SUMMARY FOR THE MONTH OF JULY, 1917.
In the East Coast districts of the North Island, Otago, and in parts of Westland the total rainfall did not reach the average, but elsewhere a considerable excess was recorded.
Numerous atmospheric depressions were in evidence, particularly during the latter half of the month, and the barometer remained continuously below normal until the last day.
On the 20th, when a cyclone held sway, some exceedingly low barometer readings were reported, especially about Cook Strait.
Except in the districts above mentioned, very unsettled and wet weather prevailed, but nearly all parts of the Dominion experienced mild temperatures.
Owing to the neutralizing effect of the various “lows” on each other, the average velocity of the wind was less than what might have been expected in a month having so many disturbances.
