Do you feel like you need a second shower immediately after walking to the MRT? You aren’t imagining things. As we head into the final stretch of April 2026, Singapore is experiencing extreme weather and it’s projected to last right through to April 30. Over the next few days, you’ll feel as if the sky can’t decide between roasting you alive or washing you away as it soaks your shoes and makes your hair frizzy. Plus, there will be a potential of flash floods due to sudden torrential downpours. Here’s what we know about the April 2026 weather in Singapore.
Will the extreme heat & sudden rain continue into May?
For the period from April 22 to April 30, the forecast brings high temperatures of 34°C and lows of 26°C with scattered thunderstorms, persistent humidity peaking at 79%, UV indexes reaching 9, and winds including 5 mph from the northeast.
This means you shouldn’t let the glorious morning sunshine fool you. In fact, that intense daytime heating is the exact fuel needed to trigger heavy thundery showers in parts of the city-state by the mid to late afternoon.
With conditions flipping from intense sun to sudden rain, preparation is key for your commute across the city-state. Be sure to ditch the heavy fabrics for breathable, moisture-wicking layers that can handle the extreme mugginess, swap your favourite shoes for waterproof footwear, and never leave home without a sturdy umbrella and sunscreen to navigate the sticky, stormy transition to sunshine.
