Kerala is bestowed with a pleasing and equable climate throughout the year, could be a tropical land with the coast running down its entire length and the Western Ghats forming a protecting barrier against the dry winds from up north. In Kerala, the 3 major seasons are summer (February-May), monsoons (June-August and October-November) and winter (December-January) with a pleasing interval of gentle weather between August and October. There is no fall season, with any noticeable falling of leaves. Instead, towards the peak of summer (March-April-May), there is a partial falling of leaves. it would still be hot summer, as your wet body would tell you.
It gets progressively hot throughout the summer season from February to May. a number of showers in March or April would possibly cool things slightly (not much). Temperatures generally reach 35 degrees centigrade and also the blazing sun isn't any pleasant experience. Tree leaves become dry and start to fall, though few trees become completely clean of leaves.
In Kerala the ‘season’ never comes to an end. The tourists are attracted towards India usually in the months September to April, but in Kerala they are welcomed during the monsoon months as well. It is mainly because we have the popular Ayurveda health holidays and also provides beautiful sight of the nature.
Monsoon could be a excellent season that is welcome by all with nice happiness. The word monsoon itself brings a smile on everyone’s face. The factors that create monsoon the favourite season is that the splashing waters, intoxicating smell of the wet earth etc. Monsoon comes as a boon after long months of hot climate. it is a change to the climate and temperature once the monsoon arrives after the summer months and also a relief from the dust and heat. In Kerala the monsoon rains do not rain continuously for weeks. they may rain for few hours and every now and then it may extend for two or three days. it is terribly beautiful to see the sun shining brightly soon after a rain.
South-west monsoon (Edavappaathi)
The rainy season in Kerala is the Southwest monsoon. In malayalam this season is called as Edavappaathi which means in the middle of the malayalam month Edavam. It is called so because the rain starts by the middle of this month that is the end of May or early June. The following two months have torrential rain. As Kerala lies on the windward side of the Western Ghats and is the first state to get hit by the monsoon winds, this state receives heavy rainfall. Winds from South-West, bearing water vapor, begin to blow from the oceans. Heavy rain clouds cover the sun and rains begin to pour. It is dark and cool (or wet, if you are outside a comfortable shelter). It is the monsoon that provides almost 85% of the rains. The slopes of the Western Ghats receive the highest amount of rain. The rivers get flooded by the monsoons. This season continues till the end of September.
The south-west monsoon lasts till around August and there is a pleasant interval of two months or so before north-east monsoon takes over. The weather is mild and it is celebration time in Kerala. Flowers bloom, rice is harvested, there is feasting and entertainment programs (like boat races) and people go shopping in a big way.
North-east monsoon (Thulavarsham)
The North east monsoon is also known as the Retreating Monsoon or the Reverse monsoons. This hits Kerala when the southwest monsoon winds take their return. These rains are called as Thulavarsham in malayalam because it rains during the malayalam month thulam. It comes in the month October and November and at times continues up to December. The main feature of this season is heavy rains during afternoon together with lightening and thunder. The days are usually warm and humid without much variation in temperature.
In Kerala the winter season starts when the northeast monsoons ends. That is from the month November till the middle of February. During this time, the temperature is less but it does not have much difference with the other seasons. The temperature remains cool constantly throughout the year in the highlands but the winter temperatures falls below 15°C. It is during this winter season that we receive some of the lowest amount of rainfall.
A fog might cover trees and buildings in the mornings and it would generally be a pleasant time. In Kerala, it is also the time for such major pilgimages as sabarimala and thiruvairanikulam. It is also the season of Christmas and the coming of a new year. The Muslim festival of Eid Ul Fitr also occurs around this period.
Towards January end, summer would be nearing and the cycle starts again.
The temperature starts to increase with the end of February which indicates the beginning of summer in Kerala. The characteristics of summer in Kerala are relatively higher temperature, less rainfall and humid weather. The other Indian states have a temperature of about 40°C, whereas in Kerala it is comparatively cool and pleasant. It is mainly because of the presence of the Western ghats that prevents the northern wind from entering our state. We also have the Arabian sea bordering us that gives a cool breeze which helps to make the temperature moderate. Another important feature of this season is the arrival of rain which is accompanied by thunder and lightening. The summer season extends from March till May or the beginning of June. It ends with the beginning of monsoon.
The pleasant and good climate of Kerala is attracted by many tourists every year. The peak tourist seasons are winter and summer. The most exciting things to do during these seasons are to cruise in the houseboats on the backwaters of Kerala, to see the beauty of sunset from Kovalam beach during summer, boating in the Thekkady lake, trekking in the highlands of Kerala during winter etc. All these would definitely be a memorable experience. And for those who like to enjoy a cloudy day, scent of wet sand etc, monsoon is suggested.
