SUMMARY FOR THE MONTH OF MAY, 1921.
Dull and misty weather was much in evidence during May, but except in the West Coast districts of the South Island the total rainfall was everywhere considerably less than the average.
Westerly disturbances ruling between the 7th and 13th and from the 24th to the end of the month accounted for unsettled and squally conditions during these two periods, with rain in many parts, particularly in districts with a westerly aspect.
Although anticyclonic pressure prevailed from the 12th to the 24th, the weather proved cold and dull, owing to the proximity of depressions eastward and southward of the Dominion.
