Weather Factors Temperature & Humidity

🌡️ Danger zone: 25–30 °C. Fires in this temperature band burn an average of 49 ha — nearly 5× more than any other range. Only 52 fires fell here, but they account for 39% of all area burned.
💧 Low humidity drives damage. When relative humidity is 20–40%, total area burned jumps to 4,069 ha — more than double the next band. High humidity (60%+) nearly eliminates large fires.

Wind Analysis Speed vs fire behaviour

🌬️ Moderate wind (4–6 km/h) produces the largest fires — avg 15.7 ha vs 5.5 ha at high wind. Very strong winds may actually help firefighting teams contain blazes faster, or shift conditions unfavourably for fire spread.
