minute-by-minute runway temperatures from Hong Kong Observatory HQ (VHKO) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where Hong Kong's temperature is heading before the next METAR prints.

What this page shows

Runway-minute temperatures — per-runway-end readings updated every minute.

Next-METAR nowcast — a backtested estimate of the next METAR's rounded temperature (Pro).

Decision light — a live read on whether the signal is reliable (Pro).

Today's high — the running daily-high METAR reading, with its peak timestamp.

Beijing is free to view without an account; Hong Kong and the other cities need a free login for live data, with real-time decision signals on Pro — see Free vs Pro →
