December weather forecast
Australia

December in Australia signifies the robust arrival of summer, bringing with it a medley of weather conditions that reflect the continent's diverse landscapes and climates.

The central regions of Australia face the unyielding heat that defines the heart of Australian summers. Daylight dominates the vast desert expanses, with the sun casting intense rays upon the arid plains. The nights, in stark contrast to the scorching days, retain a semblance of coolness, providing a much-needed respite.

In the Northern Territory, the wet season is in full swing. Heavy rainfall, thunderstorms, and increased humidity become common features, especially in the tropical northeast. The lushness of the rainforests is accentuated by consistent showers, creating a haven for diverse flora and fauna.

Queensland, with its extensive coastline, witnesses the peak of humidity. The tropics face regular rain, which, while keeping temperatures in check, amplifies the mugginess. The western parts of the state, being more interior, see less rainfall but are not spared from the rising mercury levels.

Western Australia, especially its interior, fully embraces the dry and hot conditions of summer. Rain is a rare occurrence, and clear skies become the norm. Coastal areas, although still humid, experience lesser rainfall than their eastern counterparts.

New South Wales exhibits a dynamic weather pattern in December. While coastal areas gravitate towards beach activities due to the enticing sea temperatures, the inland regions, especially the eastern highlands, undergo a noticeable surge in temperatures. However, the occasional cloud cover or brief shower does provide short-lived relief.

South Australia's vast interiors continue their arid trend, with very minimal rainfall. Meanwhile, the southern coastlines, influenced by the Mediterranean climate, might witness occasional rain showers. Daytime temperatures are consistently high, urging people to seek shade and hydration.

Tasmania, always a tad cooler than the mainland, welcomes summer with milder temperatures. The island's temperate disposition ensures that even in December, the heat remains relatively moderate, making outdoor activities a pleasure.

Victoria witnesses a stark contrast in its weather. The northern regions face higher temperatures, synonymous with an Australian summer. Meanwhile, the coastal regions, including the Victorian Alps, exhibit milder conditions interspersed with occasional rainfall.
