Methodology & sources
Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.
Precipitation — 1991–2020 normals computed from 3 years of daily observations at ST George Muni AP, a weather station, about 1 km from the city centre. The underlying daily records come from NOAA's global station network.
