Fire Danger Index & BOM Fire Weather: How Australians Stay Safe
Discover how the Bureau of Meteorology’s Fire Danger Index and fire weather warnings can empower you, your family, or your fire crew to act early and confidently. This guide explains how to read the BOM’s fire weather info, what the Fire Danger Index really means, and how every Australian can plan, prepare, and respond—before, during, and after fire outbreaks.
Imagine waking up to the scent of smoke in the air or hearing the forecast call for “Catastrophic” fire danger. Whether you’re in the city, bush, or somewhere in between, knowing what to do next isn’t always simple. For families, renters, and rural properties, confusion or hesitation in those moments can make all the difference. For those on the frontline—volunteer or career—every update from the Bureau of Meteorology (BOM) shapes decisions, response, and the safety of your team.
This guide will help you understand BOM’s Fire Danger Index, use fire weather warnings for your local area, and feel more confident planning for fire season. You’ll find real examples, easy checklists, and tips for everyone—from householders and businesses to incident controllers and new recruits.
Along the way, we’ll show you how to access tools like the MaxWatt Generator for Power Outages, which can be a lifesaver during major fire events, especially when power is cut. Our aim is simple: reduce your uncertainty, make planning easier, and keep you, your family, or your crew one step ahead.
Understanding Fire Danger: The BOM’s Role in Fire Safety
Why is fire weather so important? The behaviour of bushfires in Australia is driven by temperature, humidity, wind, and how dry the land is. The BOM is Australia’s official source for fire weather forecasts. Every day, they issue warnings and a Fire Danger Rating that tells you—at a glance—how risky fire conditions are. For firefighters, it shapes how shifts are rostered, gear is checked, and when to ramp up patrols. For the public, it’s your early signal to act, not react.
But here’s the thing: lots of people misunderstand these ratings, or don’t know where to check them. Some wait for a siren or phone alert—by then, time is short. We’ll break down what the ratings mean, where to find the info, and how to use it to keep your household or fire crew safe.
What is the Fire Danger Index—and Why Should You Trust It?
The Fire Danger Index (FDI) is a number and rating used to show how dangerous fire conditions are in your area. Developed by Australia’s top fire scientists and the BOM, it takes into account temperature, humidity, wind, and how much fuel (dry grass, leaves, scrub) is on the ground. The higher the number, the more easily fires start and the faster they spread. You’ll usually see this on the news or BOM site as a rating (like “High”, “Extreme”, or “Catastrophic”), plus a colour band on the familiar Fire Danger Rating sign.
Where to Find Reliable Fire Weather Information—Fast
For any fire day, your best, up-to-date info is from:
- BOM Website Fire Weather: bom.gov.au/australia/warnings
- VicEmergency (or your state’s app): Push alerts, maps, and warnings—set up your location and notifications.
- ABC Emergency Radio: Most official warnings are repeated on the hour during emergencies.
Bookmark your state’s emergency info site—don’t rely on social media or word of mouth. In the middle of an outbreak, the official site is always updated first.
How to Read the Fire Danger Index: What Each Rating Means
No Rating / No Rating Issued: Conditions are low risk, but fires can still occur—always be aware of weather changes.
Moderate: Some fire risk, but most activities (mowing, BBQ, machinery) are safe if done with care.
High: Increased fire risk. Check restrictions, monitor conditions. If you see or smell smoke, act early.
Extreme: Fires can start easily, spread quickly, and be very dangerous. Most outdoor activities should be avoided; be ready to leave early if advised.
Catastrophic / Code Red: These are the worst conditions. For the public: leaving early is the safest option. For fire crews: every resource is on alert; fatigue management, logistics, and rapid response plans are critical.
Preparation: What to Do When the Fire Danger Index Rises
Preparation is your best defense. The BOM and emergency services give you hours (often days) of warning before the worst fire conditions hit. But action must be early. Here’s how:
- Check the fire rating each morning in fire season—set a reminder on your phone.
- Clear leaves, dry grass, and rubbish from gutters and around buildings.
- Move flammable items (mats, woodpiles, gas bottles) away from the house.
- Prepare your emergency kit and make sure everyone knows where it is.
- Review your exit routes. If your area is high risk, plan to leave early.
- Read the BOM fire weather briefing as a team. Note wind changes, dew point, and FDI peaks.
