What we changed: we cut ERA5-Land to South Africa, averaged its 9 km grid cells over each ward, municipality, district and province by the area of the place in each cell (MDB boundaries, 2026), took each day’s high and low from 16 of its hourly values, added up days into months, and averaged 1991 to 2020 for the normals.
