Recent developments in the Pacific are putting El Niño back in the spotlight, raising questions about what the months ahead could mean for Australia.
Recent observations reported by Weatherzone show unusually strong signals in both the ocean and atmosphere. In July 2026, subsurface heat in the tropical Pacific reached its highest level for any month in records dating back to 1979, while the Southern Oscillation Index (SOI) averaged -29.1 — the most negative July value on record.
But with Australia only entering spring, the most useful question isn’t simply how hot could summer become?
It’s what can we do now to prepare?
Spring provides workplaces, sporting organisations and individuals with an important window to review their heat management strategies, prepare cooling equipment and make changes before Australia’s hottest months arrive.
What Could El Niño Mean for Australia?
El Niño occurs when the central and eastern tropical Pacific Ocean becomes unusually warm and atmospheric circulation across the Pacific changes.
For Australia, past El Niño events have often been associated with reduced winter and spring rainfall, particularly across eastern Australia, as well as warmer daytime temperatures across southern regions.
Current conditions do not guarantee that every part of Australia will experience extreme heat. Every El Niño is different, and other climate influences also affect Australia’s weather.
What El Niño does provide, however, is another reason to take the coming warmer months seriously.
Rather than waiting to see exactly how summer develops, spring gives Australians an opportunity to prepare early.
Why Spring Is the Right Time to Prepare for Summer Heat
Heat management often becomes a priority only once temperatures are already high.
For workplaces, this can mean reviewing procedures after workers are already experiencing difficult conditions. Sporting organisations may begin adjusting training only after athletes start struggling with the heat. Individuals often purchase cooling equipment once a heatwave has already arrived.
Spring allows for a different approach.
Preparing now means there is time to:
- Review heat management plans
- Identify workers or activities with greater heat exposure
- Prepare hot-weather training protocols
- Check hydration and shaded rest facilities
- Organise cooling equipment
- Educate teams about recognising heat stress
- Test strategies before extreme conditions arrive
Heat preparedness should begin before heat becomes a problem.
Recent heatwaves have also shown why preparation needs to happen before extreme conditions arrive. Learn more about what heatwaves can teach us about heat preparedness.
5 Ways Workplaces Can Prepare This Spring
Australian workplaces with employees exposed to outdoor heat, machinery, protective clothing or physically demanding environments can use spring to prepare for the months ahead.
1. Review Your Heat Management Plan
Assess how your organisation currently manages hot-weather work.
Consider workload, rest breaks, access to shade, hydration, protective clothing and procedures for responding to heat-related symptoms.
Spring provides time to identify gaps before conditions become more demanding.
2. Identify High-Risk Tasks
Not every worker experiences heat in the same way.
Physically demanding work, direct sunlight, radiant heat, poor ventilation and protective equipment can all increase thermal strain.
Identifying these activities now makes it easier to develop appropriate controls before summer.
3. Plan Work Around Hotter Conditions
Where possible, consider whether physically demanding tasks can be scheduled during cooler periods of the day when temperatures rise.
Work-rest schedules and access to cooler recovery areas should also form part of the plan.
4. Prepare Hydration and Recovery Areas
Ensure drinking water is readily available and workers have appropriate opportunities to rest and rehydrate.
Hydration is essential, but it should be used alongside other heat management measures rather than treated as the only solution.
5. Have Personal Cooling Ready Before Summer
Spring is also an opportunity to introduce and test wearable cooling before it is urgently needed.
Arctic Heat cooling vests provide portable, wearable cooling and can form part of a broader heat management strategy alongside hydration, shade, rest and appropriate scheduling.
Having cooling equipment ready during spring means workers can become familiar with its use before Australia’s hottest conditions arrive.
How Can Athletes Prepare During Spring?
Spring is also an important transition period for Australian sport.
As temperatures begin to rise, athletes and coaches can gradually introduce hot-weather strategies rather than waiting for the first extreme day.
Preparation can include:
- Moving training away from the hottest periods
- Reviewing hydration strategies
- Monitoring weather conditions
- Providing shaded recovery areas
- Introducing pre-cooling
- Using cooling during training breaks
- Incorporating post-exercise cooling
Arctic Heat cooling vests can be incorporated before activity, between training sessions or events, and during recovery.
Testing these strategies during spring allows athletes and teams to establish routines before hotter summer conditions arrive.

Why Cooling Vests Should Be Prepared Before They’re Needed
A cooling vest is most useful when it’s already available.
Waiting until a heatwave has arrived can turn heat management into a reactive process.
Preparing Arctic Heat cooling vests during spring allows workplaces and sporting organisations to determine:
- Who may benefit from using them
- When they should be incorporated
- How they fit alongside existing heat controls
- How they should be activated and stored
- How many may be required during hotter conditions
For Arctic Heat cooling vests, activation follows a simple process:
Soak. Dry. Freeze. Wear.
Once prepared, the vest provides a practical, wearable cooling option without requiring batteries or continuous electrical power.
Spring Preparation Can Make Summer Easier
No one can predict exactly what conditions every Australian community will experience this summer.
That’s precisely why preparation matters.
El Niño provides a timely reminder that heat management shouldn’t begin with the first heatwave warning. Spring is the opportunity to prepare while there is still time to plan, test and adapt.
For businesses, that means reviewing heat management procedures.
For sporting organisations, it means preparing athletes for hotter training and competition.
For individuals, it means considering how to manage prolonged heat exposure before temperatures climb.
Don’t wait for summer to start preparing for summer.
Use spring to get ahead of the heat.
