The Earth's pulse reads the whole world, not this city, so it is the same on every city's page.
Earth's pulse, from 0 to 100. It rises with the number of people in the path of disasters now under way; 90 matches the 2004 tsunami.

2041-2060 compared with 1991-2020, if emissions level off [4] [5]
By the 2050s, Kumasi's climate comes closest to that of Lomé (Togo) today, though no large city matches it well.

If emissions keep rising, no large city has such a climate today; the nearest is Lomé (Togo).

Climates are compared on seasonal temperature and rainfall alone, each difference weighed against the city's usual swings from year to year (the method of Mahony et al. 2017); heat waves, the heat of city streets and the rising sea are left out. All 3 estimates from the climate models, the middle one and the two ends of their range, point to Lomé. [6]
Everything else measured
From the highest among the world's 626 large cities to the lowest.
| Reading | Kumasi | Among 626 large cities |
|---|---|---|
| Tropical nights in 2025, over 20 °C [1] | every night of the year | higher than 93% of large cities |
| Hottest day of 2025 [1] | 38 °C | higher than 64% of large cities |
| Earthquake shaking on firm ground, 10% chance in 50 years [7] | moderate shaking, 0.08 g | higher than 57% of large cities |
| Warming by 2050, if emissions level off [5] | +1.7 °C | higher than 30% of large cities |
| Days with 20 mm of rain or more in 2025 [1] | 3 days | higher than 24% of large cities |
| Drought risk [8] | Medium-High | the same grade as 38% of large cities; higher than 12%, lower than 50% |
| Water stress [8] | Low: under 10% of the available water drawn | lowest grade, like 30% of large cities |
| River flood depth, 100-year event [9] | Dry at the centre; other districts can flood | like 85% of large cities |
| Share of land sinking over 1 cm a year, within 15 km [10] | 0% | like 80% of large cities |
| Land burned in an average year [11] | 0% | like 84% of large cities |
| Tropical cyclone wind, once in 100 years [12] | No hurricane or typhoon reaches here | |
| Share of the land around the centre (a 10 km square) that a 100-year flood from the sea puts under 0.5 m of water or more [9] | Far from the sea: no coastal flooding |
- Flood depth is given for one 1 km square at the city centre, in today's climate.
- Earthquake shaking is given for firm ground in g, the acceleration of gravity: around 0.1 g shaking is strong and can cause light damage, on the US Geological Survey's scale. The figure is the typical value over all the land within 15 km of the centre, not that of one point. Soft ground, such as an old lake bed or river silt, shakes harder.
- Land subsidence comes from a model of satellite radar measurements from 2013 to 2019 in 2 km squares, read over all the land within 15 km of the centre rather than at one point.
- Water stress is the share of the available water drawn every year. Drought risk is how often droughts come, against the area's own usual rain, and how many people and how much farmland they would reach. Both are graded on WRI's own scale.
- If emissions level off: the IPCC's SSP2-4.5 scenario.
- Water stress and drought risk have no rank in the country: they are steps of a scale, and many cities share one.
- Tsunamis and landslides are not rated for a single city here.
