Climate of Kerala.

Although Kerala lies closer to the equator than most Indian states, it is blessed with pleasant and equable climate throughout the year. This is because of the land’s nearness to the sea and the presence of the natural fort like Western Ghats on the east that protect the state from dry and hot winds blowing from the north. Kerala receives copious rain (average 3000 mm) each year. The temperature normally ranges from 28’C to 32’ C (82’F to 90’ F) on the plains but drops to about 20’C (68’ F) in the highlands. The Highlands of Kerala, enjoys a cool and invigorating climate the year-round. Owing to its diversity in geographical features, the climatic condition in Kerala is diverse. It can be divided into 4 seasons - Winter, Summer, South-West Monsoon and North-East Monsoon.

Winter Season in Kerala : Starts with the end of the northeast monsoons i.e. from the later part of November lasting till the middle of February. During this season temperature is comparatively low but as does not vary much from other seasons. In the Highlands where the climate is cool throughout the year, winter temperatures often fall below 10’C. This season witnesses the lowest amount of rainfall.
Summer Season of Kerala : At the end of Feb. temperature starts rising and this marks the beginning of summer in Kerala. Relatively higher temperature, low rainfall and slightly humid weather are the characteristics of this season. When compared to other Indian states where temperature soars to over 40’C, summers in Kerala are cool and pleasant. The Western Ghats help prevent the dry northern winds from entering the state and the cool breeze from Arabian sea blows in. Irregular rains is  another feature of this season. Starting in March, the summer season continues till the end of May or the beginning of June, when the Monsoon sets in.
South West Monsoons Season in Kerala: Southwest monsoon is the main rainy season of Kerala. This season begins around the end of May or early June with the outset of the southwest monsoon winds. The next few months are periods of torrential rain. Lying on the windward side of the Western Ghats and being the first state to be hit by the monsoon winds, Kerala receives copious rainfall. Almost 85% of the rain is contributed by the monsoons. The slopes of the Western Ghats are among the places in India which receives the highest amount of rain. Most of the rivers of Kerala are fed by the monsoons. The southwest monsoons last till the end of September
North East Monsoons also known as the Retreating Monsoons or the Reverse monsoons is during the return of the southwest monsoon winds. These rains are in the months of October and November and sometimes it can last till December. Days are warm and humid but there is not much variation in temperature.
