the somali current is characterized by seasonal changes influenced by the southwest monsoon and the northeast monsoon. during the months of june to september, the warm southwest monsoon moves the coastal waters northeastward, creating coastal upwelling. the upwelled water is carried offshore by ekman transport and merges with water that was brought to the surface by open-ocean upwelling. the findlater jet, a narrow low-level, atmospheric jet, also develops during the southwest monsoon, and blows diagonally across the indian ocean, parallel to the coasts of somalia and oman. as a result, an ekman transport is created to the right of the wind. at the center of the jet, the transport is maximum and decreases to the right and left with increasing distance. to the left of the jet center, there is less water movement toward the center than is leaving, creating a divergence in the upper layer and resulting in an upwelling event (ekman suction). in contrast, to the right of the center of the jet, more water is coming from the center than is leaving, creating a downwelling event (ekman pumping). this open-ocean upwelling in combination with the coastal upwelling cause a massive upwelling. the northeast monsoon, which occurs from december to february, causes a reversal of the somalia current, moving the coastal waters southwest. cooler air causes the surface water to cool and creates deep mixing, bringing abundant nutrients to the surface.

with around 120–140 rainy days per year, kerala has a wet and maritime tropical climate influenced by the seasonal heavy rains of the southwest summer monsoon and northeast winter monsoon. around 65% of the rainfall occurs from june to august corresponding to the southwest monsoon, and the rest from september to december corresponding to northeast monsoon. the moisture-laden winds of the southwest monsoon, on reaching the southernmost point of the indian peninsula, because of its topography, divides into two branches; the "arabian sea branch" and the "bay of bengal branch". the "arabian sea branch" of the southwest monsoon first hits the western ghats, making kerala the first state in india to receive rain from the southwest monsoon. the distribution of pressure patterns is reversed in the northeast monsoon, during this season the cold winds from north india pick up moisture from the bay of bengal and precipitate it on the east coast of peninsular india. in kerala, the influence of the northeast monsoon is seen in southern districts only. kerala's rainfall averages 2,923 mm (115 in) annually. some of kerala's drier lowland regions average only 1,250 mm (49 in); the mountains of the eastern idukki district receive more than 5,000 mm (197 in) of orographic precipitation: the highest in the state. in eastern kerala, a drier tropical wet and dry climate prevails. during the summer, the state is prone to gale-force winds, storm surges, cyclone-related torrential downpours, occasional droughts, and rises in sea level. the mean daily temperature ranges from 19.8 °c to 36.7 °c. mean annual temperatures range from 25.0–27.5 °c in the coastal lowlands to 20.0–22.5 °c in the eastern highlands.
