Temperature values coloured according to its difference from the long term average for this month. Outlined value mark highest and lowest values.
Maximum temperatures are measured over the 24 hours from 9 am on the day of measurement. Minimum temperatures are measured over the 24 hours to 9 am of the day of measurement. This was previously different to the official time standards and measured in degrees ºC (before 2018).
Rainfall is measured over 24 hours to 9am and recorded on that day. This is the same as the official time standard and measured in millimetres. Some measurements are not made at 9am and is adjusted based on the automatic record. For other variables see Notes below.
Notes
Based on Bureau of Meteorology Climate summaries (Copyright) of which some data was obtained from. From September 2017 the Bureau of Meteorology Climate summaries were expanded to provide data from official stations in and near the Greater Brisbane “Greater capital city Statistical Area” (GCCSA).
Data Copyright Ferny Grove Weather 2020, Produced 4/4/20. Data Checking has been carried out but errors may still be present and therefore there is no assurance of correctness. Corrections may be made at a later data if errors or deficiencies are found and/or improvements in data handling techniques are made, though data with major improvements may not be updated in this summary. Data measured with professional moderate accuracy equipment. This replaced non professional equipment of low accuracy with differences in the measured data. The new equipment measures the daily average wind speed and wind run about 40 % higher. Daily rainfall and grass minimum temperature is measured using non-professional equipment of moderate accuracy.
Site Commencement data is April 15 2009 except for daily rainfall which commenced on January 1 1987. Not all variables have been measured over the entire station record. Most variables are measured over a 24 hour period ending in the evening and over a 24 hour period from midnight effective October 5 2018. Maximum temperatures are measured over the 24 hours from 9 am on the day of measurement. Minimum temperatures are measured over the 24 hours to 9 am of the day of measurement. Rainfall is measured over 24 hours to 9am and recorded on that day. This is the same as the official time standard. Some rainfall measurements are not made at 9am and is adjusted based on the automatic record. Minimum Grass Temperature is measured over an approx. 12 hour period ending in the early morning. MSL refers to Mean Sea Level, which is the standard meteorological method of measuring air pressure reduced to sea level based on both elevation and temperature. Grass Minimum Depression is the difference of the grass minimum temperature from the air temperatures and is a positive value when the grass temperature is below the air temperature.
Up until March 9 2019 automatic records as Dew Point, Average Wind Speed, Dominant Wind Direction, Wind Run, Rain Rate and Hourly Rain are measured over a 24 hour period starting at midnight and recorded for that day. This started on the 6 October 2011. The automatic record is used for some data and also may be used if data is not available/ not suitable. From March 9 2019 the automatic record became the official record instead, simplifying this process. Until replaced on 5 October 2018 the temperature and humidity sensor is under exposed so minimum temperature and maximum humidity are incorrect and low accuracy rain gauge is used which are not used as the site’s official record. This data limitation does not apply to other measurements of temperatures, air pressure and humidity, wind gust, daily and monthly rainfall and rain days elsewhere in this summary which are recorded separately and form the official record for this site. The replacement equipment is sited in more exposed locations and therefore the limitations don’t apply, though the automatic daily rainfall doesn’t form the official data for the site.
Long term averages are based on all available long period past measurements from October 2019 whilst for non automatic rainfall is based on 1987 to 2017 average from the station record. Prior to this the long term average for Temperature, Relative Humidity and Air pressure is based on 2009 to 2015 average from the station record and wind speed is based on the 2010 to 2018 average from station record. Wind Run is 2011 to 2018 and Rain Rate and High Hourly Rain is 2011 to 2017.
The Fraction of monthly average expresses how much has fallen in respect to the long term average listed as a percentage. The decile ranking compares the rainfall total to the historical record for the site where the record is divided into 10 equal groups. Decile 1 is the lowest 10% of the record (10th percentile) and Decile 10 (90th percentile) is the highest 10% of the record. Decile 1 is considered “very low”, decile 2 and 3 “low”, decile 4 to 7 “average”, decile 8 and 9 “high” and decile 10 “very high”.
