Most of first 18 days of the month saw above average daytime temperatures. Following the passage of a front there were cool nights between the 22nd and 26th, but was partially affected by persistent overnight breezes that slowed the falling in the temperature during much of these nights.

In June rainfall was slightly below average, with a total of 45.5 mm (73.5% of the long term average). This follows below average rainfall that occurred in the previous 2 months in autumn. Year to date rainfall however remains above average at 14 % above the long term average and the highest since 2015. During the middle of the month were showers with mostly light falls. A shower on the 14th brought brief heavy falls of 5.8 mm in 3 minutes. With the passage of the trough that preceded the cool nights later in the month were further light showers before some light showers returned at the end of the month.

Long period rainfall totals over the shorter time-spans improved slightly due to the near median rainfall in June but the longer time-spans have remained the same or deteriorated further given past months has seen below average rainfall totals. 6 monthly rainfall remained above average given the significant or near average rainfall was experienced in February and March. However 9 monthly to 48 monthly rainfall remain well below average with the greatest being 18 monthly rainfall at 285.5 mm below average.

Autumn 2020 weather review

The review of the weather at Ferny Grove during autumn 2020 is now available.

Autumn 2020 brought close to average overnight temperatures, whilst daytime temperature were 1 ºC above average. The mean daytime temperature was very similar to autumn in 2019 while the overnight temperatures were nearly 1 ºC lower. The lowest overnight temperature during the season of 9 ºC was the highest on record for autumn. Between the 22 May and 24 May were cool to cold days that brought a record low daily maximum temperature of 16 ºC on the 23 May.

After close to average rainfall during March, the following months in April and May saw low rainfall totals. The rainfall total for May (12.1 mm) was the lowest since 2004, and 70 % of the rainfall in May occurred on the 21st due to the passage of the trough followed by a cold and dry air mass brought by a complex low pressure over southern Australia. The highest hourly rainfall total in March was a new record high when a severe thunderstorm on 6 March brought 40 mm in 30 minutes with very heavy rainfall. The total for the season was the lowest since 2016 with a total of 168 mm (52.3 % of the long term average).

By the end of the season long period rainfall totals fell with the low rainfall totals during much of the season. Anomalies from the long term average were in the negative for all periods between 9 and 48 months, with the lowest being 18 month rainfall being 368 mm below average. However, because significant rain was experienced at the start of the year 6 monthly rainfall is still above average (60.5 mm above average and in the highest 20% of records).

May 2020 weather review

The review of the weather at Ferny Grove during May 2020 is now available.

May 2020 experienced near average overnight and daytime temperatures. Daytime temperatures were 1 ºC above average during the month until a number of cool to cold days between the 22nd and 24th reduced the mean maximum temperature to near average.

In May very little rainfall was observed during the month, with a total of 12.1 mm (12% of the long term average) and the lowest for May since 2004. 70 % of the rainfall occurred on the 21st due to the passage of the trough followed by a cold and dry air mass brought by a complex low pressure over southern Australia. Rainfall otherwise during the month was comprised of light showers with low daily rainfall totals, mostly in the middle of the month.

Long period rainfall totals also continued to reduce further in May followed continued below average rainfall during autumn. Anomalies from the long term average reduced further as a result with 9 monthly to 48 monthly below average, with the lowest being 18 month rainfall being 368 mm. But given that significant rainfall was experienced at the start of the year, 6 monthly rainfall is still above average (60.5 mm above average and in the highest 20% of records).

May 2020 website additions

Several new pages are now available on the website using data retrieved from a database of the weather station data. These new pages are:

  • Past Month Graphs that graphically shows the data for the various parameters at 5 minute intervals for the past 30 days. This is functionally very similar to the Recent Data graphs which shows the last 7 days but at a 1 minute resolution.
  • Top 10 Records shows the Top 10 extremes measured at this station for various parameters.
  • Recent Extremes Since looks at some of the extremes for today and yesterday and compared that to the all-time extreme records and in the past for the current month by showing the last time these extremes was higher or lower.

Various other modifications that has been made and are summarised as:

  • Some bugs/ corrections with the graphing have been made with the major issues being the home page real-time graph not updating with new data after the page loads and the “Daily Temperatures” and “Daily Rainfall” graphs showing dates into the future.
  • The introduction of Past Month Graphs replaced a previously available page to show data in case of system interruptions. That was a non database data source and so this removal brought a reduction in bandwidth usage.
  • Backend improvements to the file structure, updating J Query and consolidating the graphing to use a single source of styling
  • The Seabreeze Forecast was fixed after it stopped working on the Forecasts and Observations page.
  • The station status showing the station online or off-line on the home page and similarly on the System Status have been improved. It now handles instances when the station goes off-line when issues occur or for maintenance in a more robust manner. It does that by now making these checks on all uploaded data. It also now indicates whether interruptions or going off-line is a partial issue affecting all data updating on the website or whether is only affecting some of the data.

Welcome to the blog

Today is one year to the day that this website was launched. Just over 2000 page views have been made from at least 1200 visits in the last year.

The Ferny Grove Weather website was created as a personal project to replace the existing website that was well over-due for a revamp and for the current weather data to be available online in real-time.

I would like to thank everyone for visiting this website during this time, many of who have have showed interest by returning numerous times or by providing feedback on how you like the website. It was not anticipated that this website would continue to see people visiting this website in this way. In fact during active weather events visitor activity of the number of people who visit the site would significantly increase.

I offer this weather data without warranty in the hope that it is useful. There are many people publishing weather station data through international personal weather station networks. However there are very few that run independent weather websites in our region of south east Queensland. The benefit of these websites is that they measure weather data at locations without official stations nearby with the freedom to present the data how we like to show it.

I am starting up this blog given this interest and primarily as a way to communicate that new content is available and content that is under testing/ or trial.  There is much planned to add to what we already have available involving learning different processes to deliver that data and that will take time to achieve. Additionally I would like to see this as a way to inform on how this data is produced and published if there is appetite for this information.

Please tell us if you have thoughts on what you information you would like to see on this blog.
