Jane's Weekly Update: 12th December 2025

We have a brief burst of heat in the southeast, followed by showers and storms to the east of the trough which brings a cool change. This will slowly progress northeastwards across eastern Australia over the weekend.

That means the southeast is at the top of the never ending temperature roller coaster, and about to head to the bottom - before the next jump up in temperature mid next week.

That timing also means that southeast Queensland doesn't see the storms until early next week, while Sydney has them on Friday, and then again later Saturday into early Sunday.

Meanwhile, the heat doesn't abate in the west until later on Monday. That heat will arrive in the southeast mid next week.

BoM and ECMWF guidance are at odds with each other as to which parts of the country are set for rain later next week. Euro likes it to come down through western NSW and VIC (one to watch if you are harvesting), and spread across Queensland.

BoM has a very different picture, keeping the rain confined to the western inland.

For the week of Christmas, Euro has a very tropical pattern, with rain confined to the northern half of the country. BoM is slightly different, pushing it down into the south of WA and SA.
