Sydney records hottest June since 1859 with mean temperature of 16.1°C

Sydney recorded its hottest June on record, with the Bureau of Meteorology reporting a mean temperature of 16.1 °C at Observatory Hill. The figure eclipses the previous benchmark of 15.7 °C set in 1991, confirming that the winter month has surpassed all earlier records since meteorological observations began in 1859.

The temperature rise was noted early in the month, when preliminary data indicated a warmer-than‑usual June. However, the final confirmation came on Friday, when the Bureau released the official statistics. The 16.1 °C mean reflects a sustained period of spring‑like warmth across the city, a pattern that has drawn attention from climatologists and the public alike.

This record‑breaking June underscores a broader trend of rising temperatures in Sydney’s winter months. While the Bureau has not issued a formal warning, the data provide a clear benchmark for future climate monitoring and underscore the importance of continued observation of the city’s long‑term weather patterns.
