SUMMARY FOR DECEMBER, 1909.
THE rainfall was above the average in Hawke’s Bay, Marlborough, and North Canterbury Districts, but considerably below the average elsewhere. There were fewer days with rain than usual. The most remarkable and memorable meteorological occurrence was the heavy southerly gale which commenced in the South on Christmas Eve, and extended over the whole of the Dominion on the 25th and 26th, causing a general and heavy rainfall. This storm was caused by a combination of forces—the rear winds of a cyclone off the east coast of the North Island and a small westerly area of low-pressure in the South operating with the winds of an advancing high-pressure system. Violent westerly winds followed in the southern districts until the end of the month, with very unsettled weather.
