Here's an old thread that hasn't been used for a couple of years. We could post reflections and observations on the change of season and thoughts on the coming season here.

I think that Autumn had arrived:

- We had a dry W-SW change come through.
- We had a mild, sunny day with Westerlies
- Deciduous trees are starting to turn
- It is looking decidedly Autumnal towards the end of the forecast period, with low teens minima and low 20s maxima for Sydney
- The Equinox has passed. Days are rapidly getting shorter
- The NRL season is well underway
- Reports of sub-zero minima in the highlands and possible flakes in the near future.
- Major heat is probably finished. No more 35+, maybe a couple more 30+. Sub 15 minima to become the rule away from the coast, few if any more 20+

I wonder if anyone has got stats on what percentage of the State has hit the Autumn Break which is '25mm or more over a period of 3 days'. I feel like it's another important feature of Autumn.

Autumn has most certainly arrived; although snowfall on Saturday & Sunday looks to be very marginal instead of a good chance for me now (due to some hefty precipitation loss from the forecast), it is still just as cold with 9° C and 8° C maximums, respectively.

Poplar and Birch are really showing their colours, amongst other trees.

Quite the contrary to last year, which seemed as if it were an "Indian Summer"—extended "summery" conditions pretty much from January to May...this year, summer halted when February halted, of which I like much better—more seasonal.

It a bit chilly in Sydney this morning after a clear night, the coldest since November, for example:

Sydney OH: 14.9. The last minimum this cold was December 24. The last colder minimum was November 25 (14.5)

Bankstown: 11.9. The last colder minimum was 11.8 on November 25.

Camden and Campbelltown dropped below 10.

A bit of cloud is rolling in now but I think it will soon burn off to another nice, sunny day, a bit cooler than yesterday.

The first taste of some cooler nights, 11.6 yesterday, about 12C this morning, and down to 10C on Sunday and Monday.
And then 10 to 25C is the the diurnal range, quite glorious.
Yep, the fist signs of autumn for sure.

One more week of getting home before dark.
Then a month later leaving for work in the dark.
And we descend into the period where I only see my house in daylight on the weekend.

I wish we could just stay on Daylight Saving time all year. I'd rather put up with the dark mornings and have more light in the evening to enjoy.

Many other places around the world are opting for permanent Daylight Saving time. The U.S states of California and Florida have voted for permanent Daylight time, although it hasn't been approved by Congress yet. Several north east States such as Massachusetts are considering it as well. With the E.U planning to eliminate yearly clock changes by 2021, some European countries are deciding whether to stay on permanent Daylight Time as well. Spain already has permanent Daylight Time.

Argentina also has permanent Daylight time. Take a look at Buenos Aires sunrise/sunset times and compare them to Sydney at about the same latitude.

Comparison:

Sydney earliest Sunrise - 6th December - 5:37 AM
Sydney latest sunset - 7th/8th January - 8:09 PM
Sydney latest sunrise - 6th April - 7:10 AM
Sydney earliest sunset - 11th/12th June - 4:52 PM

Buenos Aires earliest sunrise - 6th December - 5:33 AM
Buenos Aires latest sunset - 6th/7th January - 8:10 PM
Buenos Aires latest sunrise - 29th/30th June - 8:01 AM
Buenos Airest earliest sunset - 12th June - 5:49 PM

Sydney average solar noon - 11:55 AM (Standard Time) 12:55 (Daylight Time)

Buenos Aires average solar noon - 12:53 PM (ART Argentina Time all year)

https://www.timeanddate.com/worldclock/australia/sydney
https://www.timeanddate.com/worldclock/argentina/buenos-aires

I'd take Buenos Aires timezone over Sydney's any day of the week.

I like daylight saving in Summer but it does continue for too long. Not keen on it being dark at 7:00AM, 7:30 on overcast mornings like yesterday.

Around the Autumn solstice in Sydney each day is over two minutes shorter than the previous one. I would move the change to the weekend before the Autumn Equinox.

