120 Report of the Meteorological Sub- Committee for 1893. 



wich of this century, the mean there being 51 -4°, an excess of 

 nearly 5*0° on the seventy years' average. The mean tempera- 

 ture is between 5-0° and 6-0^ above the average, and was at Bed- 

 dington 50-8^, at Waddon 51-5°, at Kenley 51-6°, and at WalUng- 

 ton 52-5°. SunHght at WalUngton reached the wonderful per- 

 centage of 65, an amount never yet equalled in any month since 

 the observations began, and this amount is no less than 28 per 

 cent, above the average. 



May. 



This month was very similar to the two preceding spring 

 months. The weather was less bright, and more rain fell than 

 in April ; but the air was drier and mean temperature slightly 

 more in excess ; it was warm throughout, the last two days being 

 the only cool ones. At Greenwich, with the exception of May, 

 1833 and 1848, it was the Avarmest May of the century, the 

 mean being 57'7°, nearly S-O"^ above the seventy years' average, 

 the May of 1848 being the warmest known, with an average of 

 59'7°. The mean temperature of the district was about 5-0° 

 above the average, and was at Beddington 55-8°, at Waddon 

 56-3°, at Kenley 56-5°, and at WalUngton, 57'5''. Sunlight at 

 Wallington was 50 per cent of the possible duration, being 7 per 

 cent, above the average. 



June. 



This was again a month of warm, fine, dry weather, not quite 

 so brilliant as April or May ; but notwithstanding ten or eleven 

 cool days, it was the warmest June at Greenwich since 1868, 

 when the mean was only 0-2° bigher than this year. After a 

 few showers on the 3rd and 6th a drought set in, which lasted 

 until the 23rd, and during this period there was a week of in- 

 tensely hot weather, the like of which has not happened in June 

 since 1858. The mean temperature of the month was about 

 3-0° above the average, and was at Beddington, 60-5, at Waddon 

 and Kenley, 60-9°, and at Wallington, 62-4°. Sunlight at Wal- 

 lington was about 45 per cent, of the possible duration, being 

 8 per cent, above the average. 



July. 



This was a month of broken weather, but except on the 14th, 

 15th and 16th, the air was never cold, and the nights were warm, 

 and consequently the mean of this month at Greenwich, like 

 every other one since January, exceeded the seventy years' 

 average, though only by 1-0°. It has been the warmest July 

 since 1887. The mean temperature is about 1-5° above the 

 average, and was at Beddington and Kenley 62 9°, at Wallington 

 63-1°, and at Waddon 63-2°, Sunlight at Wallington was only 

 37 per cent, of the possible duration, being 4 per cent, under the 

 mean.
