Weather influences

A high pressure system shifted eastwards into New South Wales on the 1st and maintained a ridge over eastern Queensland.
On the 2nd a high pressure system shifted further east over the Tasman Sea with the ridge along the east Queensland coast easing.
A surface trough shifted eastwards across the state extending unstable conditions with its passage on the 3rd.
On the 4th a trough cleared off the east Queensland coast early in the day allowing a high pressure system over southern Western Australia to extend a ridge over the state and a cool, dry air mass across most of the state.
A high pressure system over central Australia on the 5th, moving into east Queensland on the 6th extended a strengthening ridge and a cool, dry air mass across the state.
On the 7th the high pressure system moved into the Tasman Sea that extended a weakening ridge over eastern Queensland and a weak pressure gradient in the region.
The high pressure system shifted further east over the Tasman Sea on the 8th that extended a weakening ridge along the east Queensland coast. A strong cold front swept across central and southern inland of the state quickly that brought unstable conditions over inland parts of the region.
A cold front shifted eastwards off the east Queensland coast in the morning of the 9th that extended to a complex low pressure system in south-eastern Australia. This extended a dry westerly airflow over southern Queensland behind the trough. A high pressure system in Great Australian Bight extended a ridge in the wake of the front. This brought unstable conditions with the front.
On the 10th a deep low pressure system shifting east over New South Wales extended cool and dry winds in southern Queensland. A high pressure system in the Tasman Sea otherwise extended a weak ridge across the state.
On the 11th a high pressure system over central Australia extended a weak ridge over the state, while a deep low pressure system shifting eastwards over New South Wales and into the Tasman Sea extended a cool and dry air mass over southern Queensland.
The high pressure system shifted eastwards into the Tasman Sea on the 12th that extended a weak ridge over the state. A low pressure system shifting eastwards over the Tasman Sea maintained dry westerly flow over southern Queensland.
On the 13th a weak ridge extended over the state with stable conditions over most of the state from a high pressure system over eastern Australia.
On the 14th the weak pressure gradient persisted as moisture starts to return over eastern Queensland.
A weak ridge extended over eastern Queensland on the 15th with some moist onshore flow.
On the 16th a weak ridge extended over eastern Queensland. A cold front shifted eastwards over inland and central parts of the state, but with stable conditions in the region.
The 17th saw a trough shift eastwards and off the east Queensland coast early in the day and brought some instability. A large high pressure system over the Great Australian Bight extended a strong ridge and cool and dry air mass across southern and central Queensland in the wake of the trough.
On the 18th the high pressure system maintained the cool and dry air mass across most of the state. A deep low pressure system in the Tasman Sea directed cool south-westerly flow over southern Queensland.
On the 19th the high pressure system remained in the Great Australian Bight and continued to direct a cool and dry air mass over most of the state. A deep low pressure system shifted north-eastwards over the Tasman Sea and combined with the ridge to extend moderate to fresh and gusty west to south-west flow in the region.
The high pressure system shifted eastwards over south-eastern Australia and directed a cool and dry air mass across the state on the 20th and 21st. A low pressure system shifting eastwards over the Tasman Sea extended a southerly swell along the southern Queensland coast.
On the 22nd a high pressure system shifted eastwards over the Tasman Sea extending a ridge over most of the state and directing a stable air mass across most of the state.
A high pressure system in the Tasman Sea extended a ridge over the state on the 23rd with some moist onshore flow.
On the 24th a weakening ridge extended over the east of the state as a high pressure system shifts east over the Tasman Sea. A trough and cold front moved eastwards over southern Queensland with an associated cloud band extending over the west and south of the state. This extended instability into the region during the evening.
The 25th saw a cold front over central and southeast parts of the state to shift eastwards extending a cloud band from the northwest to the southeast of the state. This brought moisture and instability in the region.
A trough and upper level trough that brought instability shifted eastwards off the east Queensland coast later in the day on the 26th while the upper trough lingers further inland. A high pressure system extended a ridge in the wake of the trough and a cool and dry air mass.
On the 27th a high pressure system over southeast Australia extended a firm ridge and an stable air mass over much the state. An upper level trough shifted eastwards over the south of the state.
A high pressure system moving east over south-eastern Australia extended a firm ridge over the state with some instability along the exposed east coast on the 28th.
The high pressure system moved into the Tasman Sea on the 29th extending moist onshore flow along the east Queensland coast before the ridge started to weaken on the 30th while the onshore flow persists.

Temperature values coloured according to its difference from the long-term average for this month. Outlined value mark highest and lowest values.

Temperature colour scale

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 temperature scale

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 2021, Produced 2/10/21. 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”.
