June Weather Report

Dry.  If you need more than that, read on.

Here is the Gazette format summary, with slight changes to the rainfall.  Note that this was the driest June since recording here began in 1984

Precipitation

I normally start with a heading of rain, but we didn't have any.  The 1.6mm shown above came through 8 mornings in which my weather station condensed 0.2mm of fog.  In both the next two charts the value for June 2017 is so small as to be almost invisible.

Another way of looking at the depressing state of  hydration is to compare the "year to date" totals after each month of 2017.
Thus far in 2017 we are up to 51.3% of average - a lower percentage than at the end of March.

Temperature

 A cool month (as might be expected for the first month of official Winter.

 Looking at the long term maximum temperatures we were a bit above average and last year.
 The average minimum temperature was a tad above 0oC whereas the long term "average average" is slightly blow that value.
 It is interesting to look at the average minimum temperature for the month over the period for which we have records.  (Note that minimum temperatures are very dependent on elevation of sites: a hilltop in Cox Place records higher temperatures than our house and the Plain is much colder.)
I have played with trend lines on this chart and none of the options appear statistically significant and the direction varies quite a bit according to the type of trend chosen.

It was a bit frostier than average, as would be expected with effectively dry weather.  Air frost is a minimum below  0oC ...
 .. while a ground frost is below  2oC.

 Humidity

A mid-range month.  None of my 3pm readings were below 40% rH and none above 80%
 As might be expected this is well below the average value for the month and the value for the very soggy June last year.

 Wind

Subject to my usual caveats about the poor siting of my weather station for measuring wind, the month was quite low for breeze.  This is to be expected with a big fat high-pressure system sitting over the country!

Insects from pine trees

Image
This afternoon (13/1/2015) we were looking out of our sunroom and noticed a strange bit of mist.  On getting my binoculars on the case I found it to be a cloud of tens of thousand of insects.  They appeared with naked eye to be flying away, but with binoculars I thought they were circling. Here are some images In the second one it may be possible to see there are two streams coming from the top of each tree. There was a loud buzzing noise but that could just be several thousand wings. Earlier in the day Frances had been to some nearby willows and they were infested with many little black soft bodied insects.  Perhaps they shifted to the pines and were swarming? Help!! Any information welcome. A colleague, from Wamboin, had noticed a similat phenomenon, but involvng eucalypts rather than pines!  Here are the photos he took with his phone. I have consulted some expert friends.   Their responses were: I would have gone for chironomids. I rec...

A tour of the West (part 1)

Image
A friend from my time in the UN sent me some photos of her family trip along Route 66.  They did this is a large camperwagon rather than a Chevy Corvette (apparently the kids jacked up about being offered a trip in the trunk).  It seems to have been a very good trip for them and most interesting to see their photos.  It was also educational for me, as I found out the German for rocking chair (schaukelstuhl, since you ask). They did 7200 miles in 30 days - a pretty serious bit of distance. This made me think of the trips we did in 1981 when living in Denver.  Frances initiated that idea by getting a book about the National Parks of the West  and marking interesting places.  I then worked out a route on a Rand-McNally Road Atlas (GPS was unknown then  - as were iPhones, personal computers and the internet).  From memory, taking nearly the whole Summer school holidays we covered about 10,000 miles in 70 days.  Here, approximately,  are ...

Maslins beach rules

Image
Anyone who was in Adelaide in the 1970s will be having a good nudge nudge at that title.  However the beach is really nice even though it is the haunt (in Summer ) of naked people.  (As an aside one of the 'van park staff was talking to some other guests and commented that the sights on the beach in Summer were not at all exciting.)  In April it is the haunt of seniors, many of them exercising their dogs, and thus a far more attractive place. Getting to the beach was a walk of about 1km along roads, from our van.  The second half of this went past a rather daggy looking paddock with many formed ridges in it, as though it was irrigated, although a water sources wasn't evident.  The paddock got interesting towards the end as some green parrots appeared.  Thanks to Frances eye for detail we have subsequently identified these as Elegant Parrots: my first lifer for 2014.    The locale is indicated by the red lines in this mudmap: Here are the bird...
