MEANS AND EXTREMES OF TEMPERATURE AT NASSAU.

The seasons are not sharply marked by temperature changes as in regions 

 farther north. The mean of the three winter months is 71. From June 

 to September the average monthly temperature is extremely constant, varying 

 only between the limits of 81.5 for June and 83.4 for August, with an 

 average for the four warmest months of 82.4. Hence the difference between 

 the winter temperatures and those of summer is only 11.4. The mean of 

 the early morning temperatures in winter is 65.0, while the mean for the 

 warmest part of the day is 77.7. In the summer months the morning mini- 

 mum and afternoon maximum heat averages 76.3 and 88.5 respectively. 



The figures cited in the preceding paragraph are average seasonal values 

 and do not show the limits of variability. The absolute extremes of tem- 

 perature noted, while showing a much greater range, are still small enough 

 to demonstrate the marine character of the climate. The lowest temperature 

 recorded during the five-year period under consideration was 53, which 

 occurred on the 14th day of February, 1899. The highest during the same 

 period was 98, recorded on the 25th day of June, 1898. 



ABSOLUTE EXTREMES OF TEMPERATURE AT NASSAU. 



A careful examination of the published records from 1853 to 1886, and 

 of the manuscript records from 1898 to 1902, covering in all a period of 39 

 years, shows the following figures of extreme heat and cold experienced at 

 Nassau during each month of the year. The year and day of occurrence are 

 added in each case.
