For April, below median rainfall is likely (60pc to 80pc chance) for most of Western Australia, South Australia, western and northern Victoria, western and central New South Wales, and areas near the southern Gulf of Carpentaria coast. Above median rainfall is likely for the northern Cape York Peninsula (60pc to 80pc chance) and some areas of eastern Queensland (60pc to 65pc chance).
For April to June, below median rainfall is likely to very likely (60pc to greater than 80pc chance) for the majority of Australia. Exceptions are for the northern Cape York Peninsula, where above median rainfall is likely, and south-eastern parts of Queensland, coastal New South Wales and southern Tasmania, which have close to equal chances of above or below median rainfall.
Past accuracy of April to June long-range forecasts for chance of above median rainfall has generally been high for most of western, northern, and eastern Australia, with moderate skill for much of southern Australia, extending into parts of the inland north-east of Western Australia and the south and inland west of the Northern Territory.
Warmer than average days for most of Australia during April to June
For April, above median maximum temperatures are likely to very likely (60pc to greater than 80% chance) for much of Australia except for most of Victoria along with southern and eastern New South Wales where maximum temperatures are equally likely to be above or below median.
For April above median minimum temperatures are likely to very likely (60pc to greater than 80pc chance) for most of Western Australia, northern and eastern Queensland, Tasmania, Victoria, southern South Australia, and south-eastern New South Wales.
April to June maximum temperatures are likely to very likely (60pc to greater than 80pc chance) to be above average across much of the country, excluding some areas of northern Queensland, central coastal New South Wales and central to north-eastern Victoria.
April to June minimum temperatures likely to very likely (60pc to greater than 80pc) to be warmer than average most of Western Australia excluding the Kimberley, northern parts of the Northern Territory, northern Cape York Peninsula, the eastern Queensland coast, New South Wales east of the Great Dividing Range, Victoria, Tasmania and the far south-east of South Australia. Below median temperatures are likely (60 to 70pc chance) for areas of central Australia and between the Flinders district in South Australia and western New South Wales.
Past accuracy of the April to June chances of above median maximum temperature long-range forecasts has been moderate to very high across most of Australia. For minimum temperatures, accuracy has been moderate to high for most of Australia, with moderate to low skill for parts of mainland south-east Australia and southern and west coast Western Australia.
