It is to be noted that the climate of the islands of the Pacific becomes more and more healthy the farther they are from the monsoon region.
The wet season, lasting during the prevalence of the south-west monsoon, from April to December, is clearly defined on the Pacific slope.
Tibet is affected by the south-west monsoon, just as the Pamirs are affected, but in varying degrees according to geographical position.
The northwest monsoon, beginning in October and lasting till March, brings the principal rainy season in the archipelago.
In the two years 1899 and 1900 the monsoon was very weak, the result being a severe famine which caused great mortality among the Bhil population.
