These islands have a tropical humid, warm and pleasant climate, becoming more equatorial in the southern islands of the territory. The climate is equable with no distinct, well marked seasons. Southwest monsoon period is the chief rainy season which lasts from late May to early October. The rainfall in the southern islands is more evenly distributed than over the north island. The number of rainy days during the southwest monsoon season is more in the north than in the south..
Temperatures are generally uniform over the territory, increasing but slightly from South to North. April and May are the hottest months in the year. Summer temperatures range from 35 Degrees CeDuring fair weather the days are warm and stuffy due to humidity. Nights are generally pleasant because of the cool sea breeze.
Winds are light to moderate during October to March or April. Towards late Summer, winds begin to strengthen and continue to be strong in the southwest monsoon season. Northerly or North-Easterly winds prevail during the months of December to February.
The Cyclonic storms have deposited coral debris forming coral beach and the lagoons. The islands are thus open to storms and cyclones. One of the earliest natural calamities was the great storm on April 15, 1847. All the houses in Andrott, Kiltan Kalpeni were damaged and many were entirely washed away.
In 1891, a violent storm burst upon Kavaratti island causing considerable damage to coconut trees. The storm did a great deal of damage in Agatii and its attached islets and the Amindivi group of islands. Kalpeni island was hit by a severe cyclone on December 1, 1922. The sea poured across the island into the lagoon. In 1941 another major storm hit the islands and Kavaratti was the most affected by the storm. In 1963, a cyclone of mild intensity struck Andrott island uprooting many coconut trees. The major storm was in December 1965 which cause considerable damage in Andrott and Kalpeni islands uprooting a large number of coconut trees.
Some of the cyclonic depression and storms which form in the South Arabian Sea during April-May affect the weather of Lakshadweep. During the months of October to December a few of such systems originating in the Bay of Bengal and moving westwards emerge into the South Arabian Sea and some times affect these islands resulting in strong wind and heavy rains.
