The short answer
When to go to Sentosa
February to July is the more comfortable stretch, with February the driest month at about 105 mm of rain, while November to January brings the northeast monsoon and the heaviest rain. Temperatures barely change, staying around 31 to 32 degrees by day, so the main differences are showers and school-holiday crowds. For older travellers, choose a morning start and an indoor afternoon whatever the month, and have a rain plan for December.
