Woodlands: what a changing climate means, and when

Woodlands: little of the land is low-lying, so heat comes first: 30 or more days a year at or above 35°C in about 5 years (2031) at today's pace.

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

The three dates for Woodlands

	Best case	At today's pace	Worst case
Coastal	Not before 2150	Not before 2150	Not before 2150
Heat	20326 years · inside a 30-year mortgage	20315 years · inside a 30-year mortgage	20315 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.

Has our street or carpark ponded in heavy rain, and what was done about it?
Has the basement carpark taken in water in heavy rain?
What shade or cooling work is planned for the estate?

If you are buying in Woodlands

4 questions to take to a viewing.

Sea level: not before 2150

Little of the land is low-lying: 2% is below the safety line today and 3% by 2100.

Flash floods: inside a 99-year lease

PUB lists no flood-prone area or hotspot in Woodlands. Island-wide, days with 50 mm or more of rain go from 6.6 to 8.7 a year by 2100, reaching 1.5 times their 1995–2014 level by 2090.

Has this street flooded in heavy rain before?
Has the carpark or ground floor ponded in heavy rain before?

Heat: inside a 30-year mortgage

Days at or above 35°C go from 23 to 120 a year by 2100, passing 30 a year by 2031.

Which way does the unit face, and how much afternoon sun does it take?
How much shade and greenery is there around the block?

The numbers

	Today	2050	2100
Land below the safety line	2%	2%	3%
Days at or above 35°C a year	23	49	120
Days with 50 mm or more of rain a year, island-wide	6.6	7.6	8.7

At today's pace of emissions (SSP2-4.5). "Today" is modelled, not measured. Woodlands covers 13.6 km² with a median ground height of 18.1 m.

NEA's Woodlands Avenue 9 station recorded 9.4 days a year at or above 35°C in 2014 to 2024 (9 full years). The model gives 15.6 for the same years, as an average over the whole area.

How these are worked out

Ground heat in Woodlands today

Tree cover	24% of land
Ground by day, vs island	+1.1°C 32 of 55, 1 = coolest
Ground at night, vs island	+0.1°C 12 of 55, 1 = coolest

In the middle of 55 areas by day; cooler than most 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.
