Australia's ski resorts are experiencing record-breaking July heat with temperatures soaring up to 12°C above average, raising concerns about the future of the ski season. The Bureau of Meteorology confirmed that Mount Hotham, Falls Creek, and Thredbo all set new July temperature records over the weekend, driven by a slow-moving high-pressure system and a warming climate.
Record-Breaking July Temperatures at Australian Ski Resorts
According to the Bureau of Meteorology, Mount Hotham's previous hottest July day of 8.7°C (set in 1994) was broken three times in just one month, peaking at 12°C on Sunday. Falls Creek also recorded its warmest July day and night, while Thredbo in New South Wales set a new July daytime record. Senior forecaster Angus Hines explained that a temperature inversion made it cooler at sea level than at higher altitudes, amplifying the heat at ski fields.
Impact on the 2024 Australian Ski Season
The heat wave follows a dry start to winter, leaving alpine areas with sporadic natural snowfall. Resorts have relied heavily on snow-making technology, but above-zero temperatures make even artificial snow difficult to maintain. The El Niño pattern in the tropical Pacific, combined with the bureau's long-range forecast, points to drier and warmer conditions for the rest of winter – a “bad combination” for snow.
Climate scientists have long warned that global heating will shrink Australia's ski season. The current records underscore that risk, with Hines noting that “this highlights the likely issues we will have with ski seasons into the future with a warming climate.”
Temperature Comparison: July Records vs Averages
| Resort | Previous July Record | New Record (2024) | Average July Max |
|---|---|---|---|
| Mount Hotham (VIC) | 8.7°C (1994) | 12.0°C | ~0°C |
| Falls Creek (VIC) | 9.1°C (1994) | 11.5°C | ~-1°C |
| Thredbo (NSW) | 10.2°C (1994) | 11.8°C | ~1°C |
Key Takeaways
- July 2024 shattered temperature records at major Australian ski resorts by up to 12°C above normal.
- A slow-moving high-pressure system and climate change are driving the heat.
- Natural snow is scarce, forcing resorts to rely on snow-making, which becomes inefficient in warm conditions.
- El Niño and long-range forecasts predict continued dry, warm weather – a bad combination for skiing.
- Climate scientists expect shorter, less reliable ski seasons in the future.
FAQ
Why are Australian ski resorts so hot in July 2024?
A slow-moving high-pressure system brought clear skies and descending dry air, causing a temperature inversion. Combined with the background warming from climate change, July temperatures climbed to 12°C above average.
How does this affect the ski season?
Resorts struggle to make and keep snow when temperatures stay above freezing. Many lifts remain closed, and natural snow is scarce. The season may be shortened or rely entirely on limited man-made snow.
What can ski resorts do to adapt?
Resorts invest in more efficient snow-making systems, groomers, and some diversify with summer attractions. However, long-term viability depends on global efforts to reduce emissions and slow climate change.
The outlook for Australia's ski fields remains uncertain. While forecasters predict a possible snow flurry this weekend, temperatures are expected to climb again early next week. Ski enthusiasts and the tourism industry alike are watching closely as the impacts of a warming climate become impossible to ignore.
