Where the figures come from

Cairns's temperatures are measured 27 km from the centre, at Green Island Aws.

Cairns has no rain gauge within 25 km of the centre, so its rainfall comes from a gridded climate dataset read at the city rather than from a gauge further away.

Temperature and rainfall are climate normals, averaged over the years shown. Cairns: 1993-2010 (rainfall 1991-2020) normals, Green Island Aws (27 km from centre). Johannesburg: 2005-2019 (sunshine 1991-2020, rainfall 1991-2020) normals, Johannesburg B / Roosevelt Park (7.3 km from centre).
