What does the fire danger rating actually mean?

Australia's Fire Danger Rating system has four action levels — Moderate, High, Extreme and Catastrophic — plus a no-rating day when conditions are benign. They describe how a fire would behave and how hard it would be to control, not how likely one is to start. At Catastrophic, the advice is to leave early; waiting to see what happens is the decision that gets people killed.

When is cyclone season in the Northern Territory?

Roughly November to April, matching the wet season. Most systems form in the Timor and Arafura Seas and affect the Top End coast. A cyclone watch means potential impact within about 48 hours and a warning means within 24, so a watch is the point to make decisions rather than the point to start reading about them.

Why does air quality matter in the dry season?

Because of smoke. Controlled and traditional burning runs through the dry across the Top End, and haze can sit over Darwin and the highways for days. It is usually a nuisance rather than a hazard, but it matters for anyone with asthma or a heart condition, and it flattens visibility for driving and photography.

How often does this page update?

Weather, marine and air-quality readings refresh whenever you load the page, so what you see is current at that moment. Alerts and closures change faster than any cached copy can follow, which is why they are links out rather than numbers reproduced here.

Live data is aggregated from open public APIs and refreshed every 5 minutes:

Weather, air, marine, UV: Open-Meteo (CC-BY 4.0, no API key)
ISS position: Where The ISS At
Moon phase & Milky Way: calculated locally (Meeus astronomical algorithms)
Bushfire, road, weather warnings: deep-linked to official NT government sources (no public API)

Estimates are directional. Always confirm safety-critical info with official sources before travel.

Reading the conditions

Fire danger describes behaviour, not likelihood

The rating answers “if a fire starts, how bad will it be and can it be controlled?” — not “will one start?”. Moderate through to Catastrophic each carry a different recommended action, and at the top of the scale the recommendation is to leave early rather than to prepare and wait. The NT’s fire season runs through the dry, when cured grass carries fire fast across open country.

Cyclone season overlaps the wet

From about November to April, systems forming in the Timor and Arafura Seas can affect the Top End coast. The distinction that matters is watch versus warning: a watch means possible impact within roughly 48 hours, a warning within 24. A watch is when to decide what you are doing, not when to start looking into it.

Smoke is a dry-season fact

Controlled and traditional burning runs through the dry, and haze can settle over Darwin and the highways for days at a time. For most people it is a nuisance and a photography problem; for anyone with asthma or a heart condition it is worth watching the air quality reading rather than the sky.
