RAINFALL AT COTTAYAM AND METEOROLOGICAL

NOTES.

THE two following Tables represent the rainfall for 1861 and 1865. The average lies between the two; the fall in 1861 having been below, in 1865 above, the average.

December, January, and February are usually without rain. Evening showers commence in March or April from thunderclouds that gather about the mountains in the East. The S.W. monsoon sets in in the end of May or beginning of June; it closes by the end of August. September gives us occasional showers. In October and November the N.E. monsoon often sends us heavy storms.

Cottayam is, as nearly as possible, in lat. 9 N., long. 76 E. It is 17 miles from the coast, and about 150 feet above the level of the sea.

The average of rainfall at Cottayam is very much greater than at Trevandrum.
