Greenness in Ward 27, The Msunduzi
October 2026: about as green as a normal October in Ward 27, The Msunduzi (0.37 on the greenness scale; normal is 0.34). The satellite saw 93% of the area.
The greenness score (NDVI) is how green the land looks from space, from about 0 (bare ground, rock, water) to about 0.9 (dense green growth). It follows rain, season, crops and fire. A month’s figure is the mean over the whole place where the satellite saw the ground (clouds hide some).

Pale bars: seen over less than half the place, so less sure. The second reading is from a coarser European satellite product; it reads a little lower as a rule.

Greenest against normal: 2025 (+0.24). Least green: 2017 (−0.57). Our monthly record starts in January 2017; the normal reaches back to 1984. A year’s figure is the mean of its months seen over half the place.

How we worked this out
Two readings: Digital Earth Africa (Landsat and Sentinel-2, 30 m) and, as a check, Copernicus’s 300 m NDVI. Ward by ward they move together (median correlation 0.98). From 2022 Digital Earth Africa reads about 0.01 NDVI further above CLMS than it did in 2018 to 2021, so part of a recent “above normal” may be the sensors rather than the land; CLMS, read on its own, shows the same greener years (2022, 2025 and 2026).
The normal for each month is Digital Earth Africa’s 1984 to 2020 average from Landsat. Above or below normal is measured in standard deviations of that month over those years: half a standard deviation or more is “above” or “below”, one or more “well above” or “well below”.
What we changed: we averaged Digital Earth Africa’s monthly NDVI over each 2026 ward at 240 m (its own 8 by 8 averages of the 30 m pixels) and wards up to municipalities, districts and provinces by area; CLMS’s three 10-day NDVI images a month averaged the same way.
