Bhisho has cooled about 5.2°F between 1971 and 2024.
About 1.0°F per decade, measured from Bhisho's official daily weather records, 1971–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Bhisho's climate has warmed more slowly than most other cities in South Africa.
What has actually changed
Each card compares the 1970s (the first ten years of the

Wetter on average
Bhisho's temperature, year by year
Average temperature for each year from 1971 to 2024.
a warmer-than-average year a cooler-than-average year
Each bar is one year. Most recent years sit above the older ones.
Some recent years still came in cool — warming is a slope,
not a straight climb.
In day-to-day terms, that long-term shift shows up as about 4 fewer days above 90°F compared with the 1970s.
When in the year the change shows up
How much warmer each month is now than in the 1970s.
Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
September has cooled the most — about 7.9°F. The warming runs across the whole year, not just one season.
Methodology & sources
Temperature — 1991–2020 normals computed from 29 years of daily observations at East London, a weather station, about 42 km from the city centre. The underlying daily records come from NOAA's global station network.
