How to read the map. Each colour is a Köppen-Geiger climate class. The first letter is the major group (A tropical, B arid, C temperate, D cold, E polar); the other letters say how dry it is and how warm or cold. Tap anywhere to see the class under that spot in 1901 to 1930, 1991 to 2020 and, under three emissions scenarios, 2071 to 2099. The codes and names are always given in words, because colour alone is hard to tell apart for some people.

The climate of Haikou

Aw Tropical savannah. Hot all year, with a clear dry season. Warm throughout, with a wet season and a distinct dry season long and dry enough for grassland and scattered trees rather than closed forest.

The 1901 to 1930 map puts Haikou in the same zone, Aw.

The 2071 to 2099 rows are model projections under three emissions scenarios, not forecasts. The 1901 to 1930 row is a reconstruction. All come from Beck et al. (2023).

Under the middle-of-the-road scenario (SSP2-4.5), the model puts Haikou in Am (tropical monsoon) in 2071 to 2099, instead of Aw now. Under the high-emissions scenario (SSP5-8.5) it is Aw (tropical savannah).

Cities with the same climate as Haikou

Other big cities that are Aw (tropical savannah) in 1991 to 2020, at most two per country:

Where Haikou's future climate exists today

In the SSP2-4.5 map for 2071 to 2099, Haikou is Am. These cities are Am in 1991 to 2020, so they give a rough idea of the future climate (the real conditions would differ in many ways).