- Check all vehicles, gear, and communications—no shortcuts on Catastrophic days.
- Assign roles for traffic management, logistics, and crew support in advance.
- Discuss fatigue plans, breaks, and welfare—long days mean longer nights.
- Share a quick mental health check-in; fire season is tough on everyone.
Don’t wait for sirens. If you feel unsafe, trust your gut and act early—evacuate, call your neighbour, or text your brigade leader. Early action saves lives.
Response: What to Do If a Fire Breaks Out Near You
You hear a warning or see smoke—now what? Your first job is to stay calm and focus on what you can control.
- Check your emergency plan and listen for updates on ABC Radio or the BOM site.
- Evacuate early if advised—don’t wait for the last minute.
- If you stay: block gaps with wet towels, fill baths/sinks with water, move everyone (and pets) to a safer part of the house.
- Keep phone, torch, and battery-powered radio close.
For Firefighters & Incident Controllers:
- Brief all crews on fireground weather, wind shifts, and local risks (e.g., topography, assets).
- Keep comms open—share weather changes instantly with all teams.
- Use the FDI to decide resource priorities and safety margins—err on the side of caution.
- Ensure relief, rehab, and welfare for all members—fatigue and heat exhaustion hit fast.
Never drive through smoke or fire. Most fatalities occur when people wait too long or attempt to outrun a fast-moving blaze by car.
Recovery: What Happens After Fire—And What Comes Next?
After fire comes shock, relief, or heartbreak. But recovery is a process, and it’s okay to feel overwhelmed. BOM and state agencies will issue “all clear” messages once risks have passed. Before returning home, check official advice on safety (powerlines, gas leaks, structural damage).
- Don’t rush home. Wait for emergency services to confirm your area is safe.
- Contact your insurer and take photos before cleaning up.
- Check on neighbours, especially elderly or those living alone.
- Access support: Services Australia – Disaster Recovery, or your state’s recovery hub.
- Look after yourself and your family—seek mental health support if you need it.
Planning & Packing for Fire Season: Be Ready, Not Rushed
- Emergency plan (printed and digital)
- First aid kit, masks, and gloves
- 3+ days of food and water for people and pets
- Essential medicines and scripts
- Chargers, battery packs, and a torch
- Important documents (ID, insurance, contacts)
- Clothes, blankets, and sturdy shoes
- Pet carriers, leads, food, and water
- Discuss your fire plan with your landlord, home care, or support team.
- Know who will help evacuate pets, and have a backup.
- Keep mobility aids, hearing aids, or glasses in a grab bag by the door.
- Let your local CFA or fire service know if you’ll need extra assistance.
- Prepare spare keys and let a friend or neighbour know your plan.
Common Mistakes—and How to Avoid Them
- Waiting too long to act—especially after receiving a warning or seeing smoke.
- Assuming “the CFA or fireys will save us”—fire moves faster than trucks on severe days.
- Not checking the fire danger rating daily, especially on holidays or weekends.
- Relying on a single source for updates—always have radio, app, and website options.
- Leaving pets unprepared—pack their needs in your grab bag.
- Not reviewing or practicing your plan as a family or crew.
- For crews: skipping gear checks, not hydrating, or ignoring fatigue warnings.
Remember: most “close calls” start with a small mistake. Be kind to yourself and others—just review, reset, and learn for next time.

Frequently Asked Questions
Go to the BOM Fire Weather site, use your state’s emergency app (like VicEmergency), or listen to local ABC radio for updates. Always check in the morning and before heading out.
Catastrophic (or Code Red) means the highest risk of fast, uncontrollable fires. The safest option is always to leave high-risk areas early, even before a fire is close.
On High, Extreme, or Catastrophic days, many outdoor activities (like BBQs, mowers, welders) are restricted. Check your state’s fire ban rules before using anything that sparks.
BOM fire weather is the foundation, but local crews use “on the ground” checks—wind, dew, fuel loads, topography—to adjust tactics. Always combine official forecasts with local knowledge and experience.
Read the fire weather briefing before your shift, ask senior members about local risks, and always check the FDI before heading out. If in doubt, ask for a quick “weather and tactics” chat before roll-out.
Review your fire plan tonight, chat with your family or team, and bookmark the BOM Fire Weather page. You’ve got this.
