About this table

  • These observations have not been quality controlled.
  • Different stations report at different time intervals, ranging from half hourly to twice daily.
  • All observations including locations outside of WA are shown in local time.
  • 'Temp' is Temperature.
  • 'App Temp' is the Steadman Apparent Temperature in shade. The Apparent Temperature is an estimation of what the temperature 'feels like' to an appropriately dressed adult. Direct exposure to the afternoon sun would add as much as 8°C to the App Temp. About Thermal Comfort Observations
  • Delta-T is Wet Bulb Depression (Air Temperature - Wet Bulb Temperature). About Delta-T
  • Wind 'Dir' is the direction the wind comes from, reported to 16 points of the compass.
  • Wind observations are a 10-minute average from the standard height of 10 metres.
  • Wind speed is a 10 minute average speed in knots.
  • The wind gust is measured over 3 seconds.
  • 'Press' is Mean Sea Level Pressure. The correction from station level pressure to mean sea level pressure may sometimes use the conditions specified by the International Standard Atmosphere in the conversion process, rather than the conditions at the station at the time of the observation.
  • 'Trace' is a trace (<0.1mm) of rainfall.
  • '-' indicates that no data is available at that time.
