Remarks. 



The mean temperature for the month of August, 1891, at 

 those stations in Massachusetts having records for more than 

 ten years, was slightly above the normal, being somewhat in 

 contrast with the month of July in this respect. The amount 

 of excess varied from 0.9° at Boston to 1.6° at Springfield. 

 The days of highest temperature were the 10th, 11th and 

 12th, although the days from the 21st to 28th, under the 

 hot moisture-laden southerly winds that prevailed were 

 oppressively warm. The maximum was several degrees 

 lower than was experienced in June (an unusual fact) and 

 occurred on the 11th, except along the coast where a well 

 defined sea-breeze was felt. This breeze was first noted at 

 Swampscott at about nine o'clock a.m. and from thence 

 extended well inland. At Cambridge the heat on the 11th 

 was considerably tempered by the sea-breeze but at Chestnut 

 Hill it was scarcely felt, and at Lake Cochituate and Concord, 

 not at all, or if felt it was too late to influence the maximum 

 temperature. The minimum temperature occurred generally 

 on the morning of the 1st, but it was very cool on the 3d, 

 20th and the last three days of the month. No frost has 

 been reported. 



The number of cloudy and rainy days was in excess, 

 except at Nantucket and a few other local sections, but 

 the precipitation was nearly one inch below the average. 

 The thunder-storms were neither frequent nor unusually 

 heavy. High wind accompanied a storm on the 12th, which 

 did some damage to fruit and crops, and slight damage was 

 done by heavy rains on the 28th. At Amherst 0.35 inches 

 of rain fell in ten minutes, and at Provincetown over one 

 inch fell from 3.55 to 4.40 p.m. Heavy rains fell, also, at 

 Nantucket on the 30th.
