Tanglin: what a changing climate means, and when

Tanglin: little of the land is low-lying, so heat comes first: 30 or more days a year at or above 35°C in about 57 years (2083) at today's pace.

At today's pace of emissions. An area-wide estimate for Tanglin planning area, not a reading for any one building.

Coastal	Not before 2150	Not before 2150	Not before 2150
Heat	Not before 2100	208357 years · inside a 99-year lease	205428 years · inside a 30-year mortgage
Flash-flood downpours, island-wide	Not before 2100	209064 years · inside a 99-year lease	205630 years · inside a 30-year mortgage

Coastal: another tenth of the area's land sits below the safety line (3 m above mean sea level plus projected sea-level rise). Heat: 30 or more days a year at or above 35°C. Flash-flood downpours: days with 50 mm or more of rain across Singapore reach 1.5 times their 1995–2014 level; one date for every area, since the rain model can't tell neighbouring areas apart. For local flooding, see PUB's list below. Mortgage and lease are counted from today.

How these are worked out

Ground heat in Tanglin today

Tree cover	54% of land
Ground by day, vs island	−0.7°C 15 of 55, 1 = coolest
Ground at night, vs island	+0.6°C 31 of 55, 1 = coolest

Cooler than most of 55 areas by day; in the middle at night. Satellite readings of the ground surface, not the air: Landsat by day (2016–2025), MODIS at night, ESA WorldCover for trees. They describe today, not a forecast.
