Abstract

THE weather conditions for the three summer months, June to August, have proved very disappointing, and the principal characteristic has been the entire absence of warm days. At Greenwich which have only been forty days during the whole period with a temperature of 70° and above. This is precisely the same number as in the phenomenally wet summer of 1903, but it is very greatly below the average. In 1860 there were only twenty-three days with a temperature, of 70° or above, and in 1879 twenty-six such warm days, so that the past summer is not unique. There has not been, however a single day this summer with a temperature of 80°, whilst in 1903 the thermometer touched that reading on six days. The aggregate rainfall at Greenwich for the three months was 5.29 inches, which is 1.37 inches less than the average of the past sixty years. In 1903 the aggregate for the corresponding three months was 16.17 inches, which is the wettest summer on record. At the London observing station of the Meteorological Office the aggregate rainfall for the three months was 4.76 inches, which is 2.13 inches below the normal and the only month with an excess so far this year is April. June was generally wet over nearly the whole country, July was mostly dry, whilst in August the rainfall varied considerably in different parts of the kingdom. At Jersey the total measurement in August was 0.60 inch, whilst the average is 2.48 inches; at Valencia the measurement was 5.67 inches. The sunshine has not varied much from the average. In London there was a slight deficiency in each month, but in the aggregate for the three months it only amounts to thirty-eight hours. September has commenced with exceptionally cold weather, and the thermometer for the first four days has averaged about 30° lower than at the corresponding time last year.
