New Zealand Seasonal Fire Danger Outlooks
Each summer Scion prepares fire danger outlooks for Fire and Emergency New Zealand. Outlooks are produced each month over the fire season for both of the North and South Islands. The purpose of these monthly outlooks provide a heads up on progressing fire danger conditions as we transition from spring to summer, and then into autumn.
The reports enable fire agencies to prepare in advance for changes in fire danger conditions in their area. They are used as a prompt for local and regional discussions on fire potential (which depends on a number of other factors in addition to weather and climate effects, including fuel conditions (i.e. grass curing), risk of ignitions, recent fire history and fire management resource availability).
An outlook is produced for each Island monthly. The preparation of each report includes analysing current and historical fire danger conditions, interpreting NIWA and MetService climate outlooks, and determining likely impacts on the potential for wildfires in different regions of the country.
Comparisons of fire danger for individual indicator stations in different regions of the country are also available as graphs. Trends for the Drought Code (DC), Buildup Index (BUI) and Cumulative Daily Severity Rating (CDSR) are provided for all stations in PDF format.
The more detailed regional graphs highlight where the BUI, DC and CDSR values sit in comparison with previous fire seasons. The graphs display:
- The current fire season (bold red line)
- The long-term average (bold black line)
- The range of historical max and min values (light grey shaded area)
- Similar fire season years based on ENSO status - which for the current 2019/20 fire season is 2014/15.
