Compared to other Indian states, Kerala lies closer to the equator. Yet Kerala is bestowed with a pleasant and equable climate through out the year. This is because of the land’s nearness to the sea and the presence of the fort like Western Ghats on the east. Kerala would have been a dry land because of the dry winds blowing from the north, but for the Western Ghats which prevent this wind from entering the land. Kerala receives copious rain (average 3000 mm a year )each year. The temperature in Kerala normally ranges from 28° to 32° C (82° to 90° F) on the plains but drops to about 20° C (68° F) in the highlands. The Highlands of Kerala, which is an area of major tourist attraction, enjoys a cool and invigorating climate the year-round .
