Sea level rise in Ho Chi Minh City: how high will the water get?
Under intermediate emissions, sea level at Ho Chi Minh City is projected to rise about 19 cm by 2050 and 55 cm by 2100 compared with 1995–2014 — or 76 cm if emissions stay very high. That is close to the global average rise of 56 cm. There is no tide gauge close to Ho Chi Minh City in the IPCC dataset, so this uses the nearest regional grid point, which does not capture local land subsidence; where the ground is sinking fast, the real rise will be higher.
Projected sea level rise at Ho Chi Minh City, 2020–2150 (cm vs 1995–2014)
| Year | Low | Intermediate | Very high |
|---|---|---|---|
| 2030 | +8 cm (0–17) | +8 cm (1–17) | +9 cm (1–17) |
| 2050 | +18 cm (4–32) | +19 cm (5–34) | +22 cm (8–37) |
| 2070 | +28 cm (7–50) | +32 cm (11–55) | +38 cm (17–62) |
| 2100 | +42 cm (10–78) | +55 cm (22–92) | +76 cm (42–116) |
| 2150 | +68 cm (14–127) | +92 cm (36–156) | +132 cm (69–210) |
What it means for Ho Chi Minh City
The average rise is only part of the story. What people notice first is flooding: higher seas let ordinary high tides and storm surges reach further inland. The IPCC projects that extreme sea levels which used to occur once a century will happen at least once a year at more than half of the world's tide gauge locations by 2100.
Sea level will keep rising for centuries even after emissions stop, because the deep ocean keeps warming and ice sheets keep melting. Under very high emissions, rises well beyond these ranges cannot be ruled out if parts of the Antarctic ice sheet become unstable — see tipping points.
To see which streets are at risk, use a local flood map: the projections here can be explored station by station in the NASA Sea Level Projection Tool.

Frequently asked questions
Will Ho Chi Minh City be underwater?
Not in the sense of the whole city disappearing this century, but the sea at Ho Chi Minh City is projected to rise about 55 cm by 2100 under intermediate emissions (likely range 22–92 cm), and about 76 cm under very high emissions. Low-lying districts face more frequent flooding from high tides and storm surges well before then; whether a specific street floods depends on local elevation and flood defences.
How much will sea level rise in Ho Chi Minh City by 2050?
About 19 cm (7 inches) compared with 1995–2014 under an intermediate scenario, with a likely range of 5–34 cm. Up to 2050 the emissions scenarios give similar results, because much of this rise is already locked in.
Why is sea level rise in Ho Chi Minh City different from the global average?
Projections at a single coast include vertical land motion (sinking or rising land), changes in ocean currents and the gravitational effects of melting ice sheets. That is close to the global average rise of 56 cm.
