Australian Weather

The school holidays start at the end of the week for Victoria and Queensland, but people heading to the mountains will find almost no snow in what is already one of the worst starts to the Australian snow season on record. The official snow depth at Spencers Creek – the highest of three New South Wales sites where Snowy Hydro regularly measures snow throughout the cooler months – is currently zero.

Only once previously, in data going back to 1954, has Spencers Creek registered a snowless reading in July. But that’s the scenario facing Australia’s snowfields with just a few days left in June 2026, with no fresh snowfalls expected before the end of the month. The 2026 season so far: too wet, too warm for natural snow June 2026 has not been a good month for Australian snow enthusiasts. A minor snowfall just before the traditional King’s Birthday long weekend early in the month brought a reading of 14.4 centimetres at Spencers Creek on June 10. But that snow has since melted or been washed away by rain in unseasonably warm temperatures. Across southeastern Australia and the Australian Alps this June, both maximum and minimum temperatures have averaged around 2-3°C above the long-term June average. For example, the average daily maximum at Victoria’s highest ski resort Mt Hotham has been 3.5°C to date in June 2026. That might sound chilly, but the long-term June average is 1.5°C. Too warm even for snowmaking Compounding the frustration for our ski resorts and their visitors is that nights have generally been too warm for snowmaking. Even this week, with the mercury falling below zero for at least four consecutive nights at alpine resorts like Perisher (NSW) and Falls Creek (Vic), the atmosphere has been a little too humid to fire up the snow guns with effect. As we explained recently in our story on how snowmaking works, cold nights aren’t the only part of the snowmaking equation. When humidity is high and the air is saturated, the tiny droplets of water sprayed out by snow guns won’t freeze even if the temperature is slightly below zero. READ MORE: Snowmaking begins in Australia: but how does it work? Quite simply, there have been too few influxes of cool air from the Southern Ocean to produce snowfalls or even suitable conditions for snowmaking across Australia’s alpine region during June. This has been due largely to blocking high pressure systems forcing the band of westerlies and their snow-producing cold fronts further south than usual – a typical set-up when we are in a positive phase of the Southern Annular Mode (SAM).

There’s a ski lift or two open on the beginner runs at Thredbo (NSW), Perisher (NSW) and Mt Buller (Vic) but that’s about it. Mt Buller and Thredbo have both benefited from a new type of snowmaking infrastructure generally called "ice factory" snowmaking or "all-weather" snowmaking. Instead of spraying out a mixture of compressed air and water into the freezing night air, you make crushed ice inside a giant refrigerated unit that looks like a shipping container, then spread it out onto the slopes through a hose. Technically it’s ice, not snow, but its texture is almost indistinguishable from natural or snowmaking snow once numerous skis or snowboards have slid across it. When is a significant snowfall likely to arrive? The good news is that models are starting to align towards the probability of a snowy system arriving a few days into July.

As the image above shows, temperatures will at last be below average across southeastern Australia by about July 4, after weeks when that part of the country was consistently red (warmer than usual) most days and nights. That’s a pointer to the coming snowy system, although how much moisture is associated with the potential cold outbreak remains to be seen. But for the next week or so, the picture remains bleak, and indeed yet more rain will be a feature of the weather in the alpine area in coming days. If you’re heading to the “snow”, pack the hiking boots and a raincoat too. Please check the Weatherzone snow page for the latest forecasts, live snow cams and more.

Earth’s global average sea surface temperature has reached record-breaking high levels over the past week as El Niño gains strength in the tropical Pacific Ocean. According to the ECMWF’s ERA5 dataset, Earth’s global average sea surface temperature reached 20.86°C on Sunday, June 21. This was the highest value on record for this time of year, beating the 20.83°C from the same date in 2023 and 2024, which were the two warmest years on record for global ocean temperatures. Another highly-regarded dataset from NOAA – the OISST V2.1 – registered a global daily sea surface temperature of 20.97°C on June 21. This also beat that dataset’s previous record of 20.92°C from the same date in 2024. It’s important to note that these near-real-time ocean temperature values are preliminary estimates and may be revised as the data is quality-controlled. Why are the oceans so warm? Two of the main drivers behind this month’s record-breaking ocean warmth are El Niño and climate change. El Niño is associated with a large tongue of abnormally warm water in the central and eastern tropical Pacific Ocean. This year’s El Niño was declared earlier this month by NOAA and the BoM and sea surface temperatures in the central Pacific are currently about 1.7°C above the 1991-2020 average. This exceptionally warm water is helping push the global average ocean temperature to record high levels.

The polar regions shaded in black are excluded when calculating the global average ocean temperature, primarily to exclude areas covered by sea ice. In addition to the influence of El Niño, most ocean basins across the globe have been getting warmer in recent decades in response to climate change. According to NOAA, the global ocean average temperature increased by around 0.77°C from 1970 to 2025, which is about 0.14°C per decade.

This year’s brewing ocean warmth – underpinned by El Niño – is likely to linger beyond the end of 2026 and could push global temperatures, in both the ocean and atmosphere, to new heights in 2027. According to Dr Leon Hermanson from the UK Met Office, “there is an El Niño predicted for the end of 2026, which increases the chances of the following year, 2027, being the next record-breaking year.”
