SUMMARY FOR THE MONTH OF APRIL, 1921.
Rainfall was again below the average, with the greatest deficiency in districts with an easterly aspect. Anticyclonic systems were dominant during the first week, between the 15th and 17th, and from the 22nd to the close of the month. The weather proved fair generally about these periods, with fine, clear days and frosty nights.
From the 7th to the 14th a very intense westerly disturbance brought unsettled, and at times stormy, conditions. High north-west winds backed to southerlies on the latter date, but the weather then rapidly improved.
Another, but less intense, westerly “low” was in evidence between the 18th and 21st, when squally conditions prevailed, and occasional rain fell. In the early-morning hours of the 19th a severe electrical disturbance was experienced in the vicinity of Cook Strait, accompanied by heavy rain showers.
The shade temperature for the month was generally about 2·5 degrees F. below the April mean.
D. C. BATES, Director.
