The temperature, while not exceptionally high, is very constant. 
The hot months extend from September to January, the highest 
temperature occurring in October. The months of April and May 
are slightly cooler. During the rainy season a fall of two to four 
degrees centigrade occurs about daybreak, so that the early hours of 
the day are quite refreshing. The thermometer averages about 
24 ‘ 5 ° C. at 6 a.m., at which time there is generally a light N.E. breeze ; 
at noon, a slight breeze may spring up for a short time.
