West Australians are gearing up for a "very unusual" run of hot November weather, with the temperature tipped to reach the high 30s for the next five days. 

New Zealand researchers say changing weather dynamics could be influencing the formation of larger holes in Antarctica's ozone layer, but others debate the new study's findings.

Storms carrying the risk of heavy rain, large hail, and damaging winds are set to hit much of northern and eastern Australia this week while Western Australia bakes under a potential record-breaking November heatwave.

The current El Niño phase of the Pacific Ocean is forecast to peak during the coming months as one of the strongest on record, laying the platform for unprecedented global temperatures through 2024.

Residents across Victoria are on heightened alert for thunderstorm asthma outbreaks this week, but how does stormy weather combine with pollen levels to create such chaos?

Memories of Black Summer remain strong for many in this South East Queensland region, where heavy fuel loads and parched conditions have locals preparing for the worst.

An aurora australis visible to the naked eye has been seen across Western Australia in the brightest display of southern lights in years.

Experts say Victoria's hayfever season could be worse than average, with high-to-extreme grass pollen levels expected from today.

As extreme weather events become more frequent, a new report from the nation's key agency for information and statistics on Australia's health and welfare unpacks the impacts.

El Niño is tipped to bring scorching temperatures to the east, but its impact is less clear in WA. However, there's another climate driver that will bring some serious summer heat.

Firefighters say dry lightning has caused more than a dozen fires across Queensland this week, sparking concerns for authorities battling El Niño conditions. 

The cyclone not only formed outside of the normal cyclone season, it is now the earliest, strongest system ever recorded in the Southern Hemisphere — by a long way. So what allowed it to become so strong so early on?

A perfect storm of conditions sees a unique weather phenomenon form above a Wheatbelt town, lasting for a few fleeting minutes.

While most are mating calls, the wrong noise in the wrong area can also leave a cricket, cicada or other bug in mortal peril.

Temperatures will climb early this week, before widespread rain in NSW helps neutralise fire threats in the state.

Residents of south-east NSW were treated to a surprise mid-spring snowfall on Monday, while in the north searing heat sent temperatures to their highest October levels in more than a decade.

A quick glance at the national forecast this weekend and you could be forgiven for questioning what season we're in. ABC meteorologist Tom Saunders explains what is driving the country's weather disparity.

One of the main drivers behind Australia's year to year rainfall and temperature variability is approaching levels not seen since the summer of 2019.

Climate researchers at the Bureau of Meteorology hope a new system will prevent situations where some agencies are declaring an El Niño event and others aren't.

One wet day does not make a season, and despite this week's soaking across large parts of Victoria and NSW, this spring is still likely to become one of Australia's hottest and driest on record.

New data shows the Earth's average surface air temperature was 0.5C above the previous warmest September on record, in 2020.

The Sunshine state has seen one of its warmest September days on record, with authorities warning the heatwave is only the beginning of what's to come.

Firefighters are eagerly awaiting a cold change as high temperatures and strong winds hit the east coast.

It was Peruvian fishermen, hundreds of years ago, who first noticed and named El Niño. Little did they realise they had named one of the most consequential climate drivers on Earth. This is how it works.
