SUMMARY FOR THE MONTH OF AUGUST, 1917.
The rainfall during August was in the east coast districts of the South Island considerably less than the average, and also slightly less along the north side of Cook Strait. The northern and east coast portions of the North Island generally show an excess, but in the remaining districts the falls were very uneven.
Following is a brief description of the principal atmospheric disturbances: On the 1st and 2nd a cyclone of moderate intensity moved down the west coast, the centre passing in the south on the night of the 3rd. Dull, misty, and wet weather prevailed generally, and heavy rain fell in the northern districts on the 1st.
Cold, squally, and showery conditions were experienced on the 5th, when a small depression ruled in the far north.
Between the 7th and 10th, while high atmospheric pressure prevailed over the South Island, an intense cyclone passed northwards of the Dominion, causing high south-easterly winds in and northward of Cook Strait, with passing showers, but heavy rain was experienced in the northern and east coast districts.
A westerly storm passed over the Dominion between the 12th and 14th, and on the 12th and 13th northerly gales ruled with boisterous and wet weather. On the 14th the winds changed to southerly, bringing a cold snap. This was accentuated on the latter date by the presence of a secondary “low” which developed off the west coast of the North Island, but disappeared the same night.
A small cyclone passed off East Cape on the 19th, and accounted for rain, particularly in the north. This was followed by a westerly area of low pressure which persisted until the 27th. During this period the weather was very changeable, occasionally squally and wet in parts.
Short periods of anticyclonic conditions and fine weather were experienced generally on the 10th and 11th, between the 16th and 18th, and from the 28th to the close of the month.
