REMARKS 



July was marked by a very unusual hot spell from the 7th to the 

 11th, when the daily maximum temperature for a 5-day period did not 

 fall below 90 degrees, with a temperature of 96 on the 8th. These 

 high temperatures, together with high humidity and many hours of 

 bright sunshine, made the period a most uncomfortable one. Not 

 since 1919 have we experienced such a prolonged spell of hot weather, 

 when another 5 -day period of maximum temperatures ranging from 

 94.5 to 98 degrees was recorded. The all-time record for prolonged 

 excessive heat at this station was in 1911 when the daily temperature 

 for a 7-day period did not fall below 90 degrees, the highest tempera- 

 tures being 104, 102.5 and 101.5 degrees. Other excessive warm 

 spells were recorded in 1892, 1901 and 1912. 



The mean temperature for the month was 71.6 degrees, the nor- 

 mal for July being 70.6 degrees. The maximum temperature was 96 

 degrees on the 8th, and the minimum, 50 degrees on the 2nd. The 

 rainfall for July was 2.88 inches compared with a normal of 4.33 

 inches. The total precipitation since January 1 is now 29.71 inches, 

 with a normal of 25.22 inches for this period. There were 319 hours 

 of bright sunshine, the normal being 267 hours. Nineteen days classi- 

 fied as "clear", ten as "fair", and only two as "cloudy." The relative 

 humidity for the month of July was 68.3 per cent, the normal being 

 68 per cent. The total wind movement was 2725 milse compared with 

 a normal of 3435 miles. This is the lowest wind movement recorded 

 for July since 1921, when it was 2421 miles. 



The Pomology Department gives the following report on the 

 fruit crop: 



"The abundant and well distributed rainfall previous to August 

 I has resulted in the development of excellent foliage in the average 

 orchard and a rapid sizing of fruit. The moisture situation is very 

 different from that in 1936 when actual drought conditions existed 

 in many orchards. If rainfall during August is normal, we anticipate 

 favorable conditions from the standpoint of maturing the apple crop. 

 On the other hand, if drought conditions prevail, it is reasonable 

 to expect a premature drop of fruit on certain varieties such as 

 Mcintosh and perhaps the development of bitter pit or stippen in 

 Baldwins. Rainfall and humidity during July have favored a secondary 

 infection of apple scab which has necessitated emergency measures 

 in the average orchard."
