SUMMARY FOR THE MONTH OF JULY, 1923.

July was characterized by cold, dull, and damp weather, although the total rainfall was below the average over the
greater part of the Dominion. An excess was experienced only at a few places in the northern and east coast districts
of the North Island, and in North Canterbury in the South.

A westerly depression between the 1st and 6th accounted for heavy and widespread falls of snow in the highlands of
the South Island.

From the 7th to the 9th anticyclonic conditions and fair weather prevailed, and this was the only period during which
such conditions were general. The remainder of the month was very dull, misty, and showery, but heavy rain fell on the
14th and 15th in the northern and east coast districts of the North Island, owing to the passage of a cyclone centred northward
of New Zealand.

The barometer rose very high towards the close of the month, but the weather, though fine over most of the country
continued cold and showery with strong south-easterly winds in the east coast districts. This was accounted for by a
disturbance which persisted in the neighbourhood of the Chatham Islands on the edge of the anticyclone.
