The climate of Kerala is considerably different from European and North Asian. It is defined as moist tropical, or subequatorial. In the hottest period - March-April - during the day the temperature rises up to +36 °C. In winter the average temperature of air is +22..28°C in the daytime. In summer it is hot and moist here, up to +32°C. There are two rainy seasons (monsoon): June-July and October, but it may rain any time during the year..
It is evident, that in Kerala seasons are very different from European and North Asian seasons. However, panchakarma (cleansing the organism) will be most effective only in case if it is conducted in the correspondence with the seasons of the climate, in which the patient lives. For example, winter in Europe, as well as winter in the Himalayas, is the least favorable time for cleansing the organism, since the human body stocks substance for its strengthening in the cold season and all internal processes work on the storing substances, but not on the output and release, what the process of cleansing requires. However, in Kerala the best weather for tourist season is in winter. And this is undoubted so, if you arrive in Kerala just to relax, to enjoy the weather and ocean. But if your main task is panchakarma, then all processes, which take place in your organism in accordance with your native, but not Keralian season, will prevent cleansing process, since within a short period your body will not attune to the rhythms of another climate.
