Rainfall above normal in May relieved seasonal shortages somewhat, and long-duration shortages slightly. It failed to prevent a new record rainfall shortage at 15 months (388 mm).
As the median rainfall total for 15 months is 796 mm, that is a shortfall of 408 mm.
To make up for that, we need not just normal rainfall, but eight months of extra rainfall above the normal amount.

Sydney water managers are citing low reservoir levels as evidence of water shortage. That does not direcly relate to rainfall shortages that I am documenting.

The contour graph above is one of a series that I have now put on a single blog post so they can all be compared:
https://climatebysurly.com/2019/06/18/rainfall-shortage-series-of-contour-plots/
Five of the contour graphs show the 2018-19 drought. One shows to 2002 drought and one the 1994 drought.
These are the only notable droughts at Manilla in the last half-century.

Certainly still a shortage, but at least we may fill up our water tank with this current event.
Hunter Water haven't imposed water restrictions yet, but are having a field day with no rain water available for a while now.
