Must be one of the driest Augusts on record here in the auckland area (although eastern parts of the auckland area received more rain in the last rain epoiside we had (that northerly front)
maybe aslo one of the lowest rain days on record too?
Since 1914 lowest rain total for auckland?
maybe also one of the sunniest augusts?
and least windiest?
temperatures only normal here, maybe even slightly below normal (colder nights?)

It certainly is good to have decent rain of late as although the year to date amount looks ok around 150mm of that fell on the one day in February.
