Weekly weather forecast: Singapore's mixed week turns wetter late

Central's week: dry spells between rain chances

From Saturday 17 October through Friday the 23rd, Central alternates between brief rain and drier spells before rain turns widespread late on. A low-pressure system nearby lifts Saturday's rain chance to 50%, before high pressure brings a mostly sunny Sunday at 10%. A low-pressure system nearby again on Monday the 19th still leaves Central mostly sunny with occasional clouds at 20%. High pressure then clears the region: Tuesday keeps a 50% rain chance, while Wednesday turns mostly sunny at 10%. Rain rises from Thursday at 70%, continuing Friday at 60%.

Five locations diverge: Woodlands wetter, Changi drier

Rain chances vary more by location than by day from Saturday 17 October through Wednesday the 21st. Woodlands sees a rain-linked forecast on nearly every day in that stretch, except Sunday the 18th, which turns mostly sunny with occasional clouds. Changi and Jurong West stay comparatively drier, with rain chances mostly at or below 20% across the same days. Sengkang follows that drier pattern on Saturday and Sunday but rises to 50% on Monday and Wednesday, closer to Woodlands than Changi.

Rain turns widespread by Thursday and Friday

After a changeable week with scattered rain chances across the five tracked locations, Thursday the 22nd and Friday the 23rd bring the most widespread rain of the outlook. On Thursday, all five locations reach a 70% chance of rain with occasional sunny spells, the highest of the week. Friday brings a sunny-then-rain pattern everywhere, with Changi, Jurong West, and Sengkang at 50%, and Central and Woodlands at 60%, keeping unsettled conditions through the end of the outlook.
