Tables are given below showing the monthly record of rainfall and 

 temperature. Rainfall is not always a vital point for consideration in 

 many temperate regions, but in the tropics, where the precipitation 

 takes such a prominent place at certain periods of the year and at times 

 causes such destruction, before constructing important engineering works 

 it is absolutely necessary to know the amount of rainfall and whether it 

 is apt to be concentrated.
