REMARKS.
CHRISTCHURCH.
During the month of February, remarkably fine weather prevailed in this district; bright sunny days and clear starlight nights followed each other almost without interruption. The rainfall was very slight, only 0.455 inches, which fell on five occasions, and always in the night-time; the largest amount collected in 24 hours was 0.122 inches, on the night of the 21st. The heat was sometimes very oppressive, particularly on the 11th, 17th, 20th, 21st, and 25th, on which days the temperature in shade rose above 80°, the highest being 84.8° on the 21st. Solar radiation shows a higher monthly mean than has been yet registered at the station during the last four summers, namely, 115.7°; on only one day did the maximum heat in the sun's rays fall below 100°.
