Haiphong's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Haiphong's climate comes closest to that of Haikou (China) today, though no large city matches it well.
No place on Earth matches it well today either. China: the place on the map

Flood depth is read in a single 1 km cell at the city's centre, in today's climate. Other parts of the city can still flood. The country page names the deepest point near a coastal city in 2080, so its figure can be higher. See how deep a river flood reaches around Haiphong on the live map
