Notes
- Unless otherwise stated, temperature is given in degrees Celsius (° C), rainfall in millimetres (mm) and pressure in hectopascals (hPa).
- Our long-term averages and station records are based on all available data since 1 April 2017. All annual data are based on complete calendar years commencing in 2018.
- If a station record is equalled, the record passes to the most recent date to conform to standard BoM practice.
- Anomoly is the difference between the recorded value and the long-term monthly average.
- For most meteorological elements, the mean is the standard measure of the average.
- For rainfall, the median is the preferred measure of the average, particularly if there is a small volume of data.
- Refer to our observing program for details about the observation period for each element and how the data are stored.
