Average minimum temperatures in all seasons are highest in northern Australia and near the coastal areas, and are lowest in the elevated areas of the south-east. The highest average January minimum temperatures (near 27 °C) are found near the north-west coast, while in winter they exceed 20 °C at some coastal locations in northern Australia and on the Torres Strait and Tiwi Islands. In the mountains of New South Wales, it is not unusual to have average low minimum temperatures dipping below 5 °C in January and −5 °C in July. Comparatively, most inland (non-mountainous) areas south of the tropics have average July minimum between 0 and 6 °C.
