Hougang: little of the land is low-lying, so heat comes first: 30 or more days a year at or above 35°C in about 36 years (2062) at today's pace.
At today's pace of emissions. An area-wide estimate for Hougang planning area, not a reading for any one building.

| Heat | Not before 2100 | 206236 years · inside a 99-year lease | 204620 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.
The heat date falls after a 30-year mortgage and inside a 99-year lease.
3 questions to take to a viewing.
Little of the land is low-lying: 2% is below the safety line today and 3% by 2100.
PUB lists 3 flood-prone areas or hotspots in Hougang. 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.
Days at or above 35°C go from 8 to 68 a year by 2100, passing 30 a year by 2062.
| Today | 2050 | 2100 | |
|---|---|---|---|
| Land below the safety line | 2% | 3% | 3% |
| Days at or above 35°C a year | 8 | 20 | 68 |
| 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. Hougang covers 13.9 km² with a median ground height of 11.1 m.
NEA's Kim Chuan Road station recorded 3.1 days a year at or above 35°C in 2014 to 2024 (11 full years). The model gives 4.7 for the same years, as an average over the whole area.

Hotter than most of 55 areas by day; among the 5 hottest at night. Few tall trees to shade streets. 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.
