Thunderstorm asthma occurs when certain weather conditions cause grass pollen to break into smaller particles that can be inhaled more deeply into the airways and may trigger asthma symptoms. It is more likely during spring in NSW, when grass pollen levels rise, and storm activity increases. Understanding your risk and preparing ahead of time can help you respond calmly if symptoms occur.
Key Takeaways
- Thunderstorm asthma is linked to high pollen levels combined with certain storm conditions.
- People with asthma, hay fever or pollen sensitivity are more likely to be affected.
- Preparation before spring can help you manage risk
- Symptoms include wheezing, coughing, chest tightness and shortness of breath
- Severe or worsening breathing difficulty needs urgent medical attention
What Is Thunderstorm Asthma?
Thunderstorm asthma is a type of asthma flare-up linked to high pollen levels and specific weather conditions, particularly thunderstorms during spring. During certain storms, strong winds and humidity can cause pollen grains to break into smaller particles. These smaller particles can travel further and may be more likely to reach the lower airways than whole pollen grains.
For people who are sensitive to grass pollen, this can trigger asthma symptoms, sometimes suddenly and in people who have not previously had a diagnosis of asthma.
Why Does Spring Increase Thunderstorm Asthma Risk in NSW?
In many parts of NSW, spring and early summer can bring higher grass pollen levels alongside weather conditions that may increase thunderstorm asthma risk. This combination creates the conditions under which thunderstorm asthma events are more likely to occur.
Factors that contribute to higher risk during this period include:
- Rising grass pollen counts through spring
- Storm fronts that can disperse fine pollen particles over wide areas
- Humid, windy conditions common before and during storms
- Increased time spent outdoors as weather warms
Being aware of local pollen forecasts during spring can help people who are sensitive to pollen plan their activities around higher-risk days.
Who Is More Likely to Experience Thunderstorm Asthma Symptoms?
Some groups are more likely to be affected during thunderstorm asthma events than others. These include:
- People with an existing asthma diagnosis
- People with hay fever or allergic rhinitis
- People with known grass pollen sensitivity
- Children with allergic conditions or a family history of asthma
- People who have experienced seasonal breathing symptoms in the past, even without a formal asthma diagnosis
Having one or more of these factors does not guarantee that symptoms will occur, but it is useful context for understanding personal risk during spring.
What Symptoms Should You Watch For?
Thunderstorm asthma symptoms can develop quickly, sometimes within a short time of exposure to affected outdoor air. Symptoms to watch for include:
- Wheezing
- Persistent coughing
- Chest tightness
- Shortness of breath
- Difficulty breathing
Symptoms can vary between individuals in both severity and how quickly they appear. Some people may notice mild symptoms, while others experience a more significant flare-up.
How Can You Prepare for Thunderstorm Asthma This Spring?
Preparation before and during spring pollen season can help you respond calmly if symptoms occur.
Before storm season:
- Review your current asthma management plan with your GP
- Understand your personal triggers, particularly grass pollen
- Keep prescribed reliever medicine available and check it has not expired
- Monitor local pollen forecasts during spring
During high pollen or storm-warning weather:
- Follow your existing asthma action plan
- Consider reducing outdoor exposure if pollen counts are high and a storm is forecast
- Keep windows closed during high pollen periods where practical
- Monitor for any changes in your breathing and act on your action plan early

When Should You Speak With a GP About Asthma Symptoms?
Regular review of your asthma management is worthwhile, particularly heading into spring. Speak with a GP if:
- Your asthma symptoms are becoming more frequent
- Your usual asthma control has changed
- You have questions or concerns about your current medicines
- Seasonal symptoms are starting to affect your daily activities
- You have never been formally assessed for asthma but experience seasonal breathing symptoms
A GP assessment for breathing symptoms at Huntlee Healthcare can help review your history, current management and whether any adjustments may be appropriate before pollen season peaks.
What Happens During an Asthma Review With a GP?
An asthma review is a straightforward and practical process. During the appointment, a GP may:
- Discuss your current symptoms and how often they occur
- Review your medical history and any known triggers
- Review your current medicines and asthma action plan
- Discuss whether further testing or management adjustments may be appropriate
This kind of review is particularly useful before spring if your symptoms have changed since your last check, or if you have never had a formal asthma review despite experiencing seasonal breathing symptoms.
When Do Breathing Symptoms Need Urgent Care?
Most thunderstorm asthma symptoms can be managed with an existing asthma action plan and prescribed reliever medicine. However, some symptoms need urgent medical attention.
Seek urgent medical care or call 000 if breathing difficulty is severe, symptoms are rapidly worsening, or you cannot speak comfortably because of breathlessness.
Do not wait for a routine GP appointment in these situations.
