Live Singapore (WSSS) runway temperature & next-METAR nowcast

Singapore sits almost on the equator, so its daily high barely moves (σ ≈ 1.4 °C) and forms by mid-afternoon — a tight, low-variance temperature market. polyweather.today tracks minute-by-minute runway temperatures from Singapore Changi Airport (WSSS) (WSSS) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where Singapore's temperature is heading before the next METAR prints.
