Can I shower in a thunderstorm in Australia?

Of all the questions people ask about thunderstorm safety, this one keeps resurfacing — and for good reason. The answer from the Bureau of Meteorology (Australia’s official weather authority) is a firm no: showering during a thunderstorm can put you at serious risk.

Why showering is dangerous during a thunderstorm

• Lightning can travel through plumbing. When lightning strikes near a house, the electrical current can travel through metal pipes and water — both excellent conductors — and reach a person standing in the shower (Bureau of Meteorology (Australia’s official weather authority))
• The risk is not theoretical: cases of individuals being injured while showering during storms are documented globally, including in Australia
• The danger extends beyond showering — any activity that puts you in contact with plumbing or electrical wiring poses a risk

Other activities to avoid

• Using landline phones, because lightning can travel through phone lines
• Unplugging electrical appliances — the act of plugging or unplugging can cause a shock if lightning strikes nearby
• Washing dishes or touching any metal fixtures connected to plumbing

When it is safe to resume

• Wait at least 30 minutes after the last thunderclap before showering or using plumbing
• This 30-minute rule is recommended by safety authorities because lightning can strike from a distant storm cell

The pattern: preparation is the only way to stay safe without sacrificing comfort.

Which town in Australia gets the most thunderstorms?

For thunderstorm frequency, one Australian city stands well above the rest — and it is not Brisbane. Here is how the numbers stack up across the continent.

Thunderstorm frequency across Australian cities

• Darwin averages over 80 thunderstorm days per year, making it the most thunderstorm-prone city in Australia (Bureau of Meteorology (Australia’s official weather authority))
• Brisbane averages about 40 thunderstorm days annually — roughly half of Darwin’s count
• Sydney and Melbourne report significantly fewer, with around 25 and 10 thunderstorm days per year, respectively

The pattern: the closer to the tropics, the more thunderstorms. Australia’s thunderstorm frequency declines sharply southward and inland.

Why Darwin tops the list

• Darwin’s location in the tropical monsoon belt means warm, moist air from the Timor and Arafura seas fuels intense thunderstorm activity
• The city’s wet season (November to April) brings almost daily thunderstorms, often in the afternoon
• In contrast, Brisbane’s storm season runs September to March, driven by the subtropical climate

Brisbane’s thunderstorm climate

• Brisbane experiences severe thunderstorms less frequently than Darwin but with higher potential for damaging hail and wind
• The city’s 40 annual thunderstorm days place it among the more active Australian capital cities
• Brisbane recorded 1497.6 mm of rainfall in 2025, 145% of the long-term average (Bureau of Meteorology (Australia’s official weather authority))

What do you smell before lightning strikes?

If you have ever stepped outside just before a storm and noticed a sharp, metallic tang in the air, you are not imagining things. That scent has a name — and a scientific explanation.

The science behind the smell

• The smell is ozone (O₃), created when lightning splits oxygen molecules in the atmosphere
• Ozone has a sharp, metallic odor often described as similar to chlorine or burnt electrical wiring
• Because the scent can be carried ahead of the storm by wind, people sometimes detect it before seeing lightning or hearing thunder

Where the scent comes from

• When lightning strikes, its immense electrical energy breaks apart normal oxygen molecules (O₂) into individual oxygen atoms
• These free atoms then recombine with other O₂ molecules to form ozone (O₃) (Bureau of Meteorology (Australia’s official weather authority))
• Ozone is unstable and dissipates quickly, so the smell is fleeting — typically lasting only a few minutes

Other pre-storm signs

• A drop in barometric pressure, which can cause subtle discomfort in the ears
• Sudden shifts in wind direction and a rapid darkening of the sky
• Static electricity in the air — sometimes felt as hair standing on end

The catch: these signs can appear minutes before a storm hits, giving you a narrow window to take cover.

Is Cyclone Alfred actually going to hit Brisbane?

Cyclone Alfred formed in the Coral Sea in early 2026 and has been tracking toward Queensland, raising serious questions for Brisbane residents. Here is what the Bureau of Meteorology says.

Current status of Cyclone Alfred

• Cyclone Alfred is a real cyclone in the Coral Sea, monitored continuously by the Bureau of Meteorology (Bureau of Meteorology (Australia’s official weather authority))
• The system has triggered tropical cyclone watches and warnings for parts of the Queensland coast
• Residents in southeast Queensland, including Brisbane, are advised to stay alert and follow BOM updates

Exact path remains uncertain

• While forecast models show the system tracking toward Queensland, the exact trajectory remains unclear
• Whether it will directly hit Brisbane — or make landfall further north — depends on steering winds and sea surface temperatures
• The Bureau of Meteorology (Australia’s official weather authority) advises residents to monitor warnings and not to fixate on a single forecast cone

How to stay updated

• Check www.bom.gov.au and the BOM Weather app for the latest tropical cyclone advice
• Follow local emergency services and the Get Ready Queensland initiative for preparedness guidance
• Prepare an emergency kit with food, water, medications, and important documents

The implication: even if the cyclone stays offshore, excessive rain still demands preparation.

Where do the worst thunderstorms occur in the world?

Severe thunderstorms are a global phenomenon, but some regions experience them on a scale that dwarfs even Australia’s most active zones.

Global hotspots for severe thunderstorms

• Lake Maracaibo (Venezuela) holds the record for the highest lightning density on Earth — approximately 232 flashes per square kilometre per year (Bureau of Meteorology (Australia’s official weather authority))
• Tornado Alley in the United States (Texas to Nebraska) sees the most intense thunderstorm complexes, producing giant hail, destructive tornadoes, and extreme wind
• Northern India and Bangladesh also experience severe pre-monsoon thunderstorms that can trigger destructive winds and flooding

Australia’s place in the ranking

• Northern Australia, including Darwin, sees frequent and severe thunderstorms — Darwin averages over 80 thunderstorm days per year, comparable to some of the world’s most active zones
• Southeast Queensland, including Brisbane, ranks lower in frequency but is vulnerable to damaging hail and wind events
• Australia recorded a thunderstorm wind gust of 173 km/h in Armidale, NSW (2020), among the strongest recorded worldwide (Bureau of Meteorology (Australia’s official weather authority))

What makes a thunderstorm ‘worst’

• Hail size: giant hail over 5 cm in diameter — like the event forecast for Queensland on 31 October 2025 — can destroy roofs and cars (BOM YouTube Severe Weather Update 31 Oct 2025 (Australia’s official weather authority))
• Wind speed: gusts exceeding 90 km/h define a severe thunderstorm, but the most intense storms can generate winds over 150 km/h
• Lightning density: measured in flashes per square kilometre, with Lake Maracaibo as the extreme benchmark

The pattern: extreme thunderstorms share three measurable criteria, and Brisbane already meets two of them regularly.

How to prepare for severe thunderstorms in Brisbane

When a severe thunderstorm warning is issued for Brisbane, you need a plan — not panic. Here is a step-by-step guide built on official advice from the Bureau of Meteorology and Queensland authorities.

1. Monitor the BOM Thunderstorm Tracker for Southeast Queensland in real time (Bureau of Meteorology (Australia’s official weather authority))
2. Secure outdoor furniture, trampolines, and loose items that can become projectiles in high winds
3. Park vehicles under cover or away from trees
4. Charge mobile phones and backup power banks — power outages are common
5. Prepare an emergency kit: torch, batteries, first aid kit, bottled water, non-perishable food, medications
6. Know your evacuation route if you live in a flood-prone area
7. During the storm: stay indoors, away from windows, avoid using plumbing or electrical appliances
8. Never drive through floodwater — it is the leading cause of storm-related deaths in Australia
