You can see Autumn from here!

The start of March was very warm, but it has cooled off a lot.

The trend for maximum gets disrupted by the warm Sunday 10^th, but the downward trend for minimum is very clear.

One way of assessing the relative warmth is by looking at the average temperature month to date for the current period and comparing that with the historic average.  (It is possible to approximate average temperature by the average of daily maximum and minimums.)  The difference between the current and historic averages is referred to as the anomaly.  This next chart shows the anomaly - currently 2.2^oC - as it has evolved though the month so far.

My conclusion is that if Autumn is not actually here yet we can certainly see it not too far away.

Interestingly the value of the anomaly is the same as has been calculated by another recorder for Bateman's Bay.
