Australia - weather in April

In Australia, April is the last month of the warm season in the north, as it is a hot, muggy and rainy month in the far north, while it is very hot in the desert and semi-desert areas of the north. Instead, April is the first autumn month in the part of Australia around the Tropic, where it is still hot but much less than in the previous months, and in the southern part, where the climate is gradually cooler and rainier.

In the tropical north, in the Top End of the Northern Territory and in northern Queensland (see Darwin, Cairns), April is the last hot, muggy and rainy month.
On the east coast (see Brisbane, Sydney), it is a fairly warm month, with quite frequent rain, but it is less rainy than in the north, and gradually cooler as you proceed south.
In the Outback, the vast arid or desert inland area (see Alice Springs, Oodnadatta), it is very hot and the sun shines, although every now and then a thunderstorm can break out.
In the south, in the areas where the climate is Mediterranean (see Perth, Adelaide), it is a very mild to quite warm month, with rainfall still quite rare.
In the south-east, in the areas where the climate is oceanic (see Melbourne, Tasmania), the temperature is mild and the weather is variable, sometimes cool and windy, with possible rain, although not very frequent.

As regards to the temperatures, the daily average is still 28/29 °C (82/84 °F) in the Top End of the Northern Territory (see Darwin) and in the desert area north of the tropic, even on the north coast western (see Port Hedland), while it is 22/23 °C (72/73 °F) in the desert areas south of the Tropic (see Oodnadatta, Meekatharra), it is 19/21 °C (66/70 °F) on the east coast (see Brisbane, Sydney) and in Perth , while it drops to 15 °C (59 °F) in Melbourne, in the south-east, and to 13.5 °C (56 °F) in Hobart, Tasmania.
In the desert it can still get very hot in fact the temperature can still reach 40 °C (104 °F), while on the central-southern coasts it can occasionally reach 35 °C (95 °F).
Instead, in the south and in the central-southern inland areas, air masses of Antarctic origin can bring cold at night, with minimum temperatures below 5 °C (41 °F).

As for the rain, as mentioned, April is the last month in which it is abundant in the far north (see Darwin, Cairns), where the climate is tropical with a rainy season. On the east coast (see Brisbane, Sydney), rainfall is moderate, and in certain periods it can be abundant.
In the vast arid areas of the Outback, rain is very rare.
In the south, in the areas where the climate is Mediterranean (see Perth, Adelaide), the rains are still quite rare.
In the south-east, with an oceanic climate (see Melbourne, Tasmania), the rains are quite frequent, and in the western part of Tasmania they are also quite abundant.

In the warm season, central-northern Australia, especially the coasts, can be affected by tropical cyclones. Cyclones mainly affect the northern coasts, although they can sometimes penetrate inland (especially Western Australia), weakening along the way but still bringing heavy rainfall.
Cyclones typically form from mid-November to mid-May, but are more likely from January to mid-April. So we are at the end of the period in which they are most likely.
In the following image, we can see the areas that were affected by cyclones in the period 1950-2005 (the points refer to the eye of the storm, so the affected area is larger).

In April, the sea in Australia is warm enough for swimming in the center-north. In the tropical north it is very warm, on the east coast it is quite warm approximately up to Sydney, on the western coast it is a little cool but basically acceptable in Perth, while in the south, it is cold in Melbourne and very cold in Tasmania.
