Terms of use

WeatherSG provides general public weather information for convenience. It is not an emergency-warning service and must not be treated as the sole basis for safety-critical, aviation, maritime, medical, or commercial decisions.

Forecasts and observations can be delayed, incomplete, or unavailable. WeatherSG labels source timestamps and warns when data appears stale, but does not guarantee accuracy, availability, or fitness for a particular purpose.

Forecast markers are official area label locations, not geographic forecast boundaries. Rainfall markers are station observations, not radar coverage.

Government data and OneMap remain subject to their respective source terms and attribution requirements.
