SUMMARY FOR THE MONTH OF JANUARY, 1929.

January was a month of contrasts, a hot spell in the third week being followed by a cold snap of almost wintry severity. Rainfall was considerably below the average in the North Island and the western districts of the South Island, but in Canterbury and Otago an excess was generally recorded. Once more, there was an unusual frequency of thunderstorms, many of which were severe. In some cases these storms were accompanied by downpours resembling miniature cloud-bursts. Some remarkable hailstorms also occurred, considerable damage being done in a number of instances.

The storm systems were mainly centred far south, and of only moderate intensity. In consequence, the prevailing weather was of the westerly type, and the storms affected principally the South Island. High-pressure centres continued to follow unusually far northward tracks for the season of the year, but were seldom of any great intensity.

The deficiency of rainfall, following on the heavy rains of December, was not sufficient in the North Island to affect pastures adversely, and feed is everywhere abundant. The rankness of the growth has, in places, adversely affected the raising of fat lambs, but stock is, on the whole, in good condition. The hot, dry weather preceding the 20th was a boon to harvesters and haymakers, and satisfactory results are generally reported. Some crops have been flattened by wind, hail, or rain, but fungus diseases have made much less headway than was feared. Fruit-growers do not, on the whole, appear to be experiencing quite so good a season as other agriculturalists.

A very severe hailstorm, in which stones up to two inches in diameter were seen to fall, visited Otago on the 7th during the passage of a low-pressure wave. A number of crops were totally destroyed and other damage was done.

On the 8th January a deep depression was centred south of Tasmania, the Hobart barometer reading 28·96 inches. North-westerly gales were experienced in and south of Cook Strait on this day and the next.

On the 10th a terrific thunderstorm, accompanied by torrential rain, occurred near the Hermitage, some miles of road being washed out.

The week ending on the 19th was very hot, many places in the South Island recording over 90° F. In the North, though temperatures were not so high, the great humidity rendered conditions no less oppressive. Hawke’s Bay, however, appears to have escaped much of the severity of this heat wave.
