Climate of Sydney

The climate of Sydney, Australia is humid subtropical (Köppen: Cfa), shifting from mild and cool in winter to warm and occasionally hot in the summer, with no extreme seasonal differences since the weather has some maritime influence. Contrasting temperatures are recorded in the western suburbs, as Sydney CBD is more affected by the oceanic climate drivers than the hinterland (due to moderation by the Pacific Ocean).

Despite the fact that there is no distinct dry or wet season, rainfall peaks during summer and autumn months, and is at its lowest just around the middle of the year, though precipitation can be erratic throughout the year. Precipitation varies across the region, with areas adjacent to the coast being the wettest.

In the February 1938 issue of The Home, journalist Basil Burdett wrote, "...Even Melbourne seems like some grey and stately city of Northern Europe compared with Sydney's sub-tropical splendours." In 2023, Sydney was placed at 9th place by Stars Insider for having the best weather in the world.