----

Well, a Winter style cold front sweeping eight through the state, with snow in the highlands and a cool, sunny day in Sydney with Westerlies. Definitely Autumn. Too bad the winds are going to turn South Easterly tomorrow, When that doesn't happen we'll know it's Winter.

Here's my first Autumn tree for the season, one in a front yard in Chatswood West that is always first to turn. Don't know the species:

Hard to say what type of tree it is Steve777, probably part of the maple tree family, have you got any close up pictures of the leaves?

Well this Autumn here the mushrooms have been popping up all over the place after the recent rains and not just your stock standard type either, plenty of the golden top varieties about.

That's an interesting observation haven't seen any mushrooms in these parts since the 2016 winter. Almost forgot they existed in these parts.

There have been a few mushrooms popping up around here after the rain.

-------
Autumn colours are advancing, although some deciduous trees are further along than others, with many still in full leaf. Here's a beautiful tree in West Pymble against the best backdrop, a clear blue sky. At 30-31 degrees, it was not quite Autumnal.

Trees starting to turn around here too Steve, although only just.
The recent heat seems to have slowed the rate of change.

Certainly much more advanced than last year though. Trees didn't start turning until late April, this year I saw the first hints of colour in mid march.

I see that the forecast for Sydney for the coming week after today is for temperatures close to and slightly below the seasonal average. Average min max forecast for April 10-15 compared to averages are:

Sydney OH: 14-23 c.f. 15-24 (1981-2010).
Parramatta : 12-23 c.f. 13-24.

The forecast has just been updated and is still going for 26 degrees with possible thunderstorms later today, with the possibility of thunderstorms again early next week.

Meanwhile, NAEFS is showing a warm signal for SE Australia for next week: NAEFS Apr 16-23

Pretty much nothing here apart from a few big drops. Looks like the southerly is now charging towards inland from Wattamolla. Hope it helps ignite something.

The change of season seems to be proceeding pretty much to schedule. Autumn colours are advancing, the beautiful deep purple tibouchinas are in full bloom and the cicadas have been silent for a month now. Blankets and jumpers have been retrieved from their Summer storage.

The following graph shows the progress of daily mean temperatures at Sydney Olympic Park, from early Summer until mid April. Forecasts have been used for April 13-19.



The dotted blue line shows daily readings, the red line shows a 7 day moving average while the orange line shows the 'long term' daily means - not that long, just 1996-2019, old and new sites combined.

As we can see, it was a hot Summer after a cool to average start, peaking in late January. It dipped below average in late February before bouncing back with some heat in early March. After that, we've had a fairly orderly cooldown, with temperatures now seeming to track close to average, in spite of ups and downs.

So what happens next? The chart seems to show that we're heading for an average (by today's standards cold) Winter. But with weather as with financial markets, graphs are of limited use in predicting the future.

After a cooler start, the change of season seems to have gone into reverse in the last little while.

Deciduous trees are still keeping to their timetable, however. Here's Little Digger Park in Roseville. It has a nice collection of Autumn trees at different stages, some still just starting to turn, one (out of frame) nearly bare and others in between:

Near the mid point of May, the season is still progressing, maybe a few weeks behind schedule:

Sydney Min, Max and anomalies for May 1-15 (average = 25% April - 75% May, OH 1981-2010):

Sydney OH :13.3 - 22.3 (+0.1 - +1.0)
Bankstown : 9.5 - 22.6 (-0.7 - +1.2)


There have been a couple of cold nights, but the coolest days have been average.

Maxima are expected to stay above average for at least a week, with warmer nights as well, so May could well end up significantly above average for Sydney.

It's been dry. At 14.6 mm, Sydney OH is tracking about 12% of the monthly average (all years). Bankstown, at 6.4 mm, is tracking 10% of its May average.

Progress on the season so far for Bankstown (min-max):

Feb 18-29; Mar 18-28; Apr 13-26: 1H May 10-23

------

The water dragons seem to have retired to their Winter lodgings. I saw one last week but none yesterday. They normally disappear after the first chilly days in May and don't return even if it warms up. I look forward to their return in August.

The Autumn displays are nearing their peak. Here are some trees in Richmond the other day:
