The recent bushfires in NSW are not in “mid winter”, where they occurred as suggested by many.
The bushfire season in mid-NSW always starts earlier than in southern Australia, with bushfires around Sydney and in the Blue Mountains historically occurring at this time of the year.
People forget how far north Sydney is (latitude), being closer to a sub-tropical than a temperate climate.
Every year when there are bushfires around Sydney in August or Sept, the cry goes out “Climate Change! Bushfires in mid-winter!”, while history and climatic zones are ignored.
On page 20 of the textbook, Bush Fire Control in Australia (1961), there is an excellent map of Australia showing the bushfire seasons. South-eastern Qld and central coastal NSW are clearly shown as having an occasional August / September fire season start.
It is worth noting that the weather varies from year to year, the diagram shows the average situation.
When you take notice of the date that this textbook was published (well over 50 years ago), these fires are nothing new. The intensity of the fires is increasing because of fuel loads and the drought in NSW will impact upon bushfire conditions.
