Singapore Singapore Weather in August — Climate Guide
August in Singapore is Moderate
August is Moderate for Singapore.
August is the National Day month. The August 9 National Day Parade — the city's annual celebration of independence from Malaysia (1965) — is the year's most significant civic event. Ticketed grandstand viewing is by lottery to citizens only, but free views from Marina Bay and the Padang are accessible. Fireworks at 8:20 PM are visible from across Marina Bay.
Indonesian forest fires sometimes generate haze in Singapore (the PSI Index reports air quality). August-October is the higher-risk window — check NEA.gov.sg before outdoor activities. Most years are mild; severe haze years (2015, 2019) saw outdoor schools closed.
