Singapore Grand Prix weather guide
Prepare for equatorial heat, high humidity and October thunderstorms without treating climate normals as a forecast.
Hot and humid is the baseline
Meteorological Service Singapore describes a tropical climate with high temperatures, abundant rain and high humidity throughout the year. October is within an inter-monsoon period.
Thunderstorms can develop quickly
Official climate guidance says October and November can bring severe afternoon and early-evening thunderstorms. This affects entry, walking, entertainment and track operations.
Replace climate with a live forecast
Check official observations and warnings through race week, then again before leaving the hotel. Use sun protection, hydration and a compact rain layer that complies with entry rules.
