SUMMARY FOR THE MONTH OF APRIL, 1917.
The rainfall during April was abundant in the Auckland Province and in all districts with a westerly aspect. A deficiency occurred in Hawke's Bay and also on the east coast and southernmost districts of the South Island.
The principal disturbances were of the westerly type, with lowest atmospheric pressure passing southwards of New Zealand. Of these, one ruling between the 1st and 2nd, and another between the 13th and 17th, were somewhat intense, and resulted in stormy conditions in many parts of the Dominion.
Minor depressions of this character also passed on the 5th, 8th, and 28th.
From the 22nd to the 26th, although an anticyclone was centered in the south, relatively low pressure ruled to the northwards, causing high easterly winds and considerable rainfall in the northernmost districts.
The weather generally was changeable, but temperatures were mild, except towards the close of the month, when very cold conditions brought a reminder of approaching winter.
