November 2016 weather report
Here is a slightly updated version of the report published in the Gazette. The main change is a decrease of 2mm in monthly rainfall - obviously something got duplicated in my updating. Sorry about that.
C and a minimum >10oC. If you wish to know more its here!'
For November this year we have one heat wave last 4 days. This is about normal.
An overall summary of the month would be that following a very wet Winter and and early Spring, and a very cool October, this month was pretty average in everything.
Rain
I regard 50mm of rain in a month as 'reasonable' and we just made it this month. The rain fell on 8 days spread through the month, although the last week was dry.
Note that the average shown here is for the past 9 years while that in the Gazette notice is for a 32 year period.
Whiskers Creek has run through the month, although getting a bit close to 'trickle' level by the 30th.
Temperatures
Looking at the month in detail there have been a series of warmings (shown by the chain of red boxes) followed by a sharp drop as a front comes through.
Average maximum temperature was very similar to last year and the long term average.
In much the same way that I have commented on frosts during the colder months I intend to cover the number of Heat Wave Days each month over the warmer period. In essence a Heat Wave is a period if 3 or more consecutive days with a maximum temperature >35oC and a minimum >10oC. If you wish to know more its here!'
For November this year we have one heat wave last 4 days. This is about normal.
The minimum temperature was well less than 2015, but almost exactly on average.
Humidity
When I first compiled a chart of daily readings for Relative Humidity at 3pm I was quite surprised at how many days were below my "reasonable"level of 40%. So I also downloaded the Bureau of Meteorology data for Canberra Airport.
It is clear that the two series are very similar. I then looked at longer term - 4 years of observations - average data which showed that the month was almost spot on the average, but somewhat less than 2015.
I believe the dryness does explain wide the wide brown land is justifying the brown element of the cliche.
... shows a breezy first half of the month after which the wind was much less evident.
The longer term picture continues to show a pattern of a higher average wind speed than in the past. (I cannot help but consider I have caused this by clearing the spider webs off the anemometer in April! Friction is a terrible thing!)
However again I consider the month to be rather average!

Wind.
Looking at the daily maximum gust ...... shows a breezy first half of the month after which the wind was much less evident.
