DIAGRAM EXHIBITING THE COMPARATIVE FALL OF RAIN ON THE SEABORDE OF THE DEEKAN, AND AT COLOMBO, IN THE WESTERN PROVINCE OF CEYLON.
One maximum at the spring change of the monsoon anticipating a little that on the West coast of India; another at the autumnal change corresponding more exactly with that of the East coast. The entire fall through the year more equably distributed at Columbo.
On the east coast, on the other hand, the fall, during the north-east monsoon, is very similar in degree to that on the coast of Coromandel, as the mountains are lower and more remote from the sea, the clouds are carried farther inland and it rains simultaneously on both sides of the island, though much less on the west than during the other monsoon.
The climate of Galle, as already stated, resembles in its general characteristics that of Colombo, but, being further to the south, and more equally exposed to the influence of both the monsoons, the temperature is not quite so high; and, during the cold season, it falls some degrees lower, especially in the evening and early morning.[1]

Kandy, from its position, shares in the climate of the western coast; but, from the frequency of the mountain showers, and its situation, at an elevation of upwards of sixteen hundred feet above the level of the sea, it enjoys a much cooler temperature. It differs from the low country in one particular, which is very striking—the early period of the day at which the maximum heat is attained. This at Colombo is generally between two and three o'clock in the afternoon, whereas at Kandy the thermometer shows the highest temperature of the day between ten and eleven o'clock in the morning.
In the low country, ingenuity has devised so many expedients for defence from the excessive heat of the forenoon, that the languor it induces is chiefly experienced after sunset, and the coolness of the night is insufficient to compensate for the exhaustion of the day; but, in Kandy, the nights are so cool that it is seldom that warm covering can be altogether dispensed with. In the colder months, the daily range of the thermometer is considerable—approaching 30°; in the others, it differs little from 15°. The average mean, however, of each month throughout the year is nearly identical, deviating only a degree from 76°, the mean annual temperature.[1]
