If you're planning outdoor activities in Singapore, accept that you'll sweat — the question is how much. I did a 10km run at 7am in March: 27°C, 85% humidity, UV already at 7. Brutal but doable. MacRitchie Reservoir trail is best 6-8am; after that, heat becomes dangerous. The UV index hits 11+ year-round between 11am-3pm — avoid all direct sun. East Coast Park cycling is breezy enough to be pleasant even at noon. Rain comes hard and fast in afternoon thunderstorms, usually gone in 90 minutes. Hydrate aggressively, always.
