Monitoring
To check for consistency with nearby official stations, the daily maximum and minimum temperatures from the AWS are routinely compared to the BoM AWS at Laverton RAAF, whilst the daily rainfall from the standard rain gauge is compared to the BoM AWS at Laverton RAAF and the Melbourne Water rain gauge at Hoppers Crossing.
Note: Tr indicates a rainfall amount of less than 0.1 mm (a trace of rain) and does not count towards the monthly rainfall total or the number of rain days.

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.
- Variation from long-term 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.
