Drought in Ward 1, Thembelihle
October 2026: no drought in Ward 1, Thembelihle. The last three months had 192% of the usual rain, and the land is much greener than usual.
A drought score for each month from rain, evaporation and how green the land is: 0 is normal, and below −1 is drought. Our estimate from a weather model and from space, not an official drought declaration.

Scores are in steps from normal (the 1991 to 2020 usual for the time of year): 0 is normal, −1 is dry (drier than about five years in six), −2 is very dry (drier than about 49 years in 50). What the scores mean.

Rain and evaporation are modelled estimates from a weather reanalysis, averaged over the whole place, not station readings; greenness is measured from space. This is not an official drought declaration: those come from the National Disaster Management Centre.
How we worked this out
The drought index puts four measures on one scale, each in standard deviations from its 1991 to 2020 normal for the time of year (minus is drier): rain over the last 3 months and the last 12 (from ERA5-Land), rain less evaporation over 12 months (ERA5-Drought’s SPEI, so a hot, dry year counts for more), and how green the land is (from space, since 2017). The index is their mean.
What we changed: we summed ERA5-Land’s monthly rain over 3 and 12 months for each place and fitted it to a gamma distribution per calendar month (1991 to 2020) to get the SPI; averaged ERA5-Drought’s 0.25 degree SPEI and SPI over each place by its area in each cell; and took the mean of the parts.
