AVERAGE TEMPERATURES FOR AUGUST 



SEPTEMBER 



Sky: The month of September generally contains a good pro- 

 portion of fair bright days. Our table for 1900 shows a consider- 

 able excess of cloudy days, but the conditions are reversed in 1903, 

 when, however, we have only about a third of the month repre- 

 sented. In 1906, the records cover only the first 19 days and are 

 expressed in too general terms to easily adapt themselves to tabu- 

 lar form, but which, of the 19 days, record 16 days as "fine" or 

 "fair weather" and 3 as cloudy or showery. The only fairly com- 

 plete record for September is that of 1900. In 1902 we have 

 scattered records covering 6 days, too fragmentary to be tabulated. 

 In 1903 we have continuous records only from the 21st to the 

 30th, but as these are pretty full records they are entered. 



Winds: Calm days are frequent. In September, 1900, south 

 winds were the most prevalent. In September, 1906, northeast 

 winds were frequent ; these are usually cold disagreeable winds. 



Storms: Rainstorms are rather frequent most years and are 

 accompanied by cool weather. Fogs are occasional, and this is 

 the month of the first frosts. 



The following is the table for the two years : 



Temperatures: The total number of temperature records for 

 September is 452, as follows : 84 in 1899, 88 in 1900, 11 in 1902, 25 

 in 1903, 52 in 1906, 61 in 1907, 47 in 1908, and 84 in 1913. 



The lowest temperature recorded was 37 on September 29 and 

 30, in 1899; the highest was 95 on September 1, 1913.
